The PXI-5650 and PXIe-5650 provide similar RF functions but use different chassis interfaces and are not interchangeable in every PXI slot.<\/p>\n<h3>500 kHz to 1.3 GHz Frequency Coverage<\/h3>\n<p>The PXI-5650 provides calibrated signal generation from 500 kHz through 1.3 GHz. This range covers baseband and intermediate-frequency applications as well as broadcast, industrial, navigation, automotive and sub-GHz wireless systems.<\/p>\n<p>The generator can tune down to 100 kHz, but amplitude accuracy is not calibrated below 500 kHz. Applications requiring traceable output-level accuracy should remain within the calibrated operating range.<\/p>\n<h3>12 dBm Maximum RF Output<\/h3>\n<p>The PXI-5650 supplies maximum output power as high as 12 dBm, depending on frequency and operating conditions. Programmable level control allows the same module to generate lower-power signals for receiver sensitivity and threshold testing.<\/p>\n<p>The power delivered to the device under test differs from the value at the generator connector when the signal passes through cables, attenuators, adapters or RF switches. Apply appropriate path-loss correction or measure the signal at the final reference plane.<\/p>\n<h3>Direct Digital Synthesis Architecture<\/h3>\n<p>The onboard DDS circuit provides fine control of the generated frequency and supports phase-continuous changes between frequency settings. Frequency resolution is less than 3 Hz across the PXI-5650 calibrated operating range.<\/p>\n<p>DDS control is useful when the test requires precise carrier placement, small frequency steps, programmable sweeps or nonstandard clock frequencies.<\/p>\n<h3>Continuous-Wave Generation<\/h3>\n<p>The PXI-5650 operates as a programmable continuous-wave RF source. Engineers can set the required carrier frequency and output level through software and then use the signal to stimulate an RF component or receiver.<\/p>\n<p>Typical CW measurements include amplifier gain, filter response, receiver sensitivity, mixer conversion loss, cable insertion loss and RF switch-path verification.<\/p>\n<h3>Phase-Continuous Frequency Sweeping<\/h3>\n<p>The module can perform DDS-based phase-continuous frequency sweeps for fixture and device characterization. The carrier moves through a list of frequency points without restarting an unrelated waveform at every step.<\/p>\n<p>When combined with an RF analyzer or power detector, a sweep can measure gain flatness, filter response, passband ripple and signal-path insertion loss.<\/p>\n<h3>Programmable Frequency Hopping<\/h3>\n<p>Configuration lists allow the PXI-5650 to move through predefined frequency and power settings. Hardware or software triggering can advance the generator through the list during an automated test.<\/p>\n<p>The typical frequency tuning time is 1.5 ms. Complete test speed also depends on the receiving instrument, switch settling time, device response and software execution.<\/p>\n<h3>Frequency Modulation<\/h3>\n<p>The PXI-5650 supports onboard frequency modulation using programmable modulation settings. Internal FM waveform options include sine, triangle and square patterns.<\/p>\n<p>FM generation can be used to test analog receivers, discriminators, demodulators and communications circuits. Confirm that the selected carrier, modulation rate and frequency deviation remain within the device\u2019s supported limits.<\/p>\n<h3>Two-Frequency FSK Generation<\/h3>\n<p>Two-frequency FSK switches the carrier between two defined frequency states. This basic digital modulation is commonly used in industrial radios, telemetry systems, remote controls and low-data-rate wireless devices.<\/p>\n<p>The PXI-5650 can provide controlled FSK stimulus for receiver functional testing and bit-error-rate measurements. Additional digital hardware may be required to provide or evaluate the test-data pattern.<\/p>\n<h3>On-Off Keying Generation<\/h3>\n<p>On-off keying represents information by enabling and suppressing the RF carrier. It is widely used in wireless remotes, keyless-entry systems, basic sensor transmitters and identification devices.<\/p>\n<p>Automated software can vary the carrier frequency, output power and OOK timing to determine whether the receiver operates correctly across its specified range.<\/p>\n<h3>Phase Modulation Support<\/h3>\n<p>The NI-RFSG programming interface provides programmable phase-modulation controls for supported 5650-series RF generators. This allows basic PM signals to be produced without adding a separate modulation source.<\/p>\n<p>The PXI-5650 is not a wideband vector signal generator. Complex arbitrary I\/Q formats such as QAM, OFDM, LTE or WLAN require a vector signal generator or vector signal transceiver.<\/p>\n<h3>Phase-Noise Performance<\/h3>\n<p>The PXI-5650 typical single-sideband phase noise at a 10 kHz offset is less than -125 dBc\/Hz at 100 MHz, less than -111 dBc\/Hz at 500 MHz and approximately -105 dBc\/Hz at a 1 GHz carrier.<\/p>\n<p>Low phase noise helps preserve CW signal purity and improves receiver selectivity, oscillator and adjacent-channel measurements. Actual performance depends on carrier frequency, offset, reference-clock configuration and environmental conditions.<\/p>\n<h3>Low-Jitter Clock Generation<\/h3>\n<p>The generator can be used as a programmable clock source for circuits requiring nonstandard sample frequencies. NI identifies baseband and intermediate-frequency clocking as an application for this signal-generator family.<\/p>\n<p>At 622 MHz, the typical integrated jitter is below 200 fs under the specified measurement conditions. Confirm that the receiving circuit accepts the sine-wave level, impedance and spectral characteristics of the RF output.<\/p>\n<h3>External 10 MHz Reference<\/h3>\n<p>The REF IN\/OUT connector can accept a 10 MHz external reference or export the module\u2019s onboard 10 MHz reference. The specified external input range is 0.2 Vpk-pk to 1.5 Vpk-pk into 50 \u03a9, with a lock time of less than one second.<\/p>\n<p>Using a common frequency reference helps coordinate the PXI-5650 with analyzers, counters and additional RF generators. Frequency locking does not automatically establish a fixed RF phase relationship between separate instruments.<\/p>\n<h3>PXI Timing and Triggering<\/h3>\n<p>The PXI-5650 can use PXI backplane trigger resources to coordinate configuration-list steps and generation events with other modular instruments.<\/p>\n<p>Hardware triggering improves repeatability when the generator must change frequency or power at a defined point in the measurement sequence. The exact trigger source and behavior should be configured through NI-RFSG.<\/p>\n<h3>Front-Panel Connections<\/h3>\n<p>The RF OUT connector supplies the programmed RF signal at the selected frequency and power. The REF IN\/OUT connector routes a frequency-reference signal into or out of the module.<\/p>\n<p>Use correctly rated 50 \u03a9 coaxial cables and SMA accessories. Protect the RF output from excessive reverse power and DC voltage, particularly when connecting the generator to active transmitters or powered circuits.<\/p>\n<h3>Typical PXI-5650 Applications<\/h3>\n<ul>\n<li>RF receiver sensitivity testing<\/li>\n<li>FM receiver validation<\/li>\n<li>FSK and OOK communications testing<\/li>\n<li>Keyless-entry system testing<\/li>\n<li>Wireless remote-control validation<\/li>\n<li>Filter frequency-response testing<\/li>\n<li>Amplifier gain characterization<\/li>\n<li>Antenna and cable-path testing<\/li>\n<li>Clock and local-oscillator generation<\/li>\n<li>Frequency hopping tests<\/li>\n<li>Bit-error-rate testing<\/li>\n<li>Automated production testing<\/li>\n<li>RF component characterization<\/li>\n<li>Laboratory research and automation<\/li>\n<\/ul>\n<h3>Receiver Sensitivity Testing<\/h3>\n<p>The PXI-5650 can apply a controlled RF signal to a receiver while software progressively reduces the output level. The test system monitors the receiver response to determine sensitivity, detection threshold or operating margin.<\/p>\n<p>Calibrate the complete RF path before relying on the programmed generator level. Cables, attenuators, switches and fixtures reduce the power reaching the receiver input.<\/p>\n<h3>Filter and Amplifier Testing<\/h3>\n<p>Frequency sweeps can characterize filters, amplifiers and other RF components. A compatible spectrum analyzer, vector signal analyzer or power sensor measures the device output at each programmed carrier frequency.<\/p>\n<p>These measurements can determine insertion loss, gain, passband ripple and cutoff behavior. Appropriate attenuation must be used when the device under test provides gain that could overload the receiving instrument.<\/p>\n<h3>Sub-GHz Wireless Device Testing<\/h3>\n<p>The 1.3 GHz upper frequency limit covers many industrial, scientific and medical bands as well as remote-control and keyless-entry applications. FM, FSK and OOK capabilities support functional testing of common low-data-rate receivers.<\/p>\n<p>Use a suitable RF shield enclosure when testing wireless products in production. Shielding reduces external interference and prevents the generated signal from affecting nearby equipment.<\/p>\n<h3>Automated Production Test<\/h3>\n<p>Software control allows the PXI-5650 to generate multiple frequencies, power levels and modulation conditions without manual adjustment. This improves repeatability and throughput in production test systems.<\/p>\n<p>The module can operate alongside PXI switches, analyzers, data-acquisition devices and digital interfaces. Test results can be automatically compared with limits and saved for product traceability.<\/p>\n<h3>NI-RFSG Software Support<\/h3>\n<p>The PXI-5650 is controlled through the NI-RFSG instrument driver. NI-RFSG provides functions for configuring carrier frequency, power level, modulation, configuration lists, reference clocks and triggers.<\/p>\n<p>The driver supports LabVIEW and compatible text-based programming environments. It also provides example applications and interactive controls for initial setup and troubleshooting.<\/p>\n<p>Because the PXI-5650 is discontinued, verify operating-system and development-environment compatibility with the specific NI-RFSG release used by the test station.<\/p>\n<h3>Pairing the PXI-5650 with an RF Analyzer<\/h3>\n<p>The generator can be used with a <a href=\"https:\/\/pxisource.com\/ru\/product\/pxi-5661\/\">PXI-5661 Vector Signal Analyzer<\/a> to create a modular RF stimulus-and-measurement system. Both instruments can share PXI timing resources and a common frequency reference.<\/p>\n<p>The PXI-5650 generates the CW or modulated signal, while the analyzer measures frequency, power, spectrum and modulation characteristics. This configuration supports automated component and receiver testing.<\/p>\n<h3>PXI Chassis Integration<\/h3>\n<p>The PXI-5650 occupies one 3U PXI slot. It can be installed in a compatible PXI chassis alongside switches, signal analyzers, digitizers and other test instruments.<\/p>\n<p>Before installation, verify chassis slot compatibility, cooling, controller support and NI-RFSG requirements. Always power down the chassis before inserting or removing the module.<\/p>\n<h3>PXI-5650 Troubleshooting<\/h3>\n<h4>The PXI-5650 is not detected in NI MAX<\/h4>\n<p>Confirm that the module is fully installed in a compatible PXI slot. Check chassis power, controller communication and NI-RFSG installation, then refresh the hardware list in NI Measurement &amp; Automation Explorer.<\/p>\n<h4>No RF signal appears at RF OUT<\/h4>\n<p>Verify that generation has started and RF output is enabled. Check the programmed frequency, power level, trigger configuration, cable and receiving instrument settings.<\/p>\n<h4>The measured output level is too low<\/h4>\n<p>Inspect the RF cable, adapters, attenuators and switches. Confirm that the requested output power is available at the selected frequency and that the measurement instrument uses a 50 \u03a9 input.<\/p>\n<h4>The generated frequency is incorrect<\/h4>\n<p>Check the frequency units entered by the application and review the reference-clock configuration. If an external reference is selected, confirm that a valid 10 MHz signal is connected.<\/p>\n<h4>The module does not lock to the external reference<\/h4>\n<p>Verify that the external reference is 10 MHz within the permitted tolerance and provides 0.2 Vpk-pk to 1.5 Vpk-pk into 50 \u03a9. Inspect the cable and allow enough time for the generator to acquire lock.<\/p>\n<h4>Frequency hopping is slower than expected<\/h4>\n<p>Use configuration lists and hardware triggers when possible. Overall speed also depends on the device under test, switching hardware, receiving instrument and application software.<\/p>\n<h4>FM or FSK modulation is distorted<\/h4>\n<p>Review the modulation rate, waveform and deviation settings. Confirm that the analyzer bandwidth captures the full modulated signal and that the selected parameters are supported at the configured carrier frequency.<\/p>\n<h4>The OOK timing is incorrect<\/h4>\n<p>Check the data source, trigger route and modulation timing. Use a suitable oscilloscope or RF analyzer to verify the carrier\u2019s on and off intervals.<\/p>\n<h4>The output contains excessive spurious signals<\/h4>\n<p>Allow the module to complete its warm-up period and verify calibration status. Check the external reference, shielding, grounding and nearby RF interference sources.<\/p>\n<h4>The module reports a PLL or thermal error<\/h4>\n<p>Confirm that chassis airflow is not blocked and that the ambient temperature remains within specification. Check the reference source and restart the generation session after the module returns to a valid operating temperature.<\/p>\n<h3>PXI-5650 Comparison with Related RF Signal Generators<\/h3>\n<table>\n<tbody>\n<tr>\n<th>\u041c\u043e\u0434\u0435\u043b\u044c<\/th>\n<th>Primary Configuration<\/th>\n<th>Best Suited For<\/th>\n<\/tr>\n<tr>\n<td>PXI-5650<\/td>\n<td>500 kHz to 1.3 GHz, FM, FSK and OOK<\/td>\n<td>Legacy PXI sub-GHz and IF signal generation<\/td>\n<\/tr>\n<tr>\n<td>PXI-5651<\/td>\n<td>500 kHz to 3.3 GHz, 12 dBm maximum output<\/td>\n<td>Legacy PXI RF testing through 3.3 GHz<\/td>\n<\/tr>\n<tr>\n<td>PXI-5652<\/td>\n<td>500 kHz to 6.6 GHz RF generation<\/td>\n<td>Higher-frequency legacy PXI systems<\/td>\n<\/tr>\n<tr>\n<td>PXIe-5650<\/td>\n<td>500 kHz to 1.3 GHz PXI Express generator<\/td>\n<td>PXI Express replacement for PXI-5650 applications<\/td>\n<\/tr>\n<tr>\n<td>PXIe-5651<\/td>\n<td>500 kHz to 3.3 GHz PXI Express generator<\/td>\n<td>Wireless and RF testing above 1.3 GHz<\/td>\n<\/tr>\n<tr>\n<td>PXIe-5654<\/td>\n<td>Up to 20 GHz with higher output power<\/td>\n<td>Modern RF and microwave component testing<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>PXI-5650 vs PXI-5651<\/h3>\n<p>The PXI-5650 and PXI-5651 provide similar CW, DDS, FM, FSK and OOK capabilities.
