A system requiring access to all analog-output and digital channels may need two compatible cables and terminal accessories. Verify the cable pinout, connector-block compatibility, cable length and required accessory quantity before ordering.<\/p>\n<h3>64-Channel Analog Output Architecture<\/h3>\n<p>The PXIe-6739 provides 64 programmable voltage-output channels in a single PXI Express module. Its high channel density helps reduce the number of modules and chassis slots required in systems that need many independent analog stimulus signals.<\/p>\n<p>The outputs can simulate sensor voltages, provide controller setpoints, generate reference signals and stimulate analog inputs on a device under test. Each connected load must remain within the module\u2019s voltage and current-drive specifications.<\/p>\n<h3>Understanding the 16 DAC Banks<\/h3>\n<p>The module\u2019s 64 analog outputs are organized into 16 DAC banks, with four channels assigned to each bank. Channels within the same bank are updated simultaneously through a shared digital-to-analog converter.<\/p>\n<p>This architecture affects the maximum update rate. Applications requiring 16 outputs at 1 MS\/s should select one channel from each separate DAC bank. If multiple channels are selected from the same bank, the available update performance changes according to the number of channels sharing that DAC.<\/p>\n<p>Review the official PXIe-6739 channel-to-bank mapping before assigning timing-critical signals. Careful channel allocation can improve update performance without requiring additional modules.<\/p>\n<h3>Analog Output Update Rates<\/h3>\n<p>The PXIe-6739 has a maximum analog update rate of 1 MS\/s. However, this does not mean that all 64 channels can update independently at 1 MS\/s.<\/p>\n<table>\n<tbody>\n<tr>\n<th>Active Outputs<\/th>\n<th>Maximum Update Rate<\/th>\n<th>\u041a\u043e\u043d\u0444\u0438\u0433\u0443\u0440\u0430\u0446\u0438\u044f<\/th>\n<\/tr>\n<tr>\n<td>One channel<\/td>\n<td>1 MS\/s<\/td>\n<td>Single active analog output<\/td>\n<\/tr>\n<tr>\n<td>Up to 16 channels<\/td>\n<td>1 MS\/s<\/td>\n<td>One active channel from each DAC bank<\/td>\n<\/tr>\n<tr>\n<td>All 64 channels<\/td>\n<td>350 kS\/s<\/td>\n<td>All four channels in every DAC bank<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Software and test-system timing should be designed around the number and physical bank location of the enabled outputs. This distinction is especially important in hardware-in-the-loop and dynamic waveform-generation applications.<\/p>\n<h3>16-Bit Output Resolution<\/h3>\n<p>The PXIe-6739 provides 16-bit output resolution, dividing the programmed voltage span into 65,536 discrete levels. This fine resolution supports sensor simulation, programmable setpoints and applications requiring small voltage changes.<\/p>\n<p>Output resolution should not be confused with absolute accuracy. The final voltage at the device under test can also be affected by calibration, connected load, cable resistance, grounding, external noise and temperature.<\/p>\n<h3>\u00b110 V Output Range<\/h3>\n<p>Each analog-output channel supports a bipolar \u00b110 V range. This widely used instrumentation range is suitable for stimulating data acquisition devices, industrial controllers, electronic control units and other analog interfaces.<\/p>\n<p>The outputs are DC coupled and can generate fixed DC levels, steps, ramps and continuously updated waveform sequences. Verify the allowable input range of the device under test before enabling the output task.<\/p>\n<h3>\u00b110 mA Output Drive<\/h3>\n<p>Each PXIe-6739 output can source or sink up to 10 mA while operating within specification. The module can provide its specified 10 V and 10 mA output capability across all 64 channels simultaneously when every connected load meets the required electrical conditions.<\/p>\n<p>A 10 V signal delivering 10 mA corresponds to a load of approximately 1 k\u03a9. Loads with lower resistance may require more current than the output can supply. Use an appropriate external buffer or power amplifier when additional current is required.<\/p>\n<h3>Output Impedance and Protection<\/h3>\n<p>The analog outputs have a specified output impedance of 0.2 \u03a9. Low output impedance helps reduce voltage changes caused by variations in the external load.<\/p>\n<p>The module provides overdrive protection up to \u00b115 V. This protection improves resistance to limited abnormal conditions but does not replace external fuses, current limiting, transient suppression or electrical isolation.<\/p>\n<h3>20 Digital I\/O Lines<\/h3>\n<p>The PXIe-6739 includes 20 bidirectional digital I\/O lines using 5 V TTL logic. These lines can control test-fixture relays, monitor device states, create handshaking signals or coordinate analog generation with external equipment.<\/p>\n<p>Confirm that every connected digital device uses compatible logic levels. Industrial-voltage signals require suitable external interface, protection or isolation circuitry.<\/p>\n<h3>Four Counter\/Timers<\/h3>\n<p>Four general-purpose counter\/timers support operations such as event counting, pulse generation, frequency measurement and timing control. These resources can eliminate the need for a separate counter module in many test systems.<\/p>\n<p>The counters can also be combined with digital triggering and analog-output generation to coordinate stimulus signals with external events.<\/p>\n<h3>Digital Triggering<\/h3>\n<p>Digital triggering allows an analog-output task to start or change state in response to a defined hardware event. Hardware triggering generally provides more repeatable timing than relying exclusively on software commands.<\/p>\n<p>The module can be synchronized with external devices and compatible PXI instruments through available trigger and timing resources. Verify trigger polarity, routing and timing requirements during system configuration.<\/p>\n<h3>PXI Express Synchronization<\/h3>\n<p>The PXIe-6739 can use PXI Express timing and trigger resources to coordinate its outputs with digitizers, digital instruments, data acquisition modules and other waveform-generation hardware.<\/p>\n<p>This synchronization is valuable in stimulus-response systems because the generated stimulus and acquired response can maintain a defined timing relationship. Multiple modules can also be synchronized when more than 64 output channels are required.<\/p>\n<h3>Open-Loop Simulation<\/h3>\n<p>Open-loop simulation systems generate electrical signals that represent sensors, commands or environmental conditions without calculating a real-time response from the device under test. The PXIe-6739 can generate many analog signals while its digital I\/O and counters provide supporting control functions.<\/p>\n<p>Typical examples include simulating temperature, pressure, position and command-voltage signals. External signal conditioning may be required when an interface uses current, resistance, frequency or voltage levels outside the PXIe-6739 specifications.<\/p>\n<h3>Hardware-in-the-Loop Testing<\/h3>\n<p>The PXIe-6739 is suitable for HIL systems that require many simulated sensor and command signals. A real-time controller can update its analog outputs based on a simulation model while other PXI modules acquire the response from the controller under test.<\/p>\n<p>For deterministic applications, evaluate the required loop rate, number of outputs, DAC-bank assignment and overall system latency. Systems using all 64 channels should account for the 350 kS\/s maximum full-channel update rate.<\/p>\n<h3>Stimulus-Response Testing<\/h3>\n<p>In stimulus-response testing, the PXIe-6739 applies known voltage levels or waveforms to a device under test. Other PXI instruments then measure the resulting analog, digital or communication response.<\/p>\n<p>Automating both generation and measurement makes it possible to repeat test conditions, sweep operating points and verify electronic behavior across many channels without manual signal adjustments.<\/p>\n<h3>Multichannel Waveform Generation<\/h3>\n<p>The module can generate DC levels, steps, ramps, periodic waveforms and arbitrary sample sequences. Waveform data can be generated programmatically or loaded from stored test data through NI-DAQmx.<\/p>\n<p>When phase alignment and update timing are important, account for the shared DAC-bank architecture. Channels in the same bank update simultaneously, while one channel from each bank can be used to achieve 16-channel operation at 1 MS\/s.<\/p>\n<h3>Production Test Applications<\/h3>\n<p>Production systems can use the PXIe-6739 to apply programmable voltages to circuit boards, control units and electronic assemblies. Test software can change the output conditions automatically without requiring manual adjustment of external voltage sources.<\/p>\n<p>Its 64-channel density is especially useful in fixtures containing many analog inputs. The module can be combined with PXI measurement hardware to create a compact stimulus-and-measurement platform.<\/p>\n<h3>NI-DAQmx Software Support<\/h3>\n<p>The PXIe-6739 is controlled through the NI-DAQmx driver. NI-DAQmx provides functions for channel configuration, waveform writing, sample timing, triggering, digital I\/O and counter operations.<\/p>\n<p>The driver supports integration with LabVIEW, LabWindows\/CVI, C\/C++, Python and other compatible programming environments. NI Measurement &amp; Automation Explorer can detect the module, run self-tests and provide basic configuration tools.<\/p>\n<h3>LabVIEW Integration<\/h3>\n<p>LabVIEW applications can create analog-output tasks, generate waveform buffers and coordinate the PXIe-6739 with measurement instruments. Hardware timing and trigger routing can be used when a test requires repeatable signal generation.<\/p>\n<p>For high-channel-count applications, organize the software configuration according to the module\u2019s 16 DAC banks. This helps developers understand the available update rate and simultaneous-update behavior.<\/p>\n<h3>PXI-6723 Upgrade Adapter<\/h3>\n<p>The PXIe-6739 adapter, part number 783803-01, attaches to the module\u2019s front panel and adapts its pinout for compatibility with SH68-C68-S cables previously installed for the PXI-6723.<\/p>\n<p>This adapter can reduce rewiring when modernizing a legacy PXI-6723 system. Engineers should still verify software compatibility, channel mapping, output specifications and test-program assumptions before completing the upgrade.<\/p>\n<h3>Typical PXIe-6739 Applications<\/h3>\n<ul>\n<li>High-density analog stimulus generation<\/li>\n<li>Open-loop simulation<\/li>\n<li>Hardware-in-the-loop testing<\/li>\n<li>Stimulus-response validation<\/li>\n<li>Sensor voltage simulation<\/li>\n<li>Automotive controller testing<\/li>\n<li>Aerospace electronics validation<\/li>\n<li>Industrial controller testing<\/li>\n<li>Production functional testing<\/li>\n<li>Multichannel waveform generation<\/li>\n<li>Programmable setpoint control<\/li>\n<li>Laboratory automation<\/li>\n<li>Device characterization<\/li>\n<li>Research instrumentation<\/li>\n<\/ul>\n<h3>PXIe-6739 Troubleshooting<\/h3>\n<h4>The module is not detected in NI MAX<\/h4>\n<p>Confirm that the PXIe-6739 is fully installed in a compatible PXI Express slot. Check chassis power, controller communication and the installed NI-DAQmx version. Restart the chassis and rescan the system in NI Measurement &amp; Automation Explorer.<\/p>\n<h4>The output does not reach the programmed voltage<\/h4>\n<p>Measure the connected load and calculate the required current. A load demanding more than \u00b110 mA can prevent the output from reaching the requested voltage. Inspect the cable, terminal block, grounding and fixture wiring for excessive loading or short circuits.<\/p>\n<h4>All 64 channels cannot update at 1 MS\/s<\/h4>\n<p>The 1 MS\/s specification applies to one channel or up to 16 channels when one output is selected from each DAC bank. The specified maximum update rate with all 64 outputs active is 350 kS\/s.<\/p>\n<h4>Sixteen channels do not reach 1 MS\/s<\/h4>\n<p>Verify that the selected channels are distributed one per DAC bank. Selecting multiple outputs from the same bank changes the applicable update-rate configuration.<\/p>\n<h4>Several outputs change simultaneously<\/h4>\n<p>Each DAC bank controls four analog-output channels. Channels assigned to the same bank are designed to update simultaneously. Review the channel-to-bank mapping when assigning independent stimulus signals.<\/p>\n<h4>The generated waveform contains noise<\/h4>\n<p>Check cable shielding, terminal connections, grounding and the relationship between the chassis ground and device-under-test ground. Keep analog wiring away from motors, relays, switching power supplies and high-current conductors.<\/p>\n<h4>A digital line does not operate correctly<\/h4>\n<p>Confirm that the line direction and NI-DAQmx configuration are correct. Verify that the external device uses compatible 5 V TTL levels and that the two systems share the required ground reference.<\/p>\n<h4>The load requires more than 10 mA<\/h4>\n<p>Use an external voltage buffer or power amplifier with sufficient voltage range, current capacity, bandwidth and protection. Do not parallel analog-output channels unless a properly engineered external circuit explicitly supports it.<\/p>\n<h3>PXIe-6739 Comparison with Related Analog Output Modules<\/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>PXIe-6739<\/td>\n<td>64 channels, 16-bit, up to 1 MS\/s<\/td>\n<td>High-density PXI Express analog stimulus<\/td>\n<\/tr>\n<tr>\n<td>PXIe-6738<\/td>\n<td>32-channel PXI Express analog output<\/td>\n<td>Systems requiring fewer analog outputs<\/td>\n<\/tr>\n<tr>\n<td>PXI-6723<\/td>\n<td>Legacy high-density PXI analog output<\/td>\n<td>Maintaining existing PXI systems and fixtures<\/td>\n<\/tr>\n<tr>\n<td>PXI-6733<\/td>\n<td>Lower-channel-count high-speed analog output<\/td>\n<td>Applications prioritizing fewer waveform channels<\/td>\n<\/tr>\n<tr>\n<td>PXI-6713<\/td>\n<td>Legacy analog waveform output module<\/td>\n<td>Supporting established PXI generation systems<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>PXIe-6739 vs PXIe-6738<\/h3>\n<p>The PXIe-6739 provides 64 analog outputs, while the PXIe-6738 provides a lower channel count.
