Use properly rated 50 \u03a9 RF cables and follow the recommended SMA connector torque to preserve repeatable high-frequency performance.<\/p>\n<h3>4\u00d71 RF Multiplexer Architecture<\/h3>\n<p>The PXI-2595 contains a single 4\u00d71 multiplexer. Software can connect any one of four RF channels to the common port, allowing several signal sources or devices under test to share one RF instrument.<\/p>\n<p>A typical configuration connects the common port to a spectrum analyzer, RF digitizer, signal generator, receiver or other 50 \u03a9 instrument. The four selectable channels can connect to separate devices, antennas, test points or fixture paths.<\/p>\n<p>The multiplexer is normally configured with only one active channel connected to the common port. Engineers should prevent conflicting sources from being connected together and verify that all signals remain within the voltage, current and RF power ratings.<\/p>\n<h3>DC to 5 GHz RF Signal Routing<\/h3>\n<p>The PXI-2595 can route signals from DC through 5 GHz. This broad operating range supports baseband, intermediate-frequency and RF signals within a single programmable switching module.<\/p>\n<p>Typical applications include communications-device testing, RF component characterization, receiver and transmitter validation, automated production testing and general-purpose laboratory signal routing.<\/p>\n<p>The bandwidth of the complete test system also depends on the cables, connectors, adapters, fixtures and connected instruments. Every component should be selected for the required frequency range and 50 \u03a9 impedance.<\/p>\n<h3>50 \u03a9 Characteristic Impedance<\/h3>\n<p>The PXI-2595 is designed for 50 \u03a9 RF test systems. This impedance is widely used by signal generators, spectrum analyzers, network analyzers, digitizers and wireless communications equipment.<\/p>\n<p>Maintaining consistent 50 \u03a9 impedance helps reduce reflections, mismatch loss and standing waves. Avoid mixing 50 \u03a9 and 75 \u03a9 cables or terminations unless the system includes a suitable impedance-matching network.<\/p>\n<h3>Insertion Loss Performance<\/h3>\n<p>The PXI-2595 specifies insertion loss below 0.7 dB through 1 GHz, below 1.7 dB through 3 GHz and below 2.8 dB through 5 GHz. Its typical insertion loss is lower under representative operating conditions.<\/p>\n<p>Insertion loss increases with frequency and is also affected by external cables and adapters. For accurate amplitude measurements, characterize the complete path and apply path-loss compensation in the measurement software when necessary.<\/p>\n<h3>RF Isolation Performance<\/h3>\n<p>Channel isolation is greater than 70 dB through 1 GHz, greater than 55 dB through 3 GHz and greater than 30 dB through 5 GHz. High isolation helps prevent energy on unselected channels from reaching the active measurement path.<\/p>\n<p>System isolation can be reduced by poorly shielded cables, external fixture coupling, damaged connectors and improper grounding. Keep high-power sources physically separated from sensitive receiver paths.<\/p>\n<h3>VSWR and Signal Integrity<\/h3>\n<p>The PXI-2595 provides controlled VSWR performance across its frequency range. Maximum VSWR is below 1.25 through 1 GHz, below 1.40 through 3 GHz and below 1.85 through 5 GHz.<\/p>\n<p>Good VSWR helps reduce signal reflections when the switch is used with matched 50 \u03a9 equipment. Actual system performance should be evaluated with the final cables, adapters, fixtures and instruments installed.<\/p>\n<h3>Unterminated RF Architecture<\/h3>\n<p>The PXI-2595 is an unterminated multiplexer. When a channel is not selected, it is not automatically connected to an internal 50 \u03a9 termination.<\/p>\n<p>If an RF source requires a defined load while disconnected, install an appropriate external termination or select a switch architecture with internal termination. This is especially important when open-channel reflections could affect the source or test result.<\/p>\n<h3>10 W RF Switching Capability<\/h3>\n<p>The maximum channel-to-common RF switching power is 10 W. The signal must also remain within the 30 V maximum switching voltage and 0.5 A maximum switching-current ratings.<\/p>\n<p>The usable RF power can depend on frequency, impedance match and switching conditions. Confirm all simultaneous electrical limits instead of evaluating only the 10 W rating.<\/p>\n<h3>Cold Switching and Relay Protection<\/h3>\n<p>For maximum relay life and repeatable RF performance, remove or reduce RF power before changing routes whenever the test sequence permits. This practice is commonly referred to as cold switching.<\/p>\n<p>Switching active RF signals can stress relay contacts, degrade signal integrity and shorten electrical life. The module should not be treated as protection against excessive source power or unexpected RF transients.<\/p>\n<h3>Electromechanical Latching Relays<\/h3>\n<p>The PXI-2595 uses electromechanical latching relays. These relays provide broadband signal routing that extends to DC and maintain their selected state without continuously energizing the relay coil.<\/p>\n<p>Relay contacts have a finite operating life. The expected mechanical life is one million cycles, while electrical life depends on the switched voltage, current, power, load type and switching conditions.<\/p>\n<h3>Relay-Count Tracking<\/h3>\n<p>Onboard relay-count tracking records switching activity for the module\u2019s relays. Maintenance teams can use this information to identify heavily used channels and estimate when preventive service may be required.<\/p>\n<p>Where the fixture architecture permits, engineers can distribute frequently used routes across different channels to balance relay usage and reduce unexpected test-system downtime.<\/p>\n<h3>Low Timing Skew and Propagation Delay<\/h3>\n<p>The PXI-2595 provides less than 1 ps typical channel-to-channel skew and less than 700 ps typical propagation delay. Typical signal rise time is less than 65 ps.<\/p>\n<p>These characteristics support high-frequency signal routing where consistent electrical path length is important. External cable length and fixture geometry can introduce substantially more skew than the switch itself, so matched cables may be required.<\/p>\n<h3>Hardware Triggering and Scanning<\/h3>\n<p>The module supports PXI hardware triggering for coordinated route changes in automated test systems. Hardware triggers can synchronize the switch with RF sources, digitizers and other PXI instruments.<\/p>\n<p>The PXI-2595 provides a maximum scan rate of 45 channels per second and a maximum relay operating time of 10.4 ms. Test software should also include any settling time required by the signal source, DUT and measurement instrument.<\/p>\n<h3>Typical PXI-2595 Applications<\/h3>\n<ul>\n<li>Automated RF test equipment<\/li>\n<li>Wireless communications testing<\/li>\n<li>RF source selection<\/li>\n<li>Spectrum analyzer input selection<\/li>\n<li>RF digitizer signal routing<\/li>\n<li>Receiver and transmitter validation<\/li>\n<li>RF component characterization<\/li>\n<li>Antenna-path selection<\/li>\n<li>Production functional testing<\/li>\n<li>Research and laboratory automation<\/li>\n<li>Broadband signal routing<\/li>\n<li>Multipoint RF measurements<\/li>\n<\/ul>\n<h3>Automated RF Test Systems<\/h3>\n<p>In an automated test system, the PXI-2595 can connect several RF paths to one expensive measurement instrument. Software selects the required device or test point before triggering the measurement.<\/p>\n<p>This architecture reduces manual cable changes and improves instrument utilization. Multiple switch modules can be installed when the system requires additional channels or separate switching banks.<\/p>\n<h3>Wireless Device Validation<\/h3>\n<p>The module can route RF signals during the validation of radios, receivers, transmitters and wireless components operating below 5 GHz. Test software can select different device outputs, stimulus paths or antenna connections.<\/p>\n<p>For transmitter testing, confirm that the maximum output power and transient behavior remain within the PXI-2595 ratings. External attenuators, directional couplers or protection components may be required for higher-power transmitters.<\/p>\n<h3>RF Instrument Sharing<\/h3>\n<p>The 4\u00d71 configuration allows four DUT connections to share one spectrum analyzer, digitizer or receiver. Alternatively, four RF sources can be selected sequentially and routed to one device under test.<\/p>\n<p>Before switching between sources, configure inactive sources appropriately and prevent them from driving unterminated channels when that condition could cause instability or excessive reflection.<\/p>\n<h3>SMA Connector Integration<\/h3>\n<p>The five front-panel SMA connectors provide direct compatibility with common 50 \u03a9 RF cables and instruments. Use quality cables with the required bandwidth and avoid unnecessary adapters.<\/p>\n<p>Inspect connectors before installation and keep them free of contamination. Excessive or insufficient connector torque can damage the interface or produce inconsistent RF measurements.<\/p>\n<h3>NI-SWITCH Software Support<\/h3>\n<p>The PXI-2595 is controlled through the NI-SWITCH instrument driver. NI-SWITCH provides functions for initializing the module, connecting and disconnecting channels, creating scan lists, configuring triggers and reading relay-count information.<\/p>\n<p>The driver supports integration with LabVIEW, LabWindows\/CVI and compatible text-based programming environments. Route control can be included directly within an automated RF measurement sequence.<\/p>\n<h3>NI Switch Executive Integration<\/h3>\n<p>NI Switch Executive allows users to define signal paths with descriptive route names instead of controlling physical relays directly. This can make applications easier to develop and maintain.<\/p>\n<p>Named routes are especially useful in systems containing multiple switch modules and complex test fixtures. Hardware changes can often be managed within route configuration without rewriting the complete test application.<\/p>\n<h3>PXI Chassis Integration<\/h3>\n<p>The PXI-2595 occupies one slot in a compatible 3U PXI chassis. It can be installed alongside RF signal generators, digitizers, controllers and other PXI measurement modules.<\/p>\n<p>Before installation, verify chassis compatibility, slot availability, controller communication and NI-SWITCH software support. Provide adequate clearance for the five SMA cables and avoid excessive mechanical stress on the front-panel connectors.<\/p>\n<h3>PXI-2595 Troubleshooting<\/h3>\n<h4>The PXI-2595 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 the NI-SWITCH driver installation, then restart NI Measurement &amp; Automation Explorer.<\/p>\n<h4>No Signal Appears at the Common Port<\/h4>\n<p>Verify that the correct channel-to-common route is closed. Check the RF source, cable continuity, SMA connector engagement and receiving-instrument configuration.<\/p>\n<h4>Insertion Loss Is Higher Than Expected<\/h4>\n<p>Inspect the cables, connectors and adapters for damage or contamination. Confirm that every component supports 50 \u03a9 operation and the required frequency. Measure and compensate for the complete path loss when necessary.<\/p>\n<h4>VSWR Is Excessive<\/h4>\n<p>Verify that the source, load, cables and termination components all use 50 \u03a9 impedance. Remove unnecessary adapters and check SMA connector torque. Add an external termination if an unused source requires a defined load.<\/p>\n<h4>Signals Leak Between Channels<\/h4>\n<p>Check fixture shielding, cable routing and grounding. Separate strong RF sources from sensitive receiver paths and inspect the external wiring for unintended coupling between channels.<\/p>\n<h4>A Relay Does Not Change State<\/h4>\n<p>Verify the commanded route and review the relay-count information. Disconnect external signals and test the channel with a known low-level source. A heavily used or overstressed relay may require service.<\/p>\n<h4>Relay Life Is Shorter Than Expected<\/h4>\n<p>Check whether routes are being changed while RF power is present. Verify the source voltage, current and power, and use cold switching whenever possible. Also check for capacitive discharge and transient energy.<\/p>\n<h4>High-Frequency Measurements Are Not Repeatable<\/h4>\n<p>Use phase-stable RF cables, avoid moving cables during measurements and allow sufficient settling time after switching. Calibrate the system with the switch and external signal path in their final configuration.<\/p>\n<h3>PXI-2595 Comparison with Similar RF Switch 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>PXI-2594<\/td>\n<td>2.5 GHz, 50 \u03a9, 4\u00d71 multiplexer<\/td>\n<td>Lower-frequency 4\u00d71 RF routing<\/td>\n<\/tr>\n<tr>\n<td>PXI-2595<\/td>\n<td>5 GHz, 50 \u03a9, unterminated 4\u00d71 multiplexer<\/td>\n<td>General-purpose RF routing through 5 GHz<\/td>\n<\/tr>\n<tr>\n<td>PXI-2596<\/td>\n<td>26.5 GHz, dual 6\u00d71 multiplexer<\/td>\n<td>High-frequency and microwave routing with greater density<\/td>\n<\/tr>\n<tr>\n<td>\u041f\u0425\u0418-2597<\/td>\n<td>26.5 GHz, 50 \u03a9, terminated 6\u00d71 multiplexer<\/td>\n<td>Microwave routing requiring internal termination<\/td>\n<\/tr>\n<tr>\n<td>PXI-2598<\/td>\n<td>26.5 GHz transfer-switch architecture<\/td>\n<td>High-frequency transfer and insert-bypass routing<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>PXI-2595 vs PXI-2594<\/h3>\n<p>\u0417\u0435\u043c\u043b\u044f <a href=\"https:\/\/pxisource.com\/ru\/product\/pxi-2594\/\">PXI-2594<\/a> and PXI-2595 both provide a 50 \u03a9, 4\u00d71 RF multiplexer topology.
