The National Instruments PXI-2594 is a 4x1 high-frequency unterminated multiplexing switch capable of switching signals from DC to 2.5 GHz. The characteristic impedance of the channels on this module is 50 Ω. The NI PXI-2594 has a maximum voltage rating of 30 Vrms with a maximum switching current of 500 mA. It is well-suited for applications that require the routing of high-frequency signals inside automated test equipment (ATE) systems because it can switch signals with very low insertion loss. In addition, the excellent voltage standing-wave ratio (VSWR) and isolation parameters make this module the perfect choice in any system geared toward high-frequency applications. The PXI-2594 also offers relay count tracking to help reduce unexpected system downtime.

Note: The bandwidth specification of a switch module is not an absolute specification and is determined by vendor standards. Although higher frequency signals can be routed through this switch module, they will encounter more degradation than those at lower frequencies. In order to determine the best switch module for your application review the insertion loss, VSWR, and isolation specifications of the product for the bandwidth of your application. For more information on choosing the right RF switch for your application, review the ‘Guide to Selecting and RF Switch’ linked in the 'Resources' section of this page.

System Assurance Programs

Reduce your setup time and total cost of ownership, and get a system you can use out of the box with National Instruments system assurance programs. System assurance programs include:

  • Installation and integration test of all individual hardware
  • Courtesy installation of system driver sets and application development environments
  • Three-year warranty and calibration coverage
  • Custom documentation plus a custom restore and startup utility

This service is only available for PXI, NI CompactRIO, and NI Compact FieldPoint systems.

Extended Warranties

National Instruments designs and manufactures all products to minimize failures, however unexpected failures can still occur. Extended warranties provide a fixed economical price at the time of system purchase, covering any repair costs for up to three years. In addition, they offer the following benefits:

  • Significant cost savings compared to individual repair incidents
  • Fault location, diagnostics, and repair by NI any time the system product fails
  • All parts and labor costs covered as well as any adjustments needed to restore the hardware to manufacturing specifications

For more information about your warranty options:

Calibration

NI recognizes the need to maintain properly calibrated devices for high-accuracy measurements. NI provides manual calibration procedures, services to recalibrate your products, and automated calibration software to calibrate many NI measurement products.

Training

NI training is the fastest, most certain route to productivity with NI tools and successful application development.

Repair Services

Return your registered product under warranty at no additional labor and parts cost. NI offers fault location, diagnostics, and repair any time the system fails as well as any adjustments needed to restore the hardware to manufacturing specifications.
