The National Instruments PXI-2598 is a dual-transfer switch module designed for routing RF or microwave signals in automated test applications. While designed to operate with less than 1 dB insertion loss up to 26.5 GHz, the NI PXI-2598 appears almost invisible to signals at much lower frequencies as well. Use the PXI-2598 for basic signal routing or inserting and removing components in a signal path. This module is also well-suited for passing high-order harmonics from RF upconverters, such as the NI PXI-5670 2.7 GHz RF vector signal generator, or routing multiple sources to RF downconverters, such as the NI PXI-5660 2.7 GHz RF vector signal analyzer.

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.
