Overview and Applications
The National Instruments PXI-2596, PXI-2597, PXI-2598, and PXI-2599
multiplexers, SPDT relays, and transfer switch modules route RF or
microwave signals in automated test applications. While designed to
operate with less than 1 dB insertion loss up to 26.5 GHz, they appear
almost invisible to signals at much lower frequencies as well. Use the
NI PXI-2597 terminated multiplexer when high-power signal reflections are
a concern and 50 terminations are required. The PXI-2596 offers a
higher-density, unterminated option with dual 6x1 multiplexer banks in the
same module. The PXI-2598 and PXI-2599 operate as transfer switches and
SPDT relays, respectively, for basic signal routing or inserting and
removing components in a signal path. These modules are 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.
Software
All National Instruments PXI switch modules are shipped with NI-SWITCH,
an IVI-compliant driver offering complete functionality for all switch
modules. For additional assistance in configuring, programming, and
managing higher-channel-count switching systems, NI Switch Executive
software offers an easy-to-use, intelligent switch management and visual
routing environment. With the latest version of NI Switch Executive, you
can store calibration information for your RF/microwave switch routes on a
per-path basis. Use the NI-SWITCH Soft Front Panel for simple relay
operations or debugging switch code/execution.

Relay Count Tracking
The switches count relay closures on each of their individual relays.
Relay counts are incremented each time a relay is actuated. You can
programmatically retrieve the counts, stored on board the modules, and use
them for predictive maintenance to reduce unexpected system downtime.

Signal Connectivity Options
The PXI-2596, PXI-2597, PXI-2598, and PXI-2599 all use standard SMA
connectors for signal connections. National Instruments offers two semirigid
SMA cables (0.15 and 0.45 cm) that are acceptable for many RF/microwave
signals. There are also many custom cable vendors on the market that can
meet your exact cable length, performance, and connector requirements.
