Overview and Applications
NI SCXI-1193
NI 2593
Unterminated
Multiplexer
Topology
NI PXI-2593, PXIe-2593, and SCXI-1193 are high-density 50 Ω RF relay modules.
You can programmatically configure them as unterminated multiplexers,
externally terminated multiplexers, or dimensionally flexible sparse matrices.
Each configuration handles signal frequencies from DC to beyond 500 MHz.
These single-slot switch modules use high-density push-on MCX connectors
for discrete yet manageable cabling. NI 2593 modules are designed to integrate
with high-frequency instruments such as the NI PXI-5404 frequency generator
and the NI PXI-5112 high-speed digitizer.

Table 1. This table shows available multiplexer configurations.
Dimensionally Flexible Sparse Matrix Configurations
You can configure the NI 2593 modules as flexible sparse matrices, which
you can use to route signals between any pair of channels or commons
while maintaining >500 MHz bandwidth and minimizing reflections. Unlike a
traditional sparse matrix made from two multiplexers with their COM terminals
connected, these modules use a flexible architecture in which you can define
the row and column dimensions. There is no restriction on row-to-row or
column-to-column connections. For example, you can configure the 18 terminals
on the NI 2593 modules as a 2x16, 4x14, or 9x9 sparse matrix, or any size in
between. It is even possible to connect multiple crosspoints simultaneously.
Figure 1 demonstrates the configuration capabilities of an NI 2593 as a
dimensionally flexible sparse matrix.
Multiplexer Configurations
The NI 2593 and SCXI-1193 are 16- and 32-channel unterminated multiplexers,
respectively. With external 50 Ω MCX terminators (P/N: 761930-01) on half of
the channels, you can use these modules as terminated multiplexers. Table 1
shows multiplexer configurations for each module.
High-Frequency Multiplexer/Matrix Modules
System Integration
Ordering Information
The NI 2593 modules have a flexible scan list architecture that can reduce
overall data acquisition and test time. A scan list delivers the fastest scan
possible by providing a hardware-timed solution. You can configure the module
to process the scan list once or to continuously loop through the scan list.
Commands in the scan list can open or close relays, wait for an external trigger,
and generate a scanner advanced trigger. The external trigger, sourced by
an instrument, such as an NI PXI-5411 arbitrary waveform generator, causes
the switch module to advance to the next entry in the scan list. The scanner
advanced trigger indicates when the module has closed all specified relays
and the relays have settled. The scanner advanced trigger is typically connected
to a measurement device, such as the NI PXI-4070 FlexDMM, which is
configured to take a reading upon receiving the trigger.

System Assurance Programs
NI system assurance programs are designed to make it even easier for you
to own an NI system. These programs include configuration and deployment
services for your NI PXI, CompactRIO, or Compact FieldPoint system. The NI Basic
System Assurance Program provides a simple integration test and ensures that
your system is delivered completely assembled in one box. When you configure
your system with the NI Standard System Assurance Program, you can select
from available NI system driver sets and application development environments
to create customized, reorderable software configurations. Your system arrives
fully assembled and tested in one box with your software preinstalled. When
you order your system with the standard program, you also receive system-
specific documentation including a bill of materials, an integration test report,
a recommended maintenance plan, and frequently asked question documents.
Finally, the standard program reduces the total cost of owning an NI system
by providing three years of warranty coverage and calibration service. Use the
online product advisors at ni.com/advisor to find a system assurance program
to meet your needs.
