Overview
Switches
The National Instruments PXI-2590 and PXI-2591 are 4x1 highfrequency unterminated multiplexing switches. The NI SCXI-1190 and
NI SCXI-1191 perform the same functions as the PXI-2590 and
PXI-2591 but also offer a quad 4x1 multiplexing configuration. The
switches are capable of switching signals from DC to 1.3 GHz
(SCXI-1190 and PXI-2590) and DC to 4 GHz (SCXI-1191 and
PXI-2591). The characteristic impedance of the channels is 50 .
For the SCXI-1190 and the PXI-2590, the maximum voltage rating
of the switches is 24 Vrms with a maximum current of 1 A. For the
SCXI-1191 and the PXI-2591, the maximum voltage rating is 30 Vrms
with a maximum current of 330 mA. All are well suited for
applications that require the routing of high-frequency signals inside
automated test equipment (ATE) systems because they can switch
signals with a very low insertion loss. In addition, the excellent
voltage standing-wave ratio (VSWR) and isolation parameters make
these modules the perfect choice in a system geared to highfrequency applications as shown in Table 1.
