National Instruments PXIe-2748 PXI RF Multiplexer Switch Module

The PXIe-2748 (Part Number: 780587-48) is a 16x1 PXI RF Multiplexer Switch Module that is well-suited for switching RF signals up to 3 GHz in production test applications. The massive channel count of the NI PXIe-2748 makes it well-suited for test systems that necessitate switching many RF signals, such as switching multiple devices under test to a single channel on an RF analyzer. The PXIe-2748 has an onboard relay counting feature that monitors relays. This module is great for applications that need to link measurement or signal generation instruments to various test points on devices or units under test (DUTs or UUTs).

All input characteristics of the NI PXIe-2748 PXI RF Multiplexer Switch Module are DC, AC_rms, or a combination of both. The maximum switching voltage is 30 V, maximum RF power is 10 W, maximum switching current is 0.5 A, and the maximum carry current per channel is 0.5 A. The power requirement for this module is 3.96 W at 3.3 V, 0.2 W at 12 V.

The PXIe-2748 module has a relative humidity range of 5% to 95% (noncondensing), and should be stored at a temperature ranging from -40 ⁰ C to 70 ⁰ C. Its random vibration while operating/non-operating is between 5 Hz and 500 Hz, 0.3 g_rms and 5 Hz and 500 Hz, 2.4 g_rms. The dimensions for this module are 8.5 in. x 0.8 in. x 5.1 in.  and it weighs 11.30 oz.
