Description
The product with the part number 778572-57 falls under the category of PXI Switches. It is specifically the PXI-2557 model, which is described as a 2.5 GHz 75 Ohm 8X1 Multiplexer. This device is a type of PXI RF Multiplexer Switch Module and is recognized for its high channel count. It is primarily designed for the application of switching of a large number of video RF signals, including the capability to switch multiple video tuners under test to a single channel on the RF analyzer.
The PXI-2557 has an insertion loss that is analogous to a 3 dB graph (Bode plot) for a lowpass filter, indicating its efficiency in signal transmission with minimal loss. Another critical specification is its VSWR (Voltage Standing Wave Ratio), which is the ratio of reflected to transmitted waves. This specification is particularly important in RF applications to prevent energy loss and damage to the source due to signal reflections, ensuring a high-quality and reliable performance in critical applications.
