R&S®FSU-U73-B73 Vector signal analysis for FSU, 7 MHz demodulation bandwidth, demodulation hardware included

Overview

Key Facts

Specifications

Specified frequency range	20 MHz to max frequency of analyzer
Max symbol rate	6.4 MHz
IQ bandwidth	7 MHz

Key Facts

The general vector signal analysis function is available now for R&S^® FSU. The option R&S^® FSU-B73 gives a narrowband, cost effective VSA solution. It contains the necessary hardware and the K70 well known from Signal analyzer R&S^® FSQ. The option R&S^® FSU-B73 is not retrofittable.
The option R&S FSU-U73 is for retrofit of XP units (requires FW version 4.0 or higher). Functionality and user interface of VSA option is identical to FSQ-K70. Please refer to FSQ-K70 for manuals or more detailed information.

All options are available at standard delivery. Specifications are covered in a combined specification data sheet for R&S^® FSQ-K70, R&S^® FSU-B73 and R&S^® FSMR-B73.
