Anritsu Option 400, Enable Vision Monitor
The MS27201A-0400 is Option 90, Gated Sweep, for the Anritsu MS27201A Remote Spectrum Monitor. This option enables the Gated Sweep measurement function, which allows users to analyze signals that occur only during specific time intervals. Gated Sweep is particularly useful for applications such as pulsed RF signal analysis, including radar and communication systems where signals are present only during certain periods. By using this option, users can synchronize the spectrum analyzer's sweep with external events or triggers, providing enhanced measurement accuracy and insight into time-varying signals. This option is an add-on to the main MS27201A instrument and requires the base unit for operation.
