The Anritsu MS27201A RSM is operated from a 15 VDC source connected to the rear panel. This can be achieved with the Anritsu AC-DC adapter, which can be purchased as an optional accessory. Refer to the instrument Technical Data Sheet for more options and accessories.

The Remote Spectrum Monitor automatically turns on when power is applied to the rear panel power input port and takes approximately 60 seconds to completely power-up and to load the instrument software. At the completion of this process, the instrument is ready for use.
