Remote spectrum monitors for up to 43,5 GHz

24 November 2021 Test & Measurement

The new MS27201A Remote Spectrum Monitor series from Anritsu includes the self-proclaimed 'industry’s first' such instrument that covers 43,5 GHz to support new satellite downlink bands. Combining high RF performance with supporting PC software delivers a compelling package for long-term monitoring in a variety of commercial and regulatory environments.

The MS27201A series includes 9 GHz and 20 GHz remote spectrum monitors, in addition to the 43,5 GHz model. A wide 110 MHz measurement bandwidth to support common satellite downlink spans complements the 43,5 GHz model. With a displayed average noise level (DANL) of -164 dBm and a third-order intercept point (TOI) of typically +20 dBm, the remote spectrum monitors assure accurate signal detection and measurement integrity.

A standard PC GUI with the familiar Anritsu spectrum analyser interface allows users to control multiple instruments and view current spectrum from a single location. As an alternative, Anritsu can have the remote spectrum monitors interface with the MX280001A Vision software. Common trace capture and data storage applications are included in Vision software, eliminating the need for users to develop custom software.

Anritsu also supplies an IQ capture feature that allows users to conduct detailed offline post-processing on signals of interest. Optional LTE and 5G demodulation software further expand monitoring capability, as does VSA software that allows modulation quality measurements to be made on narrowband signals in accordance with industry standards.

The MS27201A series ensures reliable, 24/7 continuous spectrum monitoring over a wide geographic area. A built-in watchdog timer resets the instrument in the event of a software interruption. Should a power disruption occur, the instrument will resume immediate operation with no user intervention required.

The new instruments are standard 19-inch-rack wide and 2U tall, so they can slot directly into test system racks using minimal space. The instruments are powered from a supplied 15 W power block that minimises rack temperature gain.

The MS27201A series is targeted at the increasingly demanding requirements of spectrum owners and spectrum regulators. The remote spectrum monitors deliver stable performance in a variety of applications, including spectrum clearing, shared spectrum monitoring, satellite ground station monitoring, critical site security, interference monitoring and regulatory enforcement.
