The Anritsu MS27103A is a remote spectrum monitor built for remote RF signal monitoring across a 9 kHz to 6 GHz frequency range (tunable to 0 Hz). It ships as a standard configuration with 12 RF input ports, with 24 RF input ports available via Option 424. A high-speed switch inside the monitor provides measurement capability for each RF input, and greater than 30 dB of isolation is provided between each RF input port to assure the integrity of the measurement.
The MS27103A is typically used with three- or six-sector BTS architectures, with multiple carriers per sector. Its measurement set covers occupied bandwidth and channel power, and its interference-analysis capabilities include spectrogram and signal strength. IQ block mode and streaming with time stamping support time difference of arrival (TDOA) applications, and the integrated GPS receiver supports monitoring location and time-synchronization applications.
ValueTronics stocks and holds its own inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer. Holding inventory directly in our own facility lets us manage condition, configuration, and fulfillment under one roof.

Important: Maximum continuous input: +22 dBm, ±50 VDC (100 MHz to 6 GHz, ≥10 dB attenuation). For lower frequencies, derate maximum continuous input by 4 dB per decade.
Important: The MS27103A requires a frequency option to be ordered; Option 0706 (9 kHz to 6 GHz Frequency Range) must be selected with the base unit.
Important: Option 110 replaces the screw terminal with a 3-pin AC line receptacle.
Important: A GPS antenna (Part Number 2000-1528-R, SMA(m) with 5 m cable, 3 dBi gain, requires 5 VDC) is an optional accessory and is not included with the standard instrument; it is required for the integrated GPS receiver's location and time-synchronization functions.
Important: Vision software and SpectraVision software are optional; automated spectrum measurements, alarms, geo-location, TETRA/Satellite measurements, and channel scanning require the corresponding software options.
