# Anritsu MS27101A 9 kHz to 6 GHz Remote Spectrum Monitor (Pre-Owned) # Anritsu MS27101A 9 kHz to 6 GHz Remote Spectrum Monitor (Pre-Owned) ## Key Features At A Glance - 9 kHz to 6 GHz frequency range (tunable to 0 Hz) with 20 MHz IF bandwidth - Sweep rates up to 24 GHz/s for fast signal discovery - Dynamic range >106 dB normalized to 1 Hz bandwidth - SSB phase noise of –98 dBc/Hz at 10 kHz offset at 1 GHz - Integrated web server for view, control, and measurement via Chrome or Firefox - Integrated GPS receiver; frequency accuracy <±50 ppb in GPS High Accuracy Mode - Gigabit Ethernet and USB interfaces with remote control via SCPI commands - Optional Vision and SpectraVision software for automated and specialized measurements The Anritsu MS27101A is a remote spectrum monitor for high-performance, real-time monitoring of the radio spectrum from 9 kHz to 6 GHz (tunable to 0 Hz). It is a single-port RF-IN instrument designed to remain stable over time under continuous operation, delivering superior sweep speeds, high dynamic range, and low spurious levels for fast and accurate measurements. USB and Ethernet interfaces are provided for remote connectivity. Anritsu lists the MS27101A for monitoring interference, white space analysis, unlicensed transmission discovery, and signal coverage. Its IQ block mode and streaming with time stamping support time difference of arrival (TDOA) applications, while the integrated GPS receiver supports monitoring-location and time-synchronization applications. The monitor's measurement set includes occupied bandwidth and channel power, with spectrogram and signal-strength interference analysis. ValueTronics stocks and holds its own inventory in a 20,000 square-foot secure warehouse at 1675 Cambridge Drive, Elgin, Illinois. Every used instrument we sell is inspected and functionally verified by our in-house team before shipment, while new units ship factory-sealed exactly as received — we never open or test a new unit. That combination lets buyers source the MS27101A with confidence in both condition and availability. ## Accessories Supplied - AC-DC Adapter (Part Number 40-187-R) ## Product Core & Specifications Specification Value Frequency Frequency Range 9 kHz to 6 GHz (tunable to 0 Hz) Tuning Resolution 1 Hz Frequency Reference Accuracy ±1.5 ppm (25 °C ± 25 °C) ±1.0 ppm/year aging;
