The Anritsu MS2667C is a portable spectrum analyzer covering 9 kHz to 30 GHz, designed for microwave and millimeter measurement applications. The instrument is positioned as a compact, lightweight platform that combines synthesized local oscillator stability, automatic calibration, and a 5.5-inch color TFT-LCD display in a 15 kg chassis. The standard configuration includes RS-232C and GPIB interfaces, a memory card interface supporting PCMCIA Rel. 2.0 cards up to 2 MB, and an external mixer input/output that extends frequency coverage into the millimeter range when paired with the MA2740A through MA2746A external mixers.
The MS2667C is intended for evaluation of radio equipment and microwave/millimeter signal characterization. Built-in measure functions handle frequency counting with 1 Hz resolution, C/N, channel power, adjacent channel power, occupied frequency bandwidth, burst average power measurement, and template pass/fail comparison in both time and frequency domains. The FM-demodulated waveform display function supports measurement of frequency deviation and frequency switching times for radio equipment and VCOs. With the external mixer ports, the instrument addresses applications above 30 GHz including measurements in the K, A, Q, U, V, E, and W bands up to 110 GHz.
Anritsu Corporation is a Japanese precision-measurement company headquartered in Atsugi, Kanagawa, with roots extending to 1895. In 1993, Anritsu acquired Wiltron Company, the U.S.-based RF and microwave instrument manufacturer, consolidating Wiltron's network analyzer and microwave product lines under the Anritsu brand. Today Anritsu operates as a single corporate brand for its full T&M portfolio, with no subsequent major restructuring or rebrand of the spectrum analyzer product line.
