The Anritsu MS2725C is a high-performance handheld spectrum analyzer delivering precision RF and microwave measurements across 9 kHz to 7.5 GHz. With a displayed average noise level of -155 dBm typical (1 GHz, preamplifier ON) and dynamic range exceeding 70 dB, it excels at signal monitoring, interference analysis, and component testing in both laboratory and field deployments. The instrument combines fast acquisition with flexible bandwidth control—resolution bandwidth spans 1 Hz to 10 MHz, while video bandwidth reaches 0.1 Hz to 10 MHz. Phase noise performance of -110 dBc/Hz at 10 kHz offset (1 GHz carrier) ensures accurate characterization of complex signals. An integrated tracking generator (100 kHz to 7.5 GHz, -20 to 0 dBm output) supports VSWR, return loss, and insertion loss measurements. Optional modulation analysis capabilities enable AM, FM, and digital demodulation (ASK, FSK, PSK, QAM), with measurements including modulation depth, frequency deviation, symbol rate, and error vector magnitude. Real-time spectrum analysis features channel power, adjacent channel power ratio, and occupied bandwidth assessment.
