The Anritsu MS2661C is a portable spectrum analyzer engineered for RF signal analysis from 9 kHz to 3 GHz. It delivers stable, drift-free measurements across general-purpose RF testing, EMI characterization, CATV maintenance, cellular communications, and digital broadcasting applications. Weighing 11 kg in standard configuration, the instrument combines laboratory-grade performance with field portability. Its bright full-color display remains legible in direct sunlight, while synthesized frequency generation ensures minimal drift during extended measurements.
Technical Specifications
Frequency coverage spans 9 kHz to 3 GHz with 1 Hz resolution via integrated frequency counter. Resolution bandwidth ranges from 1 kHz to 3 MHz standard, expandable to 30 Hz, 100 Hz, and 300 Hz with Option 02. Video bandwidth covers 1 Hz to 3 MHz with manual or automatic selection. Amplitude measurements range from DANL to +30 dBm, delivering over 80 dB dynamic range on a single screen. Phase noise performance reaches below –100 dBc/Hz at 10 kHz offset. Second harmonic distortion measures –75 dBc; two-signal third-order intermodulation distortion reaches –80 dBc. Frequency span accuracy is ±2.5% for spans ≥10 kHz and ±5% for narrower spans with Option 02. Noise level stabilizes within 30 minutes of power-on.
