This unit

The Advantest TR4131 is a spectrum analyzer operating from 10 kHz to 3.5 GHz, delivering precise frequency, amplitude, and phase measurements across RF and microwave applications. This instrument combines wide dynamic range exceeding 100 dB with resolution bandwidth from 1 Hz to 3 MHz, enabling detailed signal characterization in telecommunications, EMC, and component testing environments. Advanced measurement capabilities include modulation analysis, occupied bandwidth measurement, quasi-peak detection conforming to CISPR standards, and field-strength measurement with antenna calibration compensation.
