Anritsu MS46122A – Vector Network Analyzer; 2 Port, ShockLine

The Anritsu MS46122A is a 2-port Vector Network Analyzer from the ShockLine series, engineered for cost-effective RF and microwave component characterization. This PC-controlled instrument leverages VNA-on-chip technology to deliver reduced cost and enhanced accuracy across manufacturing, research, and development workflows. It measures all four S-parameters (S11, S21, S22, S12) plus user-defined combinations of incident and reflected wave amplitudes, with optional time-domain capability.

Technical Specifications Three frequency variants address different measurement requirements: 1 MHz to 8 GHz, 1 MHz to 20 GHz, and 1 MHz to 43.5 GHz (specifications above 40 GHz are typical). Dynamic range reaches 100 dB with a maximum measurement level of 115 dBm. Measurement speed is 220 µs per point, supporting up to 16,001 points per graph. Source power is selectable at -3 dBm or -20 dBm, with maximum output at -3 dBm. Receiver linearity extends to +5 dBm compression point at 40 GHz. Directivity achieves 42 dB with manual calibration and 50 dB with the AutoCal module. Port match exceeds 8 dB across the frequency range. The internal 10 MHz crystal oscillator reference signal provides the basis for all specifications.
