Anritsu MS2024A Handheld VNA Master, 2 MHz to 4 GHz

The Anritsu MS2024A is a handheld vector network analyzer delivering accurate S-parameter measurements across 2 MHz to 4 GHz. Engineered for field engineers and technicians, this portable instrument performs vector-corrected 1-port and 2-port measurements, Distance-To-Fault diagnostics, and return loss characterization without sacrificing the performance of benchtop systems.

– Technical Specifications

Frequency coverage spans 2 MHz to 4 GHz with 1 Hz resolution and 2.5 ppm accuracy. Measurement speed reaches 2 ms or 850 µs per data point, supporting up to 4001 arbitrary data points. The corrected directivity exceeds 42 dB across the full frequency range. Transmission dynamic range delivers 100 dB, enabling measurements in RF-rich environments with immunity rejection to +17 dBm.

IF bandwidth adjusts from 10 Hz to 100 kHz. Test port power settings include High (0 dBm) and Low (−35 dBm) for 2-port transmission measurements. Vector correction follows open-short-load calibration with interpolation capability and minimal drift error.
