The Anritsu MS2038C VNA Master is a dual-function handheld instrument combining Vector Network Analyzer and Spectrum Analyzer capabilities in a single platform. Operating from 5 kHz to 20 GHz, it delivers S-parameter measurements, cable and antenna characterization, and signal analysis for field installation, commissioning, and maintenance of RF and microwave systems. The 2-port VNA configuration with 2-path architecture achieves 100 dB dynamic range and 350 µs measurement speed per data point, supported by 12-term error correction. The integrated spectrum analyzer extends coverage to 9 kHz with sensitivity reaching –161 dBm (1 Hz with preamplifier) and modulation analysis capability. Field operability is ensured through 3-hour autonomous battery runtime, an 8.4-inch display, and 4.8 kg total weight.
