A multipurpose RF instrument integrating a VNA (vector network analyzer), spectrum analyzer, field strength meter, and an audio frequency signal source. It can do full single port vector measurements and 2-port scalar network analysis.

These units are mainly used for adjusting various RF circuits, such as filters, amplifiers, splitters, combiners, input/output impedance testing, antenna system feed analysis, and detecting RF signal amplitudes at all levels.

This unit can also perform field strength measurement, which is useful for checking the correct operation of low powered devices with integrated antennas and spectral analysis when searching for interference sources.

This unit has (6) major modes of operation (w/ multiple sub-menus): Reflection test (S11), Transmission test (S21), Spectrum analyzer (SPEC), Field strength meter (FIELD), RF signal source (RF SOURCE) and Audio signal source (AF SOURCE) generators.

• Vector network analysis from 9kHz to 4.1GHz. 1Hz minimum frequency step. 1kHz RBW.
• LCD display: 3 in. x 2 in. (7.6cm x 4.8cm) high-contrast IPS screen with 700 x 440 pixel resolution.
• Battery (18650 x 4) endurance is: 7 hours. Charging time (from depleted) is: 5 hours.
• 7.8 in x 4.5 in. x 1.8 in. (20cm x 11.4cm x 4.6cm) dimensions at 2.65 lbs. (1.2kg), very portable for field operations.
