AS2272(1GHZ) Ultra High Frequency Digital Liquid Crystal Millivolt MeterDetailed product description：

AS2272 ultra-high frequency digital LCD millivolt meter (1GHz) adopts large-scale integrated circuits and microprocessor chips, with automatic measurement, data processing functions, and user-friendly interface
Adopting an LCD display screen, it simultaneously displays the instrument status and measurement results, with high-precision readings of five significant digits
Automatic range/manual range setting, measurement results displayed on the same screen as valid values and dBm values
Advanced dual diode detection and low-noise deep negative feedback amplification circuit ensure measurement stability

Δ dB key: arbitrarily set the reference 0V and 0dBm, quickly measure gain, amplitude frequency characteristics, insertion loss, frequency response, transmission coefficient, etc

AS2272 ultra-high frequency digital LCD millivolt meter (1GHz) with automatic zero calibration function: accurate measurement of small signals, can achieve automatic zero adjustment of the instrument
