AS2273 ultra-high frequency digital LCD millivolt meterDetailed product description：

AS2273 ultra-high frequency digital LCD millivolt meter (2GHz) adopts large-scale integrated circuits and microprocessor chips, with automatic measurement and data processing functions, user-friendly interface, LCD display screen, displaying instrument status and measurement results simultaneously, high-precision reading with five significant digits, automatic range/manual range setting, and measurement results displayed on the same screen as effective value and dBm value
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
Automatic zeroing function: Accurately measure small signals and achieve automatic zeroing of the instrument
Equipped with RF power indicator (power meter function)

AS2273 ultra-high frequency digital LCD millivolt meter/power meter (2GHz) with coaxial detector (more accurate measurement for frequencies above 1GHz)
