GAOTek Digital RF Millivoltmeter and Frequency Counter
This compact Digital RF Millivoltmeter and frequency counter measures sinusoidal signal voltage, over a wide frequency range of 10 kHz to 2000 MHz.
Description
GAOTek Digital RF Millivoltmeter and Frequency Counter is a new type of micro-controller digital intelligent instruments. It can measure the sinusoidal signal voltage from 9 kHz ~ 3000 MHz . The instrument uses a QVGA color LCD display with clear reading and has long life. The machine has a good frequency response, small standing wave co-efficient, high sensitivity, low power consumption, small size and is light weight. With RS-232 interface and optional GPIB interface and USB interface, can be remote measurement control. But also and computer and other equipment composed of automated test system, is the workshop production and the laboratory UHF voltage measurement of the necessary equipment.
