1. A 65MHz frequency meter and frequency counter tester measurement based on for Microchip's PIC16F648A for signal frequency counter
2. The frequency reference uses a temperature compensated voltage controlled crystal oscillator (±2.5 ppm VC-TCXO); signal frequency counter cymometer tester module adopt unique gate control method and precise time algorithm (non-interruption mode)
3. The gate (display refresh) time is 0.1 second, and the frequency value is displayed in real time; Frequency measurement and cymometer tester module accessories accuracy 10Hz/100Hz (shift one bit to the right) is optional for frequency meter
4. Digital signal frequency counter and frequency meter for generator is Double IF design, IF value and addition/subtraction mode can be preset separately without affecting each other; The display driver adopts LED display special chip, the digital tube has high brightness and less external interference
5. LED display signal frequency counter and generator cymometer tester adopts six-digit 0.56-inch digital tube display, invalid automatic blanking, and eight levels of brightness adjustable

First, I think that the product description may indicate that these PLJ6LED units cover the frequency range up to 1 GHz as do the similar-looking 8-digit PLJ8LED units. This is incorrect. On these units the upper frequency is 60 MHz. In any case I've had no problems with these 6-digit counters. As close to accurate as I can test, quite sensitive and are adjustable over 8 levels of brightness. No problems!
