PLJ-8LED-H RF Signal Frequency Counter Cymometer Tester Module 0.1~1000MHz

PLJ-8LED is a cost-effective frequency display component of 8-bit digital tube display. It is mainly used for the display of frequency values of transceiver and other equipment, and can also be used for conventional frequency measurement. This component has the characteristics of compact and delicate, reliable performance, good visual effect and low cost.

Features:

With Microchip's PIC16F648A, 2.4 GHz frequency meter. Using temperature-compensated voltage controlled crystal oscillator (2.5 ppm VC-TCXO). Unique gate control and precise time algorithm (non-timed interrupt). Gate (display refresh) time 0.01 seconds / 0.1 seconds / 1.0 seconds, real-time display frequency value. Single-ended input design, three-channel frequency measurement (low channel / high channel / Auto Channel). Dual frequency design, value and IF / down mode can be preset separately. Using eight 0.56 inches high brightness digital display, eight adjustable brightness. Circuit is simple and reasonable structure, two-button control, simple operation. The settings are automatically saved, boot directly call.

± 10Hz (0.1 seconds gate)

± 1Hz (1.0 seconds when the gate)

Low channel sensitivity:

0.1 MHz ~ 10 MHz: better than 60mVPP

10 MHz ~ 60 MHz: better than 60mVPP

60 MHz ~ 75 MHz: Not tested

high channel (divided by 64)

Measuring range: 20 MHz ~ 2.4 GHz

Accuracy: ± 6400Hz (0.01 seconds gate)

± 640Hz (0.1 1s gate time)

± 64Hz (1.0 1s gate time)

High channel sensitivity:

20 MHz ~ 30 MHz: better than 100mVPP

30 MHz ~ 60 MHz: better than 50mVPP

60 MHz ~ 2.4GHz: not tested

Auto Channel

Automatically selected according to the input signal frequency high or low channel channel, identifying the frequency of 60 MHz. Such as when the input signal amplitude is greater than 60 MHz shortage can not automatically select high channel, the channel should manually select high frequency measurement.

3,IF settings

Independent double-IF design, adjust the minimum frequency step of 100 Hz,frequency range 0 ~ 99.9999 MHz, can be set to increase or decrease the IF frequency mode.
