ITEM NAME:Green PLJ-8LED-R RF Signal Frequency Counter Cymometer Tester 0.1~1000MHz Description: - 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. Specification: - 1. Gate time: - 0.01 S - 0.10 S - 1.0 S - 2. Measurement channels (channels are low impedance): - low channel - Measuring range: 0.1 MHz ~ 60 MHz - Accuracy: Â ± 100Hz (0.01 1s gate time) - Â ± 10Hz (0.1 seconds gate) - Â ± 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: Â ± 6400Hz (0.01 seconds gate) - Â ± 640Hz (0.1 1s gate time) - Â ± 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 .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. Frequency reference. - RF IN (signal input): HX2.54-2P socket.
