Specification
Brand : Yuecoom
BulletPoint1 : RF Frequency Meter: With Microchip's PIC16F648A, 2.4 GHz frequency meter. Using temperature-compensated voltage controlled crystal oscillator (2.5 ppm VC-TCXO)
BulletPoint2 : Frequency Counter: PLJ-8LED is a 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
BulletPoint3 : Reasonable Design: 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
BulletPoint4 : Features: This frequency meter has 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
BulletPoint5 : Simple Operation: Circuit is simple and reasonable structure, two-button control. Using eight 0.56 inches high brightness digital display, eight adjustable brightness. The settings are automatically saved, boot directly call

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: ± 100Hz (0.01 1s gate time)
± 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 signally frequency high or low channel channel, identifying the frequency of 60 MHz. Such as when the input signally amplitude is greater than 60 MHz shortage can not automatically select high channel, the channel should manually select high frequency measurement.
