Specificatii
Frecventmetru de pana la 2,4GHz pe 8 digiti !
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.

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 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.
4. Frequency reference
Using 5032 package 13.000MHz Warming
voltage controlled crystal oscillator (VC-TCXO), frequency
stability of ± 2.5 ppm.
5. Operating voltage
DC Input: DC 9V ~ 15V (with reverse
polarity protection)
