HZ332 1Hz-4.5GHz HF RF Frequency Meter Digital Frequency Counter Measures Pulse & Radio Frequency

HZ332 1Hz-4.5GHz HF RF Frequency Meter Digital Frequency Counter Measures Pulse & Radio Frequency

Description:
HZ332 is a small frequency meter that can measure low-frequency and high-frequency signals. It also adds a 500KHz pulse accumulator.

It is simple to use, and different test methods can be selected through buttons.

Applications:
* To measure pulse frequency
* To measure radio frequency

1. Measuring low frequency: 1Hz～10MHz
2. Measuring low-frequency voltage: ±0.8V to ±7V
3. Measuring low-frequency resolution: 1 Hz
4. Measuring high frequency: 10MHz～4.5GHz
5. Measuring high-frequency voltage: -12dBm to +10dBm
6. Measuring high-frequency resolution: 1KHZ
7. Working voltage: 7～12VDC
8. Working current: < 50mA
9. Working temperature: -40℃ to 65℃
10. Storage temperature: -40℃ to 65℃
11. Size: 57 x 50 x 20 mm/2.2 x 2 x 0.8" (LxWxH)

Package Included:
* 1 x Frequency Meter

Attention:
* The measured low-frequency signal is not an AC signal. Connect a capacitor of about 1OuF in series with the input signal terminal for measurement.
* The measured low-frequency signal is DC-coupled. If AC-coupled is needed, please connect a capacitor in series before measuring.
