The number of the project: the parameters of the unit, the unit, the unit, and the unit
1. Measure the low-frequency range: 1Hz ～ 50MHz
2 Measure the low-frequency voltage range +/- 0.7V ～ 15V
3 Measuring low-frequency resolution 1 Hz
4 Measure the high frequency range 10MHz ～ 2.4GHz
5 Measure high-frequency voltage range +/- 100mV ～ +/- 5V
6. Measurement of high-frequency resolution 1KHZ Hz
7. Working voltage: 7 ～ 12. VDC
8. Working current: <50. MA
9 Working temperature: -40 ℃ ～ 65 ℃
10. Storage temperature: -40 ℃ ～ 65 ℃
11 Dimensions: 57 * 50 * 20 mm length X width X height
Note: The low-frequency signal is not an AC signal, and a capacitor of about 1 OuF is connected in series at the input signal end.
The low-frequency signal is DC-coupled. For AC-coupling, please measure the capacitance in series.
