Power Supply: DC 5V 1A

Maximum print resolution: Each line should be ≥ 25 mm (including the portion where the waveform crosses over)

Input impedance: The input impedance should not be greater than 10nA

Polarization resistance voltage: A DC polarization voltage of ±mV is applied; the sensitivity variation range should be ±5%

Minimum detection signal: For 10Hz,20μThe sinusoidal signal induced by VP-P deflection should be detectable.

51K is connected between the input terminal and the neutral electrodeΩ resistor and 0.047μF capacitor in parallel with impedance

Within the frequency range of 4.10 GHz, the noise level at the input should be as follows:

The noise level of the collection box should be ≤15μVP-P

Common Mode抑制度 Collection box: The common mode抑制度 should be ≥100dB

Low-frequency characteristics: The time constant should be no less than 3.2 s
