Noise on the output of 2651A

Post by tommyhsieh » March 11th, 2018, 11:40 pm

Hi

I used a Keysight oscilloscope DSO-X 2004A to monitor the output of 2651A and I found it is noisy no matter I use 2-wire or 4-wire configuration.
The screenshots as below. Can anyone tell me it's normal or not?

Noise level when generating pulsed current, 5-Ohm resistor is connected (600mA, 2-wire, 100mA bias)

Thanks and Regards,
