Hi all,
I picked up this 5A21N Differential Amplifier plugin for my Tek 5441, but have a strange problem with it.
With the inputs grounded there are these pulses present on the trace.
Visual inspection doesn't show any obvious problems, and the plugin does work as it should if I feed in a differential signal to the + and - inputs. The attenuator has an effect on the amplitude of the pulses, so it must be coming from before it.
Here is the service manual, and attached is a photo of my problem.
Any help is much appreciated!
