Ladder Attenuator Installed - Its Very Quiet But..

I added a sample relay switch ladder attenuator into the vacuum chamber. It is very quiet but there appears to be a small leak. The leak may be caused by re-using the Viton seals a second time or possibly a leak in my vacuum test set-up. The leak is very tiny but I still need to track it down.

One step forward, two steps back…
