Re: 8594E input attenuator issue?
Hi, Remember that an attenuator must be terminated in 50 ohms to have the correct attenuation. You could do a simple test with your DMM, with the attenuator assembled (except for the cover over the

Re: 8594E input attenuator issue?
Quickly cranking out some numbers, the 20 dB section appears to be working. 20Log(60/6.4) = 19.44.dB. Allowing for a bit of inaccuracy due to using a DSO, that looks OK. 20Log(60/1.6) = 31.38 dB,
