vrf Memory leak ??

Question asked by VRFuser on Nov 19, 2002
hello.

i am encountering what appears to be
capacitively coupled 60 HZ noise in this
measurement with a 3458A DMM.

until we properly address this in hardware modifications,
suggestions for an interim digital filter method
would be helpful.

the peak of interest is at around 80m, and i would
like to filter out the other stuff (which appears to be
around 60 HZ in nature) ....

*******************************

Use a notch filter in VEE. Easiest way is an analog filter.

See the analog filter design example- all you need is to create the
correct transfer function for whatever filter you like

I've attached below a snippet that creates a bandstop transfer function.

Take your data, turn into "waveform" , run through this filter

regards

Stan
