Hi, I'm trying to dump some data remotely, through a GPIB cable, from a HP3577A network analyzer and I'm getting a constant offset (13.01dBm) when pulling the data in log scale (that is, comparing the values in the HP3577A screen with the ones I get on my computer, they are off by 13.01dBm). If I dump the data using a linear scale everything works fine.
Has anybody ever faced a problem like this or have any suggests/comments on why this is happening?

Thanks in advance!

 

I figured it out. It's because using it remotely, the preset condition without the test set has an offset of 13.01dBm!

Thanks
