I use the N1022A probe adaptor with an 1134A active, diff probe for RF sniffing, generally hooked to a spectrm analyzer.
If I hook the 1134A directly to an Infinium scope, it's working properly.
If I measure gain through the N1022A (it is 50 Ohm Zin and Zout) it has 0 dB gain, again seems to be working properly. The +/- 3VDC and +/- 12VDC are present on its probe power connections per page 16 of:
http://cp.literature.agilent.com/litweb/pdf/N1022-90001.pdf
However when the N1022A is used with the 1134A, the voltage gain from probe tip to N1022A outut is -22 dB. The bandwidth is flat. Is there some communication between these two that is not happening; i.e. the probe identification. Maybe something is broke.
Any ideas?
