Re: HP detector
I find it a bit odd for them to specify a voltage rather than power , the only time I have seen this was for detectors that were used with slotted lines because slotted lines used a probe which is not

Re: HP detector
Thank you, Lothar, thank you, n8zmTWH. Particularly the excerpt from the cut sheet; what I was able to find out before was always catalog data (not a specific datasheet), and the Vp-p was not

Re: HP detector
This is cut from an HP doc I found online, maybe the same one you have. Note that it says 3 V RMS, and (4.2 V pk). Other items in that line were rated in mW, so ignore that here. Sent: Saturday,

Re: HP detector
So since this a RF detector I would imply that the 3V RMS is undrerstood to be in a 50ohm system , usually most wideband detectors are “force matched” either by using a internal 50ohm resistor or

Re: HP detector
Back to this topic, as I've finally acquired an HP 8471A and want to make sure I'm not frying it during my first use. The maximum levels allowed are specified at "3Vrms" "peak or average" -

Re: Scoping the Power Rails [8566B]
SMB and its threaded brother SMC was designed as a connector for internal signal routing , if I remember correctly the spec was 4GHz for the 50ohm and 2GHz for the 75ohm variant , in recent years it

As I have done for myself and other, happy to lay out card extenders for other members of this group. I am in BC Canada. If you are in North America I often can send you blank PCB for the cost of

Re: Scoping the Power Rails [8566B]
I've been lucky so far.? I can only test out to 3 GHz for impedance and all look ok.? I only use short ones then transition to real SMA microwave test leads. I would echo what others have said

What did you start with - looks like one of the card baffles from an older PC could be used. Did you shape the entire thing or did you start with something "laying around"

Bruce, I made several actually. This one was handy, it is made from titanium sheet but others are stainless as I first indicated. Once you make one you see it is easy enough so you can then make them
