The HP / Symmetricom 58536A has a gain spec of 0 +-3 db so something is clearly wrong.
Agreed. I didn't have the spare energy to follow up on that.
Did you power it through a spare port?
Yes. Port 4. Will look at that again.
Also, the isolation spec is 26 db @ L1. The 50 db spec is for L1 +- 40 MHz. I looked inside mine and found that there's an input filter(-1db), 21 db amp, 4 way resistive splitter(-12db), output filter(-4db), and 4 db pad. That matches your measurement of 28 db isolation - no power is required for that.
Indeed. But I want propper gain and group delay measures too. It was a fun lab to do just to get started.
