Hi,
now that my 3577A is working again, I´m looking for an affordable S-Parameter Test Set or an alternative, since the prices + shipping of these sets are higher than what I paid for the VNA
Just a Q regarding the connectors of the subassemblies in the 35677 S-Parameter Test Sets.
It looks as if the connectors to and from the coaxial relay (33311B) and the directional Bridges (3577-66502) are all of the SMA female type.
The ´Port1´ and ´Port2´ outputs of the two bridges are of N-type but it appears to me that rather they feature SMAs with an SMA-to-N adapter screwed on.
Is that true?
I assume one doesn´t need additional D-Blocks when a (original) 35677 is connected to the VNA? Are those only required for useage of the VNA alone?
As alternative DIY-Setup ... would those cheap chinese/ucrainian 0.1-3000MHz bridges be suitable (with their Ref-otputs terminated into 50R)?
regards
Calvin
btw. found prices in the 1990 HP catalog - 3577A: 25,570$, 35677A: 4,100$ - which would be ~52,000$ and ~8,400$ respectively. What a whopper
