[time-nuts] HP 106a oscillator connectors question

Thanks for all the info. They are the 1/4-32 (S-93 compatible) Microdot !!! I ordered a double ended cable and will cut it in half to give me the two connections I need (5Mhz out and EFC in). Cheers, Corby ___ time-nuts mailing list --

Re: [time-nuts] HP 106a oscillator connectors question

Several have suggested that these are 10-32 connectors. If this is true, a 10-32 nut will thread on them with no trouble. I believe these **may** be the 1/4" diameter variant that was 93 ohm characteristic impedance. I **think* they are called an S-93. Still 32 tpi, but 1/4" in diameter. You

Those appear to be "Microdot 10-32" S-50 connectors to me. See: https://en.wikipedia.org/wiki/Microdot_connector http://www.cdint.com/catalog/model/BM-174-6 http://www.mouser.com/pdfdocs/TEConnectivity_Nanonics_MicrodotCatalog.pdf --- see page 94

They look like microdot connectors. Like what I have on my ultrasound transducers. On Jun 3, 2016 3:59 PM, wrote: > Well the checkout of the 106A oscillator section is going well. > > I ran it for 6 hours and the outer oven came down OK, will have to wait > until I can do a

There is a connector that looks like an SMA connector, but isn't. Unfortunately I don't remember what they are called. I have seen them used on microwave equipment (like VNA's). Some idiots will really try hard to mate them with SMA's, but just damage the connectors... and you don't want

Well the checkout of the 106A oscillator section is going well. I ran it for 6 hours and the outer oven came down OK, will have to wait until I can do a longer attended run for the inner oven as it takes 8 1/2 hours per the manual to come down! This unit was not built with the fine adjust via an
