@McBrice , do you have a DC block in there ? (don't ask why I ask!!!!!)
No, these let through DC, however, my SA is a DSA815-TG which can supposedly take up to 50VDC on the inputs, (well above what I will be working with), so it shouldn't be an issue. However, I may build myself a DC block for future use.
Regarding "ruining the SA ports due to mechanical inaccuracy", they will be mounted via a not-so-cheap SMA to N-Type adapter, so they don't have a direct connection to the SA.
McBryce.
That would have saved me a LOT of swearing.
I use the 'savers' on my 3.5 gear.
Yokogawa TA520 Time Interval Analyzer
Sunding bicycle computer for $9, shipping in, from China. No doubt a P.O.S. but let's see how long it lasts. First thing I'll do once coin cells die is wire up an external AAA supply so I can use rechargeables.

You are going to want to keep DC off those attenuators.

Interesting unit. Do you also have a 53310A on hand, for comparison?

The attenuators claim "DC to 3GHz up to 2W" on the label.
McBryce.
Pulling the DC down in your circuit under test is a bad idea.

maybe a silly question but, how does that achieve a 25ps resolution with only 43msps??
@willb does that have a 'tuning eye' display tube? Looks in pretty good condition.
It sure does! The photo is from the eBay auction, the seller said it was in working condition, I should have it this Friday!
This may be an 'electronics only' section, not sure - but after a long specification process. My custom 10 string guitar build has started!
It will be similar to this one, except green (and other technical small details that's probably not of interest):
The tuning will be ADGBEADGBE, from 27.5Hz to 1661Hz (28th fret on high E string) without any pinch harmonics or trickery! Extended range? Yes
The neck is 31×27.5? fanned frets to help get the appropriate tension across the range.

A brand new fully loaded X11 "hot air station"
Go on! Just for the fun of it, try removing a BGA chip with that!
McBryce.
I suspect there will be enough heat to remove just about anything. Even on multilayer with big groundplanes
Don't think the boards themselves will survive though.
@willb , I still have a 12yo boy feeing about how cool they are !!!!!
@Fortran does it have the oxygen lance aka gas axe? now that is serious fun! (bloody messy though and watch the oxygen disappear)
No only the welding and cutting tips.
I'm getting the gauger though because I need to remove some poor welds that's been covered up by poorer welds on the digger.
It looks like a seriously fun tool.

Do you play that instrument like a guitar or like a chapman stick?
Logic Pro 8, to replace my old Logic 8 that got stolen
Along with some 3.3/5V FTDIs as I had everything in the same bag so didn't have any more of those either, and a couple of ESP8266 modules to
play with stay up to date.
