Hi all
Title says it all. Serial number B096537. Anyone have any clue as to what Mod GD actually is? Craig

No – definitely GD. Ie not a 0 with a bit missing – a very clear and unambiguous G.

Hi Craig,

I may have the companion plugin! I have a 7B80 Mod GB, serial number B042313. Looking at the front panel of my 7B80 it appears to be normal except for the TIME/DIV range. The only sweep speeds it has go from 10uSec/Div (slowest) to 5nSec/Div. So it can't sweep slower than 10uSec/Div compared to an ordinary 7B80 which can go as slow as 5Sec/Div. Also, the regular 7B80's fastest speed is 10nSec/Div so the GB version has one faster sweep speed. Dennis

I hope not. I live in an area where earthquakes are rare but I
believe a 4-5 quake can cause objects to fall and perhaps minor
damage, depending on its location and depth. Here (South West
Australia) a minor quake usually just sounds like a heavy truck
rumbling by.

I'd much rather live in an active earthquake zone than some place that's infested with tornadoes. But then again, maybe I'm just used to them. I've often though about the type of house I'd build if I had to move to Kansas or similar. Something to keep the scopes from going to Oz (as in the land of...) -Dave

Would someone like to change the subject line? Earthquakes are important stuff – but nothing whatever to do with the subject line!

You could have. :)
I am pretty sure I have read about modified timebases which were limited to the faster sweep speeds for special applications (photography? storage? area 51?) but I went through my collection of Tektronix catalogs and did not find anything. I have an early 7B85 timebase which uses a different faceplate with the horizontal sweep markings rotated 3 steps counterclockwise but I do not see how that could be related.

Comparing to a vanilla 7B85 there seems to be two additional multiway

connector positions on the main board, although they align with nothing on the overlying trigger board. Whether these are linked with a ribbon, or mate with a different trigger board? Apart from that the functionality is identical. So unless someone like Hakan knows something, it will have to remain a mystery. Craig

Well I hate to resurrect an old thread but I was looking through one of my manuals for the 7B85 and there is a hand written note that says "MOD GD Opt 10 Turn Potentiometer on Time/Div Cal Replaces 311-1590-00" but no other information that I can find on MOD GD. In trying to find more information about the note I found this post about MOD GD. Thought that info might be helpful to someone. ~Lesley
