I have three of these units, and have been looking for the right
manual for years. Thanks for this part, but I believe the SPTB is
different from the FRK in the schematics and some of the construction
detail - for example, since it's 5 MHz vs 10, that circuit is
different, not just the crystal
Is the Tektronix p/n on the unit ? it may be 119--xx

Hello,
Can anybody shed some light on this particular model:
Model - SPTB-100/LN-001
Efratom part No. 703-200-11
Date Code 8609
(I have looked at K04BB's website, it has lots of other models, but not this
one).
Thank You,

I have an SPTB-100. It seems to be a custom version of a standard
FRK(LN) rubidium for Tektronics.
I got mine around 2000. (Mine is an 88 date-code vs. your ancient 86
version.) It didn't work initially because the internal Xtal oscillator
wouldn't sweep through lock frequency. Changed a cap
