[Test-Equipment] PTS 040

Hi Bob
 
It sound like you might just have the System Section of the manual, that  
usually runs to around 30 pages and is model specific.
It generally contains block diagrams with chassis layouts  and schematics 
for the PSU section.
 
The full manuals include more detailed chapters for the various  internal 
modules, with schematics and parts lists.
The good news is that some at least of those modules tend to be common  to 
different models so downloading the PTS160 manual, for  example, should 
provide additional useful information.
 
Coming back to your query about keying/switching the oscillator  output, I 
was hoping to be able to refer you to an  appropriate interface on the 
remote control section, which should be  detailed in your section of the manual, 
but now see I may have been  over optimistic.
 
There is an option for remote level control, which presumably also  applies 
also to the PTS040, on pin 22 of the BCD remote control interface, and I  
was thinking that grounding this might reduce the output to zero, but  
looking at the schematic for the OA output section in the PTS160 manual suspect  
this would not be the case, and that some experimentation would be  necessary.
 
In practice it would probably be more straightforward just to build an  
interface buffer and key that, which would have the additional advantage  that 
it would also be available for other signals sources if you wanted to  
experiment.
 
regards

I do  have a complete 33 page user manual.
The few schematics are certainly not  at the component level.
With the exception of the power supplies, the  modules are just blank
p/n rectangles showing the interconnecting node  lines.
