Title: Schaffner/Tesek: Missing manual for the PNW 2050.8
Post by: AndersJ on February 25, 2016, 03:11:27 pm

Does anyone have a pdf copy of the manual for the Schaffner/Tesek: PNW2050.8

Hi Anders,

If you contact Teseq directly they should be able to help.  Let me know if they don't.

I contacted Teseq UK a few hours ago, and they sent me the manual immediately.
Excellent service!

With the manual I figured out why the user interface behaved as it did.
Some options depend on which PNW is used.
I did not understand that.

My current issue now is to figure out why the open circuit output voltage
is half of what is chosen on the user interface.

With a load of 2.4K it drops to about half again,
and the pulse length shortens, from a previously OK waveform.

I get the feeling there might be something wrong with the output stage,
like a high output impedance, or a bad capacitor bank switch.
A high power device like this should be able to drive most anything and still maintain its output.

Or am I making a simple/stupid mistake here?
