Here’s a selection of electronic instruments manufactured by Nagard a UK based company in the sixties. The Nagard 300 series oscilloscopes boasted a 40MHz bandwidth and compared well with the US Tektronix 500 series. Data sheets cover the 301 wide band scope and the model 321 which supported plug-in dual channel Y deflection amplifiers for the dual beam 5 inch CRT.

Nagard 5002C Pulse Generator
The 5000 series pulse generators were widely used in laboratories providing a stable source of signals. These valve designs could achieve 10nS rise times and provide multiple pulse trains.

The Pulse generator 5002c-s is a very interested instrument. I have been using this instrument
for many years now on vintage radars and H2S. Today it is not working and I wish
to have it on my work bench. The problem is that I do not have the schematic diagram.
If some one could help me to obtain a copy of the schematic, I would be very grateful and ready
to pay some fee for the circuit diagram.
It is very stable and very accurate pulse generator.

Had a quick look but could not find a schematic for the 5002c. If it turns up I’ll be glad to scan and put a copy here.
