[time-nuts] fast edge, rise time.

[Bill Reed]

Hi,

Since you guys are interested in fast pule generators, I have one you may be 
interested in.
I got it in govt. auction about 25 years ago for ~ $ 50.00. I will sell it 
to anyone for  $ 50.00 plus shipping.
I prefer to sell to someone who will restore and use it rather than parting 
it. It has more than $ 50.00 parts in it.
There are a 30 turn 6.5 inch diameter hard line, wide band hybrid coupler, 
diode assembly and several adapters and attenuators.
I believe the hard line discharges into a step diode. The power supply 
includes 200 V plus other voltages.
If I remember correctly ( I have no high speed scope now ) the pulse is 2 
nanoseconds wide with a 280 picosecond rise time and and 2.5 Vpp.
I checked with a 200 MHz digital scope and can see a pulse that verifies my 
scopes bandwidth. The rate generator works but has problems.
See facebook (reedbn at otelco.net) for pictures under Impulse.
