The PG509 manual is not exactly the same as the High Amplitude Pulse
Generator. There were minor modifications and additions made over time, but
it will be more than close enough that the Theory of Operation section will
apply quite nicely and most of the schematic should be the same. Some parts
might have changed, but only in minor ways. Parts may have been moved around
to different places.

pulsed line generator??
Thanks Dennis and Rob for yours valuable help, second the PG509 manual just
downloaded..no tunnel or step recovery diode, just a robust avalanche
bipolar transistor which is easy replaceable part if coming burn I hope not
the case!!..
Thanks again friends!!

Look through the archives for more info like this post. The link to
the manual is in this post:

Subject: RE: [TekScopes] Manual or schematic available for the High
Amplitude PulseGenerator?
Which One? There are three:
. The 1st one Tek made has no Tek part number on it but it does
say
on the front panel: High Amplitude Pulse Generator. This unit has a
Step Attenuator, Variable Amplitude control, and a GR874 plug which
you connect a length of coax to. The coax acts as a charged line and
determines the duration of the output pulse.
. The 2nd one Tek made is in the new color scheme and says PG509
Pulse Generator across the top ribbon. It eliminated the Step
Attenuator, Variable Amplitude, and charge line in favor of a fixed
width fixed amplitude pulse which was then fed into an AT5010
Programmable Attenuator to adjust the amplitude. The manual is available
from www.ko4bb.com.
. The 3rd one Tek made says 067-1094-99 Pulse Generator across the
top ribbon. It is identical, as far as I can tell, to the second one.
I believe they are all essentially the same inside except that the
first one had a Step Attenuator, a Variable Amplitude, and the GR874
plug for the charge line.

Here the link to this almost new pulsed generator, at first glance is
a transmission line pulser with 300ps ..but no model or number at all.
I just brought it with the hope work right...but a good service manual
will be very appreciated and gratefully.
