Subject: [TSCM-L] For Sale: Micro-Tel VDA-60 Raster Analysis "van Eck" System

OK, this is a unit that only ex-government types will likely recognize.

This is for TWO Microtel VDA-60's, which allow you to take an 
oscilloscope and turn it into a raster analysis system where you can 
tweak the horizontal and vertical sync, plus set up all kind of 
gating to trigger an image. The user sets this unit up, then adjusts 
the settings and any repetitive signal such as video can be 
"rasterized" on the scope screen. Yes, you actually can use this to 
watch TV on an oscilloscope, and yes, you can use it to see the 
emission leaking off computer screen, and yes, some folks get all 
excited and think this is some kind of van Eck or TEMPEST receiver, 
but in reality it is a very valuable piece of TSCM gear and is pretty 
much worthless for eavesdropping.

The VDA-60 also contains a TDR pulse generator, which when coupled 
with an ordinary oscilloscope will give you a great little time 
domain reflectometer that you can use to trace wiring. A system 
includes a small Tek 335 35 MHz hand-held oscilloscope, which on it's 
own is worth quite a bit. The system goes into a heavy black 
leatherette briefcase, similar to the old style telco repair kits 
popular in the early 80's, and includes various fuses, cords, cables, 
etc, plus the original swivel style headphones, and the ** DC ** 
power cord for the scope as well as the normal AC cord.

The full kit would also include an audio amp, probes, and couplers, 
and a few other minor items but they are not being offered in this 
sale. This VDA kit also includes an AC power cord, but also takes 
regular 9 volt batteries, plus an extra VDA-60 (so you get a total of 
two VDAs and one scope).

I will not include a manual for the VDA with the sale, but will 
include the Oscilloscope users manual. Condition on all equipment is 
good, with normal wear and tear, but you may need to calibrate the 
system or make a minor repair due to the age , but they currently 
work fine. The briefcase (actually more of a small suitcase) has done 
a lot of traveling, and has "some character and patina", but all 
three latches and the hinges work fine, the foam is all in excellent 
shape but the outside of the case is a little scuffed up.

Note that this includes *** TWO OPERATIONAL VDA-60's ***, plus an 
original *** 35 MHz Oscilloscope *** and this would made an nice 
addition to a museum as a holy relic from the very end of the Cold 
War, or you can tweak it up for use during sweeps.

I will except reasonable offers, but will not export this unit.

As usual, I accept all major credit cards, cash, checks, money 
orders, camels, cows, goats, sheep, gold coins, daughters beyond the 
age of consent, etc, etc, etc..
