Manufacturer: *Control Data Computing devices*
Model: *SDA-103 Sig. Dist. Meter TTY*
Price: $50.00 This is a Control Data, SDA 103 signal distortion meter. It
will measure distortion on RS-232 or 60 / 20 ma dc loops (T-R-S jacks) . It
is particularly good for setting up the signal generator contacts on a 28
or 35 TTY. I have the complete service manual including all schematics. The
input is a BNC and included is an external RS-232 adapter. There are twelve
preset baud rates that can be selected.
It was built in Canada and is in excellent condition. Everything works as
it should.
$50.00 plus shipping or P/U in Waterloo Ont.
