Greenkeyers,
Here are some details about the Sperry (Canada) Combination Teletest
test set I have:
Made by Sperry Gyroscope Company, Canada
The type number is ST AGC 2PS 1
The left side is the "Distortion Analyzer" and the right side is the
"Telegraph Generator"
It operates at distortion levels from 0 to 45 percent, baud rates from
45.5 up to much high, and bits from 5 to 8, and a good variety of
loop currents.
The generator and analyzer both operate with balanced or unbalanced
outputs.
The thing has a number of low frequency crystals inside and is solid
state. So I'd expect it to be quite accurate (that is if the
trannysistors are not germanium and all retired.)
Any documentation or experience would be greatly appreciated.
