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.

Roy
