[time-nuts] STEL boxes

I am going through my lab finally sorting things out. I have uncovered two STEL boxes I bought a while back. They are models 5430 and 5440. The 5430 is a baseband coder and the 5440 is a coder/data demodulator. Because of the labels (e.g. P(Y) clock, C/A clock, etc), I believe these to be GPS

Hi Mark: Probably. STEL made GPS receiver chips, like used in the Quantic 5200 GPS timing reciever, see: http://www.pacificsites.com/~brooke/Q5200.shtml and in order to test their chips they built test equipment, see: http://www.pacificsites.com/~brooke/5001a/5001A.html Have Fun, Brooke
