Unmodulated CW signal. Note, GSM data modulation cannot be turned on from the main Gator screen.
Transmitter will modulate with user-supplied and filtered I and Q data from an external source. This is via BNC connectors located on the top panel of the Gator.
Gator outputs GSM modulation with internally-generated and random PN (pseudo-random) data.
GSM modulation with user-downloadable BCCH (base station control channel) stored data, downloaded by the user with PC loader software. This is via the RS-232C jack in rear. User must supply the base station data to be output, gator will repeat this transmission indefinitely.
