| MODULATION SCHEMES : |
|
|
CW |
Unmodulated CW signal. Note, GSM data modulation cannot be turned on from
the main Gator screen. |
|
External |
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. |
|
GSM RND |
Gator outputs GSM modulation with internally-generated and random PN (pseudo-random)
data. |
|
GSM BUFF |
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. |
Cellular, WiMAX, LTE, LMR, Paging, SMR, GSM, ISM, WCS, iDEN, AMPS, PACS, ETMS, ETACS, IS-136, AWS and more
