Gator Class A Stimulus Transmitter

Each Gator™ Transmitter is housed in a high impact ABS water-resistant case. It has a built-in agile frequency synthesizer, dynamically controlled power amplifier and a built-in modem and DTMF (touch-tone) decoding allowing remote control of all transmitter parameters via a phone line or cellular telephone. Remote adjustments include the power level, channel or frequency assignment, and transmit On/Off. All Gators™ feature a Class A amplifier for the purest and most stable signal output.

Why won't my Gator turn on when I hook it up to a gas portable generator?

Certain model generators output an impure noise spike in the AC output. This anomaly has been traced to ignition noise riding on top of the sine waveform. So while this output is fine for most devices requiring AC power, the Gator will not turn on because it requires pure regulated AC power. Several model Honda generators have been tested and approved for this application, and also this problem can be easily remedied by simply using an inexpensive AC surge suppressor found in any convenience or hardware store.

Does Gator transmit a complete CDMA signal?

No, not really. The Crocodile is Berkeley's premium CDMA stimulus transmitter. It has been designed to fit in between existing base stations using any available PN offset, without effecting normal operation of the other base stations. It outputs Pilot I & Q signals used for measuring correlated signal strength and includes all timing and clocking circuits to meet IS-97A requirements, including clock holdover in excess of 24 hours in the absence of GPS signals.

How do I control the Gator once it is up on the crane?

All of the Gator's necessary functions may be controlled via any touch-tone telephone line, a cellular phone or from any PC that has Gator Controller software installed. Every Gator is equipped with an internal RS-232C and Bell 202 modems to control all functions from any PC with supplied software.
