WiMAX MultiBand Stimulus Transmitter

 

Tortoise MultiBand Stimulus Transmitter

Tortoise™ is a portable, rugged, high-power transmitter system composed of dual independent, transmitter modules giving the user freedom to transmit on any 2 unique frequency bands simultaneously without the need for expensive and bulky additional transmitters. Tortoise features two dynamically controlled Class A amplifiers for the cleanest signal output and VSWR protection. Tortoise features built-in thermal overheat protection circuity with quad cooling fans to ensure against overheating during operation. Remote adjustments include power level, channel or frequency assignment and transmit On/Off via USB, RS-232 and Ethernet from anywhere. An optional WiMAX modulator allows the Tortoise transmitter to simulate a fully functional 802.16e base station for the ultimate in deployment accuracy and precision.

FAQs


Why won't my Tortoise 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 Tortoise 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.

Can Tortoise transmit from 2 modules at the same time?

No, but you can mix and match 2 completely different frequencies in one unit so that you do not have to leave the field to transmit another signal.
