Tortoise

Multi-Band Transmitter

 

tortoise

Tortoise™ is a portable, rugged, high-power transmitter system comprised of dual, independent 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 circuitry 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. Optional LTE, UMTS, CDMA or WiMAX Modulators allow Tortoise™ to simulate base station transmissions or DAS (Distributed Antenna Systems) complete with adjustable step sizes, channel bandwidth and user settable ID Cell, Segment and frame lengths.

Frequently Asked Questions

What type of modulation does Tortoise support?

Tortoise supports optional, internal (factory installed) modulation for IS-95 CDMA, WiMAX OFDMA, 4G LTE and UMTS. Single and dual band modulation are supported but wideband frequencies are NOT under these modulation schemes.
What is the maximum power output from Tortoise?
 
Tortoise class A amplifiers support up to 25 Watts of output power depending upon frequency and modulation schemes. With any optional modulator installed, the maximum power output is 10 Watts.
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?
 
Yes. In addtion, two modulated frequencies may also be transmitted simultaneously for independent data streams all from one transmitter housing.
