Tortoise Multi-Band Stimulus Transmitter


Tortoise Multi-Band Stimulus Transmitter


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 complete with adjustable step sizes, channel bandwidth and user settable ID Cell, Segment and frame lengths.
