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.
- CW module combos include frequencies for CDMA, Cellular, PCS, Paging, ETACS, iDEN, SMR, ISM, LMR, UMTS, GSM, LTE, WiMAX, Wi-Fi, AWS & more
- Optional LTE, UMTS, CDMA IS-95 or WiMAX Modulators for base station simulation (10 Watts output maximum)
- Two independent transmitter module bays
- Power amplifier with continuous adjustable power output ± 0.1 dB over 32 dB range
