The Marconi IFR Aeroflex 2966A is a 1 GHz radio communications test set integrating signal generation, spectrum analysis, power measurement, and modulation analysis into a single instrument. Designed for cellular, trunked radio, and GSM applications, it operates across 100 kHz to 1 GHz and supports analog cellular standards (TACS, AMPS, NMT), MPT 1327 trunking, and comprehensive GSM testing. The unit functions equally well in benchtop and field environments, delivering precision across multiple test domains without requiring separate instruments.
Technical Specifications
RF signal generation spans 100 kHz to 1 GHz with 400 mW maximum output. Output levels vary by connector type and modulation scheme: N-Type sockets deliver -135 dBm to -45 dBm (GMSK) and -40 dBm (FM/PM/AM) in single-port modes, extending to -135 dBm to -35 dBm (GMSK) and -10 dBm (FM/PM) in two-port configurations. TNC sockets provide -135 dBm to -25 dBm (GMSK) for single-port operation and -135 dBm to +10 dBm (FM/PM) for dual-port modes. The N-Type socket sustains 50 W continuous power with 150 W overload protection.
Modulation analysis supports AM, FM, PM, Pulse, FSK, ASK, and PSK across modulation frequencies of 20 Hz to 15 kHz (carriers to 36 MHz) and 20 Hz to 20 kHz (carriers to 400 MHz). Modulation accuracy reaches ±0.5% for 250 Hz to 5 kHz frequencies and ±1% for 50 Hz to 20 kHz. Six independent tone sources—three modulation generators and three audio generators—operate from 1 Hz to 20 kHz, combinable to 100 kHz.
Spectrum analysis covers 100 kHz to 1 GHz with max hold for TDMA/GSM signals and alignment capabilities for IQ modulators and IF/LO inspection. The integrated power meter measures 1 mW to 150 W at ±7% accuracy.
