The Marconi IFR Aeroflex 1600S is a 1 GHz radio communication test set designed for testing and servicing radio equipment across multiple standards and protocols. This dual-function instrument operates as both receiver and RF signal generator, or in full duplex mode with selectable frequency offsets. It integrates spectrum analysis, oscilloscope, power metering, SINAD measurement, and protocol compliance testing into a single platform suitable for benchtop and field deployment.
