The Marconi IFR Aeroflex 6960B is a single-channel RF power meter delivering precise power measurements across 30 kHz to 46 GHz with dynamic range from −70 dBm to +44 dBm. The instrument combines manual front-panel operation via numeric keyboard with full GPIB automation for ATE integration. Auto-zero circuitry with digital storage across five ranges holds carry-over errors to ±0.03% and zero accuracy to ±1% of full-scale deflection. Measurement accuracy reaches ±0.5% in linear mode and ±0.02 dB in logarithmic mode, with traceability to National Standards at ±0.7%.

– Typical Applications
Manufacturing test, field service, power amplifier characterization, transmitter validation, and multi-frequency RF source measurement across microwave and millimetre-wave bands.
– Compatibility & Integration
GPIB Option 001 provides remote programmability of all front-panel functions except test modes. Rear-panel analog outputs interface with external instrumentation and process control systems. Sensor linearity correction accommodates non-ideal response profiles for enhanced measurement confidence.
