Key Features
13.6 GHz / 20 GHz Microwave Coverage
Choose 13.6 GHz or 20 GHz coverage for microwave receiver testing, RF module verification, LO substitution, filter response checks and high-frequency component characterisation.
0.001 Hz Frequency Resolution
Fine frequency setting resolution supports narrowband receiver sensitivity tests, swept-frequency characterisation and repeatable stimulus generation for automated RF validation.
Low Phase Noise Carrier
Typical phase noise is specified at −120 dBc/Hz at 1 GHz and 20 kHz offset, supporting receiver, mixer, synthesizer and microwave front-end measurements where spectral purity matters.
AM / FM / PM and Pulse Modulation
Standard analog modulation modes support communication receiver checks, modulation response testing and RF training experiments without requiring a separate modulation source.
Pulse Train and Double Pulse Options
Optional pulse functions support pulsed RF stimulus, radar-style gated carrier testing and timing-response checks for RF chains and microwave subsystems.
Remote Control and Power Meter Correction
USB Host, USB Device and LAN interfaces support SCPI automation, browser control and production test integration. Power meter control can be used to compensate cable and path losses.

Applications
Microwave Receiver Sensitivity
Generate clean RF carriers for sensitivity, blocking, gain compression and dynamic range measurements on microwave receiver chains.
Amplifier and Filter Characterisation
Use swept or stepped CW stimulus for RF amplifier, attenuator, mixer, filter and frequency-converter validation up to 20 GHz.
Automated RF Module Test
SCPI control over LAN or USB enables repeatable production test sequences for RF front-end modules, radios and microwave assemblies.
Microwave and Communication Labs
AM, FM, PM and pulse modulation make the generator suitable for RF communication training and microwave measurement benches.
Pulsed RF Stimulus
Optional pulse functions support gated carrier generation and pulse-response checks for radar-style RF subsystems.
Path-loss Compensation
Power meter control helps compensate cable and fixture losses so the RF level at the DUT is closer to the intended test condition.
