Description

The Agilent 8664A signal generator is suited for basic receiver testing up to 3.0 GHz. With Option 004 (low-noise enhancement), it can be used for out-of-channel receiver testing or as a clock source where having the lowest phase jitter is important. Radar testing can be done by adding Option 008 (pulse modulation) .

Pulse width and delay can be internally adjusted between 50 ns and 999 ns, eliminating the need for an external pulse generator. Standard FM rates of up to 2 MHz and deviations to 10 MHz are suitable for many applications such as high-speed digital communications.

Key Points

<-140 dBc/Hz typical SSB phase noise at 20 kHz offset at 1 GHz with Option 004

<-100 dBc nonharmonic spurious to 2 GHz reduces error when testing spurious immunity of receivers

AM, FM, and optional pulse modulation

0.01 Hz frequency resolution

Onsite repair and calibration
