Residual SSB Phase Noise (dBc/Hz):
Signal Generators
Spectral purity is the key contribution of both the HP 8662A and 8663A,
making them ideal for many radar, satellite communication, and phase
noise measurement applications. Typical absolute phase noise performance of these generators at a 1 kHz offset is as low as –135 dBc/Hz,
depending on the band of operation.
The frequency range of the HP 8662A is 10 kHz to 1280 MHz. It
offers versatile AM/FM, using either inter nal 400 Hz and 1 kHz rates or
externally applied modulating signals which can be either ac- or dc-coupled. It also has simultaneous modulation capability.
The HP 8663A and 8662A provide the U.S. Air Force MATE (Modular Automatic Test Equipment) capability, via Option 700. This option is
an external translator that allows the signal generator to be controlled by
the MATE language CIIL (Control Interface Intermediate Language).

HP 8663A Specifications
The HP 8663A signal generator is related to the HP 8662A in both concept
and structure. Like the HP 8662A, the HP 8663A is an extremely low phase
noise signal source, incorporating signal generator modulation capabilities and output characteristics. The HP 8663A also offers increased frequency range to 2560 MHz, increased output level to +16 dBm, and the
addition of phase and pulse modulation while maintaining high spectral
purity. The result is a highly flexible and powerful signal generator that
3
uses and extends the proven circuitry of the HP 8662A. Thus, the HP 8662A
and HP 8663A share many of the same specifications.

HP 11721A Frequency Doubler
The HP 11721A doubler is an ideal accessory for extending the usable
frequency range of signal generators, frequency synthesizers, or other
signal sources. Operating on input frequencies of 50 MHz to 1300 MHz,
it provides a doubled output in the range of 100 MHz to 2600 MHz. The
HP 11721A will work well with any RF source with an output in the range
of 50 to 1300 MHz.
