8663A Specifications
The 8663A signal generator is related to the 8662A in both concept and
structure. Like the 8662A, the 8663A is an extremely low phase noise sig-
nal source, incorporating signal generator modulation capabilities and
output characteristics. The 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 uses and extends the
proven circuitry of the 8662A. Thus, the 8662A and 8663A share many of
the same specifications.

In the remote mode it is possible to have microprocessor clock-related spurious signals
spaced 3 MHz apart at an absolute level of typically less than –145 dBm.

At a 50 Hz line frequency, power-line or microphonically-related spurious signals
may be up to 3 dB higher and appear at offsets as high as 1 kHz from the carrier.

Due to automatic leveling loop bandwidth changes, brief (30 ms) level inaccuracies
may occur when switching through 150 kHz and 1 MHz RF output frequencies.
