The HP 8643A signal generator has been optimized to provide the
performance required for out-of-channel receiver tests while maintaining
a low price. Many performance capabilities have been included as
standard, such as pulse modulation. Reliability is enhanced by an
electronic attenuator on the 1 GHz version. Instead of mechanical
relays, the HP 8643A uses solid state components accurate to within 1.0
dB for setting levels. An advanced internal modulation synthesizer
provides coverage to 400 kHz and two-tone capability with the selection
of sine, square, triangle, sawtooth, and white Gaussian noise waveforms.
