Description
The triangular wave output of a function generator is used to
modulate a 500 MHz signal which is applied to the spectrum analyzer
SIGNAL INPUT. The signal is demodulated in the zero span mode to
display the triangular waveform. Sweep time accuracy for sweep
times
ms is tested by checking the spacing of the signal peaks on
the displayed waveform.
