Specification &lo% for sweep times 5100 seconds

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 ~20 ms is tested by checking the spacing of the signal peaks on the displayed waveform.
