Stop Freq
Sets the frequency at the right side of the graticule.
When
Stop Freq reaches the lower frequency limit, the start frequency is set to the lowest
available frequency and the stop frequency is changed to be more than the start frequency
by the minimum span (1
kHz). Center Freq will be updated to the start frequency plus
one-half of the span, or to the start frequency plus 500 Hz, and
Res BW will be set to 10 Hz.
CF Step
Enables you to set the step size for the center frequency and start/stop frequency functions.
Once a step size has been selected and the center frequency function is active, the step
keys change center frequency by the step-size value. In addition, the step keys change the
start and stop frequencies twice the value of the CF Step setting. The step size function is
useful for finding harmonics and sidebands beyond the current frequency span of the
analyzer.
