Remote command:
Full Span
Sets the span to the full frequency range of the R&S
FSV/A specified in the data sheet.
This setting is useful for overview measurements.
Remote command:
Zero Span
Sets the span to 0 Hz (zero span). The x-axis becomes the time axis with the grid lines
corresponding to 1/10 of the current sweep time ("SWT").
Remote command:
FREQ:SPAN 0Hz
, see
Last Span
Sets the span to the previous value. With this function you can switch between an
overview measurement and a detailed measurement quickly.
