[:SOURce<hw>]:FREQuency:SPAN <Span>

Determines the extent of the frequency sweep range. This setting in combination with the center frequency setting ([:SOURce<hw>]:FREQuency:CENTer) defines the sweep range.

This parameter is related to the start and stop frequencies. If you change the frequency, the span changes accordingly.

fSPAN = fSTOP - fSTARt

fSTARt > fSTOP is permitted.

Parameters:
<Span>
float
Range: full frequency range
Increment: see the data sheet: RF characteristics > Resolution of setting
*RST:400E6
Example: FREQ:CENT 400 MHz

sets the center frequency of the frequency sweep to 400 MHz.

FREQ:SPAN 200 MHz

sets a span of 200 MHz. This sets the sweep range to 300 MHz to 500 MHz.

Manual operation: See "Span - Frequency Sweep"
