FREQuency:CENTer {<frequency>|MINimum|MAXimum}
FREQuency:CENTer? [MINimum|MAXimum]
Set the center frequency (used in conjunction with the frequency span). Select
from 1 mHz to 10 MHz (limited to 100 kHz for a ramp waveform). The default is
550 Hz. MIN = 1 mHz. MAX = based on the frequency span and maximum
frequency for the selected function as shown below. The :CENT? query returns the
center frequency in hertz.
– The following equation shows the relationship between the center frequency
FREQuency:SPAN {<frequency>|MINimum|MAXimum}
FREQuency:SPAN? [MINimum|MAXimum]
Set the frequency span (used in conjunction with the center frequency). Select
from 0 Hz to 10 MHz (limited to 100 kHz for a ramp waveform). The default is
900 Hz. MIN = 0 Hz. MAX = based on the center frequency and maximum
frequency for the selected function. The :SPAN? query returns the span in hertz
(can be a positive or negative value).
– To sweep up in frequency, set a positive frequency span.
– The following equation shows the relationship between the span and the start /

Frequency Span (max) = 2 × (Max. Frequency – Center Frequency)
To sweep down in frequency, set a negative frequency span.
