FREQuency:CENTer {<

>| 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.
Center Frequency (max) = Max. Frequency –
• The following equation shows the relationship between the center
frequency and the start /stop frequency.
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).
Frequency Span (max) = 2 X (Max. Frequency – Center Frequency)
• To sweep
up
in frequency, set a positive frequency span.
To sweep
down
in frequency, set a negative frequency span.
• The following equation shows the relationship between the span and
the start /stop frequency.
Frequency Span = Stop Frequency – Start Frequency
