Attribute Summary:

Description:

FREQ:CENT and FREQ:SPAN work together to define the band of frequency you want to analyze.

When you change the value of FREQ:CENT, the value of FREQ:SPAN remains constant.

Step size (FREQ:STEP) determines the change in frequency which results when you send UP or DOWN

with this command.

In swept sine instrument mode (INST:SEL SINE; Option 1D2):

The allowable values are 15.625 mHz to 511199.984375 Hz in 2 channel instrument mode and

31.25 mHz to 25599.984375 Hz in 4 channel instrument mode. A value specified by this command

is rounded to the next lower 15.625 mHz step.
