2-140 MSO5000-E Programming Guide
 When the modulating waveform amplitude reaches the maximum value, the
frequency of the carrier is increased by "frequency offset". When the modulating
waveform amplitude reaches the minimum value, the frequency of the carrier is
decreased by "frequency offset".
 Only when FM is selected for the specified function/arbitrary waveform generator
channel, can the frequency offset of FM be set.
Return
Format
The query returns the frequency offset in scientific notation.
Example
:MOD:FM 100 /*Sets the frequency offset of FM of GI to 100 Hz.*/
:MOD:FM? /*The query returns 1.000000E+2.*/
[:SOURce[<n>]]:SWEep:TYPE
Syntax
[:SOURce[<n>]]:SWEep:TYPE <type>
[:SOURce[<n>]]:SWEep:TYPE?
Description
Sets or queries the sweep type of the specified signal source channel.

{LINear|LOG|STEP}
LINear
Remarks  LINear: the frequency of the signal changes linearly.
 LOG: the frequency of the signal changes in log form.
 STEP: the frequency of the signal changes with ladder-like step.
Return
Format
The query returns LIN, LOG, or STEP.
Example
:SWEep:TYPE LOG /*Sets the sweep type of GI to LOG.*/
:SWEep:TYPE? /*The query returns LOG.*/
[:SOURce[<n>]]:SWEep:STIMe
Syntax
[:SOURce[<n>]]:SWEep:STIMe <time>
[:SOURce[<n>]]:SWEep:STIMe?
Description
Sets or queries the sweep time of the specified signal source channel.

<time>
Integer
1 ms to 500 s
1 s
Remarks After modifying the sweep time, the function/arbitrary waveform generator will restart to
output from the specified "Start Freq".
Return
Format
The query returns an integer ranging from 1 ms to 500 s.
Example
:SWEep:STIMe 30 /*Sets the sweep time of GI to 30 s.*/
:SWEep:STIMe? /*The query returns 30.*/
