Modify Function Commands

Note: Most of the modify function parameters may be selected at any time that the unit is in analog mode.
To observe the changes effecting the output, be sure that the appropriate modifying type is selected and
the modify function is on. Some of the parameters cannot be modified for all settings. These are indicated
below. When this occurs, a "Not Appl" (not applicable) message will be displayed on the screen and
syntax error will occur.
If these commands are sent when the unit is in digital mode a "Not Appl" (not applicable) message will be
displayed on the screen and syntax error will occur. The command OUTD0 (analog output) should be sent
at the beginning of any program that uses the analog output.
*TRG
MENA (?) i
MTYP (?) i
TSRC (?) i
DS360 Ultra Low Distortion Function Generator
The *TRG command triggers a burst or a single sweep.The trigger source must
be set to SINGLE.
The MENA command enables the modify function for i=1 and disables it if i=0.
The MENA? query returns the current modify function status.
The MTYP command sets the modify function type to i as described in the table
below. The MTYP? query returns the current type.
i Modify Function
0 LIN SWEEP
1 LOG SWEEP
2 BURST
3 BW NOISE
If the modify function is changed to a type which is incompatable with the
currently selected output waveform, a range error will be sent and the command
will be ignored.
If the parameter currently being displayed is undefined for the new MTYP (for
example: start freq and burst), the "Not Appl" message will appear, a range error
will be returned and the display will be changed to FREQ, regardless of what was
displayed previously.
The TSRC command sets the trigger source for bursts and sweeps to i as
described in the table below. The TSRC? query returns the current trigger source.
