8.6.2.5 PHASE Sub-system
[SOURce :]
PHASe
: ON
: OFF
[SOURce :] PHASe : ON
Description : This command sets the transition angle of the waveform when
it out. Default DEGREE ON is 0 degree.
Query Syntax : [SOURce :] PHASe : ON?
Parameters : <NR2>, valid range: 0.0 ~ 359.9
Return Parameters : <NR2>
[SOURce :] PHASe : OFF
Description : This command sets the transition angle of the waveform when
it quit.
Query Syntax : [SOURce :] PHASe : OFF?
Parameters : <NR2>, valid range: 0.0 ~ 360.0, 360.0 : means IMMED.
Return Parameters : <NR2>
8.6.2.6 TRACE Sub-system
TRACe
: RMS
TRACe
Description : This command sets waveform data of user-defined. It needs
1024 data points to construct a period of waveform. Users have
to normalize the data as the maximum point equal to 32767 or
the minimum point equal to -32767.
Syntax : TRACe <waveform_name>, <amplitude> {,<amplitude>}
Parameters : <waveform_name>:US<n>, n=1~6, <amplitude>:<NR1>, valid
range: -32767 ~ 32767.
Example : TRACe US1 100 200 …32767... 500 800 <= 1024 points
This command needs about 5 sec to execute.
TRACe : RMS
Description : This command sets the rms value of user’s waveform. Users
need to calculate the root mean square value of 1024 data
points.
Syntax : TRACe : RMS <waveform_name>, <rms>
Parameters : <waveform_name>:US<n>, n=1~6, <rms>:<NR1>, valid range:
0 ~ 32767.
Example : TRACe : RMS US1 27000
