[:SOURce[<n>]]:PHASe:INITiate
Syntax
[:SOURce[<n>]]:PHASe:INITiate
Description
Performs the "align phase" operation.

[<n>]
Discrete
{1|2}
When omitted, by default, the operations are
carried out on GI.
Remarks
When you perform the "align phase" operation, the instrument will re-configure the
two channels to output according to the preset frequency and phase.
For two signals whose frequencies are the same or in multiple relationship, this
operation can align their phases. Assume that 1 kHz, 5 Vpp, 0° sine waveforms are
output on GI, and 1 kHz, 5Vpp, 180° sine waveforms are output on GII. Use the
oscilloscope to acquire the waveforms of the two channels and stably display the
waveforms. It can be found that the phase deviation between the two waveforms is no
longer 180°. At this time, perform the "align phase" operations and then the
waveforms has a phase deviation of 180°. You do not need to adjust the start phase of
the function/arbitrary waveform generator manually.
[:SOURce[<n>]]:FUNCtion[:SHAPe]
Syntax
[:SOURce[<n>]]:FUNCtion[:SHAPe] <wave>
[:SOURce[<n>]]:FUNCtion[:SHAPe]?
Description
If modulation is not enabled for the specified function/arbitrary waveform generator
channel, this command is used to select or query the output signal waveform. If
modulation is enabled for the specified function/arbitrary waveform generator
channel, this command is used to select or query the modulated carrier waveform. At
this time, if you select PULSe, NOISe, or DC, the modulation function is automatically
disabled.

Remarks
The MSO5000 series provides 7 kinds of built-in waveforms, including Sinc, ExpRise,
ExpFall, ECG, Gauss, Lorentz, and Haversine.
Return
Format
The query returns SIN, SQU, RAMP, PULS, NOIS, DC, SINC, EXPR, EXPF, ECG, GAUS,
LOR, HAV, or ARB.
Example
:FUNCtion SQUare /*Sets the waveforms output from GI to SQUare.*/
:FUNCtion? /*The query returns SQU.*/
