[:SOURce[<n>]]:PHASe:INITiate
[:SOURce[<n>]]:PHASe:INITiate
Execute align phase operation.
Parameter
[<n>] Discrete {1|2} If omitted, operating on source 1 by default
Explanation Executing align phase operation, the instrument will re-configure the two channels and
enable the generator to output with specified frequency and start phase.
For two signals whose frequencies are the same or in multiple, this operation will align
their phases. For example, assume a sine waveform (1kHz, 5Vpp, 0°) is outputed from
Source1, while another one (1kHz, 5Vpp, 180°) from Source2. Use another oscilloscope to
sample and display the two signals, you will see that the waveforms shown on the
oscilloscope do not always have a phase deviation of 180°. At this point, execute align
phase operation and the waveforms shown on the oscilloscope will have a phase deviation
of 180° without any adjustment of the start phase of the generator.

[:SOURce[<n>]]:FUNCtion[:SHAPe]
Syntax [:SOURce[<n>]]:FUNCtion[:SHAPe] <wave>
[:SOURce[<n>]]:FUNCtion[:SHAPe]?
Description When modulation of the specified source channel is not enabled, these commands are
used to select or query the output waveform. When the modulation is enabled, they are
used to select or query the carrier waveform. At this point, if PULSe, NOISe or DC is
selected, the modulation will turn off automatically.
Parameter
[<n>] Discrete {1|2}
If omitted, operating on
<wave> Discrete
{SINusoid|SQUare|RAMP|PULSe
|NOISe|DC|INTErnal|EXTernal}
SINusoid
Explanation INTErnal: Built-in waveforms (7 built-in waveforms are provided by DS1000Z,
including Sinc, Exp.Rise, Exp.Fall, ECG, Gauss, Lorentz and Haversine)
EXTernal: Arbitrary waveform
Return
The query returns SIN, SQU, RAMP, PULS, NOIS, DC, INTE or EXT.
