SOURce<Ch>:POWer<Pt>:ALC:LPNoise <Boolean>
Defines whether Low Phase Noise Mode shall be activated whenever ALC is used on a port in channel
<Ch> (Activate Low Phase Noise Mode for ALC in ALC Config dialog).
<Ch>
Channel number
<Pt>
Port number. This suffix is ignored; the setting applies to all ports.
<Boolean>
Enables (ON) or disables (OFF) automatic activation of Low Phase Noise
Mode.

Types
Device-specific, command or query
Example:
See SOURce<Ch>:POWer<Pt>:ALC:AUBW
SOURce<Ch>:POWer<Pt>:ALC:PIParameter AUTO | MANual
Enables automatic or manual setting of the PI controller parameters at source port <Pt> in channel
<Ch> (Control Loop Parameters > Coefficients in ALC Config dialog).
<Ch>
Channel number
<Pt>
Port number
Parameters
AUTO – Automatic setting, depending on the bandwidth
(SOURce<Ch>:POWer<Pt>:ALC:BANDwidth). With automatic bandwidth selection
(SOURce<Ch>:POWer<Pt>:ALC:AUBW <Boolean> ON) this is the only option.
MANual – Manual setting using
SOURce<Ch>:POWer<Pt>:ALC:PIParameter:GAIN and
SOURce<Ch>:POWer<Pt>:ALC:PIParameter:ITIMe.

Types
Device-specific, command or query.
Example:
SOURce1:POWer:ALC:AUBW OFF; BANDwidth 10000
Disable automatic bandwidth setting and select a 10 kHz loop bandwidth.
SOURce1:POWer1:ALC:PIP MAN; :SOURce1:POWer1:ALC:PIP:GAIN 0.35; ITIM 6E-7
Enable manual entry of PI controller parameters and define the proportional gain and
the integration time.
SOURce<Ch>:POWer<Pt>:ALC:PIParameter:GAIN <prop_gain>
Defines the proportional gain of the PI controller at source port <Pt> in channel <Ch> (Control Loop
Parameters > Kr in ALC Config dialog). This setting takes effect when manual setting of the controller
parameters is enabled (SOURce<Ch>:POWer<Pt>:ALC:PIParameter MANual).
