:COUPling:PHASe:MODE
Syntax :COUPling:PHASe:MODE {OFFSet|RATio}
:COUPling:PHASe:MODE?
Description Set the phase coupling mode to phase deviation (OFFSet) or phase ratio (RATio).
Query the selected phase coupling mode.
Parameter Name Type Range Default
{OFFSet|RATio} Discrete OFFSet|RATio RATio
Explanation  Phase deviation mode: the phase of CH1 and CH2 have certain deviation relation.
The parameter relations are P
CH2
=P
CH1
+P
Dev
(the reference source is CH1);
P
CH1
=P
CH2
-P
Dev
(the reference source is CH2). Wherein, P
CH1
is the phase of CH1,
P
CH2
is the phase of CH2 and P
Dev
is the phase deviation.
 Phase ratio mode: the phase of CH1 and CH2 have certain ratio relation. The
parameter relations are P
CH2
=P
CH1
*P
Ratio
(the reference source is CH1);
P
CH1
=P
CH2
/P
Ratio
(the reference source is CH2). Wherein, P
CH1
is the phase of CH1,
P
CH2
is the phase of CH2 and P
Ratio
is the phase ratio.
 If the phase of CH1 or CH2 exceeds the phase upper limit or lower limit of the
channel after the channel coupling, the instrument will automatically adjust the
phase upper limit or lower limit of the other channel to avoid parameter
overrange.
 Select the desired phase coupling mode and set the corresponding phase
deviation ( :COUPling:PHASe:DEViation ) or phase ratio ( :COUPling:PHASe:RATio )
before enabling the phase coupling function ( :COUPling:PHASe[:STATe] ). You
cannot set the phase coupling mode and phase deviation/ratio after the phase
coupling function is enabled.
Return Format The query returns OFFSET or RATIO.
Example :COUP:PHAS:MODE OFFS /*Set the phase coupling mode to phase deviation*/
:COUP:PHAS:MODE? /*Query the phase coupling mode and the query
returns OFFSET*/
