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