2.27 Invert Command
Description Sets or gets polarity of current channel.
Command Syntax <channel>:INVerT <parameter> <channel>={C1, C2} <parameter>={ON, OFF}
Query Format <channel>:INVerT?
<channel>={C1, C2}
Query Response <channel>:INVerT <parameter>
Example <channel>:INVerT <parameter>
Set C1 ON:
C1:INVT ON
Read the polarity of channel one.
C1:INVT? Return:
C1:INVT ON
2.28 Coupling Command
Description Sets or gets channel coupling parameters. You can only set coupling value when trace switch off.
Command Syntax COUP (COUPling)<parameter>
<parameter>={a parameter from the table below}
Value Parameters Description
TRACE <trace> Trace switch
STATE <state> State of channel coupling.
BSCH <bsch> Value of base channel.
FDEV <frq_dev> Value of f frequency deviation.
PDEV <pha_dev> Value of position phase deviation.
FCOUP <fcoup>
Value of frequency coupling switch
FRAT <frat> Value of frequency coupling ratio
PCOUP <pcoup> Value of phase coupling switch
PRAT <prat> Value of phase coupling ratio
ACOUP <acoup> Value of amplitude coupling switch
ARAT <arat> Value of amplitude coupling ratio
ADEV <adev> Value of amplitude coupling deviation
where: <trace>={ON, OFF}
< state >={ON, OFF}
< bsch >={CH1, CH2}
< frq_dev >={Default unit is “Hz”, value range depends on the model}
< pha_dev >={Default unit is “
