:TRIGger:M1553:POLarity
Syntax
:TRIGger:M1553:POLarity <polarity>
:TRIGger:M1553:POLarity?
Description
Sets or queries the polarity of M1553 trigger.
Parameter
Name
Type
Range
Default
<polarity>
Discrete
{POSitive|NEGative}
POSitive
Return
Format
The query returns POS or NEG.
Example
:TRIGger:M1553:POLarity POSitive /*Sets the polarity of M1553 trigger
to POSitive.*/
:TRIGger:M1553:POLarity? /*The query returns POS.*/
:TRIGger:M1553:ALEVel
Syntax
:TRIGger:M1553:ALEVel <level>
:TRIGger:M1553:ALEVel?
Description
Sets or queries the upper limit of the trigger level of M1553 trigger. The unit is the same
as that of the current amplitude.
Parameter
Name
Type
Range
Default
<level>
Real
Lower limit to
(5 × VerticalScale - OFFSet)
0 V
Remarks
For VerticalScale, refer to the :CHANnel<n>:SCALe command; for OFFSet, refer to
the :CHANnel<n>:OFFSet command.
Return
Format
The query returns the upper limit of the trigger level in scientific notation.
Example
:TRIGger:M1553:ALEVel 0.16 /*Sets the upper limit of the trigger level to 160 mV.*/
:TRIGger:M1553:ALEVel? /*The query returns 1.600000E-1.*/
:TRIGger:M1553:BLEVel
Syntax
:TRIGger:M1553:BLEVel <level>
:TRIGger:M1553:BLEVel?
Description
Sets or queries the lower limit of the trigger level of M1553 trigger. The unit is the same as
that of the current amplitude.
Parameter
Name
Type
Range
Default
<level>
Real
(-5 × VerticalScale - OFFSet) to
upper limit
0 V
Remarks
For VerticalScale, refer to the :CHANnel<n>:SCALe command; for OFFSet, refer to
the :CHANnel<n>:OFFSet command.
Return
Format
The query returns the lower limit of the trigger level in scientific notation.
Example
:TRIGger:M1553:BLEVel 0.05 /*Sets the lower limit of the trigger level to 50 mV.*/
:TRIGger:M1553:BLEVel? /*The query returns 5.000000E-2.*/
