TRIGger:A:UPPerthreshold:RF
Arguments
<NR3> is a floating point number that specifies the threshold to use, in the
currently selected RF units (using RF:UNIts). The range is (ref level – 40 dBm) to
(ref level + 10 dBm), but never less than –65 dBm or more than +30 dBm.
Examples
TRIGger:A:LOWerthreshold:RF —1.000E+1 sets the threshold to –10 dBm.
TRIGger:A:LOWerthreshold:RF? might return -30.0000, indicating that the
threshold set to –30.000 dBm (assuming the units are currently set to dBm).
TRIGger:A:MODe

NORMal waits for a valid trigger event.
Examples
TRIGGER:A:MODE NORMAL specifies that a valid trigger event must occur before
atriggerisgenerated.
TRIGGER:A:MODE ? might return :T RIGGER:A:MODE NORMAL indicating that a
valid trigger event must occur before a trigger is generated.
