DESCRIPTION
The TRIG_SELECT command is used to set the
trigger type and the type’s option
HT which is an option of the TRIG_SELECT
command is related to the TRSL command. The
TRSL command could set the
< trig_slope>. The
HT’s polarity will also be changed.
The TRIG_SELECT? query returns the current
trigger type.
COMMAND SYNTAX
TRig_SelEct <trig_type>,SR,<source>,HT,
<hold_type>,HV,<hold_value>
TRig_SelEct<trig_type>,SR,<source>,CHAR,
<characteristicse>,POL,<polarity>,SYNC,<sync_
type>,LINE,
<line>
TRig_SelEct INTV,SR,<source>,VERT,<vertical>
OPTION
<trig_type>: = {EDGE, GLIT,INTV,TV,}
GLIT means pulse trigger, INTV means slope
trigger and TV means video trigger.
Options: SR HT HV POL CHAR SYNC
LINE VERT
HT,<hold_type>:is used to set pulse type.
<hold_type> : = {TI, PS, PL,PE, IS, IL,IE}
TI means holdoff, PS means that the pulse width
is smaller than the set value. PL means that the
pulse width is larger than the set value. PE means
that the pulse width is equal with the set value. If
you want to set the Px(x is S,L,E), the <trig_type>
must be set to GLIT.
IS means that the interval is smaller than the set
value. IL means that the interval is larger than the
set value is interval larger. IE means that the
interval is equal with the set value. If you want to
set the Ix(x is S,L,E),the <trig_type> must be set
to INTV.
HV,<hold_value>:is used to set trigger time
<hold_value> : = See instrument Operator’s
Manual for valid values
