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
