35 Obsolete and Discontinued Commands

:TRIGger:THReshold

(see page 1138)

Command Syntax

:TRIGger:THReshold <channel group>, <threshold type> [, <value>]

<channel group> ::= {POD1 | POD2}

<threshold type> ::= {CMOS | ECL | TTL | USERdef}

<value>::= voltage for USERdef (floating-point number) [Volt type]

[Volt type] ::= {V | mV | uV}

The :TRIGger:THReshold command sets the threshold (trigger level) for a

pod of 8 digital channels (either digital channels 0 through 7 or 8 through

15). The threshold can be set to a predefined value or to a user-defined

value. For the predefined value, the voltage parameter is not required.

Query Syntax

:TRIGger:THReshold? <channel group>

The :TRIGger:THReshold? query returns the voltage and threshold text for

analog channel 1 or 2, or POD1 or POD2.

Return Format

<threshold type> ::= {CMOS | ECL | TTL | USER}

CMOS ::= 2.5V

TTL ::= 1.5V

ECL ::= -1.3V

USERdef ::= range from -8.0V to +8.0V.

<value> ::= voltage for USERdef (a floating-point number in NR1.

NOTE

This command is only available on the MSO models.

NOTE

The :TRIGger:THReshold command is an obsolete command provided for compatibility to

previous oscilloscopes. Use the :POD<n>:THReshold command (see page 527),

:DIGital<d>:THReshold command (see page 295), or :TRIGger[:EDGE]:LEVel command (see

page 903).
