:DIGital<d>:THReshold

(see page 860)

Command Syntax

:DIGital<d>:THReshold <value>

<d> ::= 0 to (# digital channels - 1) in NR1 format

<value> ::= {CMOS | ECL | TTL | <user defined value>[<suffix>]}

<user defined value> ::= -8.00 to +8.00 in NR3 format

<suffix> ::= {V | mV | uV}

• TTL = 1.4V

• CMOS = 2.5V

• ECL = - 1.3V

The :DIGital<d>:THReshold command sets the logic threshold value for all

channels in the same pod as the specified channel. The threshold is used

for triggering purposes and for displaying the digital data as high (above

the threshold) or low (below the threshold).

Query Syntax

:DIGital<d>:THReshold?

The :DIGital<d>:THReshold? query returns the threshold value for the

specified channel.

Return Format

<value> ::= threshold value in NR3 format
