:TRIGger:PATTern

(see page 1138)

Command Syntax

:TRIGger:PATTern <pattern>

<pattern> ::= <string>[,<edge_source>,<edge>]

<string> ::= "nn...n" where n ::= {0 |1|X|R|F}when

<base> = ASCii

<string> ::= "0xnn...n" where n ::= {0,..,9 | A,..,F |X|$}when

<base> = HEX

<edge_source> ::= {CHANnel<n> | NONE} for DSO models

<edge_source> ::= {CHANnel<n> | DIGital<d>

| NONE} for MSO models

<n> ::= 1 to (# of analog channels) in NR1 format

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

<edge> ::= {POSitive | NEGative}

The :TRIGger:PATTern command specifies the channel values to be used in

the pattern trigger.

In the <string> parameter, each bit corresponds to a channel as described

in the following table:

The format of the <string> parameter depends on the

:TRIGger:PATTern:FORMat command setting:

• When the format is ASCii, the string looks just like the string you see

on the oscilloscope's front panel, made up of 0, 1, X (don't care), R

(rising edge), and F (falling edge) characters.

• When the format is HEX, the string begins with "0x" and contains hex

digit characters or X (don't care for all four bits in the nibble).

With the hex format string, you can use the <edge_source> and <edge>

parameters to specify an edge on one of the channels.

Oscilloscope Models Value and Mask Bit Assignments

4 analog + 16 digital channels (mixed-signal) Bits 0 through 15 - digital channels 0 through

15. Bits 16 through 19 - analog channels 4

through 1.

2 analog + 16 digital channels (mixed-signal) Bits 0 through 15 - digital channels 0 through

15. Bits 16 and 17 - analog channels 2 and 1.

4 analog channels only Bits 0 through 3 - analog channels 4 through 1.

2 analog channels only Bits 0 and 1 - analog channels 2 and 1.
