:TRIGger:PATTern

Command Syntax
:TRIGger:PATTern <pattern>
<pattern> ::= <string>[,<edge_source>,<edge>]
<string> ::= "nn...n" where n ::= {0 | 1 | X | R | F} when
<string> ::= "0xnn...n" where n ::= {0,..,9 | A,..,F | X | $} when
<edge_source> ::= {CHANnel<n> | NONE} for DSO models
<edge_source> ::= {CHANnel<n> | DIGital<d>
<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:
Oscilloscope Models
4 analog + 16 digital channels (mixed-signal)
2 analog + 16 digital channels (mixed-signal)
4 analog channels only
2 analog channels only
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
• When the format is HEX, the string begins with "0x" and contains hex

(see page 1208)
<base> = ASCii
<base> = HEX
| NONE} for MSO models
on the oscilloscope's front panel, made up of 0, 1, X (don't care), R
(rising edge), and F (falling edge) characters.
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.
