The Delay Trigger Mode - HP 54501A Programming Reference Manual

The Delay
Trigger Mode
In
the Delay Trigger Mode
the
TRIGGER:QUALIFY
command can be
used to select
the EDGE, PATTERN,
or
STATE
mode
as a
qualifier.
When
the
EDGE qualifier
is selected all
Edge
parameters and commands
can be used to set the Source and
Slope.
When
the
PATTERN qualifier
is
selected all Pattern commands can be used to
set
the
pattern mode
parameters. When the
STATE
qualifier
is selected all State commands
can be used to set the state mode parameters.
The
next
settings
(in
front panel order) are the delay
settings. The
DELAY
command
is used to set
the Time or Count parameter and the
amount of delay.
To
set
the delay to
time
use the
command
TRIGGER:DELAY TIME,
<
time
>,
and to
set the
delay to count
use
the command
TRIGGER:DELAY EVENT
<
number_events
>.
If the trigger delay
is
set
to Event (count) you can then
set
the delay
source and slope. To
set
the delay
source use the
command
"TRIGGER:DELAY:SOURCE CHANNEL2"
and to
set
the delay slope
use
the command
"TRIGGER:DELAY:SLOPE POSITIVE".
Next (on the front panel)
is
the "trigger
on"
field.
The
values
within
this
field are
set
with the
OCCURRENCE
command.
To
set
the number of
occurrences use
the command
syntax
"TRIGGER:OCCURRENCE
3333".
To
set
the source for the number of
occurrences use
the command
syntax
":TRIGGER:OCCURRENCE:SOURCE CHANNEL2"
and to
set
the slope
of
the trigger occurrence use the command syntax
":TRIGGER:OCCURRENCE:SLOPE NEGATIVE".
