5-48 Remote Operation
If
RASTer
is
selected the scan rate
can
be adjusted by the selected reference
oscillator.
The
raster scan frequency is controlled by the :FREQuency:RASTer
program message. Raster mode would be used to play back arbitrary waveforms
which typically define a complex pattern
of
amplitude versus time. The user may
not want to use the filter in this mode because they may be generating stair step or
pulse patterns that are meant to have sharp edges.
TRACe:POINts
<trace_name>,<numeric_value>
Sending
this
pro
gram
message
resizes the
trace
whose
name
is
specified
by
<trace_name>. The new size is specified by the second integer parameter.
TRACe:POINts?
<trace
name>
Sending this query returns the size
of
the specified trace.
TRACe:REName
<trace
name>
<trace
name>
- -
Sending this program message
al10ws
you to rename a trace. The first trace name
identifies the existing trace, and the second trace name is the
new
name.
TRACe:SELect
<trace
name>
Sending this program message selects one
of
the defined traces stored in memory.

This program message sets the number
of
times to cycle through a trace after a
trigger is received. The COONt value ranges from 1 to 1,048,575 for waveforms.
TRIGger:GATE[:STATe]
<ON
1 OFF>
This
program
message
to
enable
the
gate
mode.
Gate
the
Model
395
using
TRIG:IMM, *TRG,
or
external trigger source.
TRIGger[:IMMediate]
This
program
message triggers the instrument, independently
of
which
trigger
source was selected.
If
the TRIG:GATE
ON
is selected, this command will gate the
unit.
TRIGger[:IMMediateJ
:STATe
<Boolean>
This program message gates on and gates
off
the unit. Sending 1 or
ON
enables
the generator while
0
of
OFF
(the default) disables the generator.
TRIGger:POLarity
<POSitive
1
NEGative>
This program message selects the active trigger level.
