Description
2221 and 2230
ACQuisition SCAn:<ACCpeak
Selects the ACCpeak or AVErage mode for SCAn acquisitions at
0.1
sec/div
to
or AVErage>
5 sec/div. The oscilloscope must
in
NORM or SGL SWP trigger mode to observe
a change
in
the READOUT.
ALL
ACQuisition SMOoth:
<ON
or
OFF>
Applies smoothing to the acquired waveform data when
ON.
2220
ACQuisition TRIGCount: <NR1 >
Sets the number of data points acquired before the trigger point
in
the waveform
record. The range of the <NR1
>number
is
16 to 2048
in
post-trigger
and
2048
to 4080
in
pre- or mid-trigger. The resolution of the <NR1 > value
is
4.
2221
ACQuisition TRIGCount: <NR1 >
Sets the number of data points acquired before the trigger point
in
the waveform
record. The range of the <NR1 > number
is
from
16
to 4080. The setting of the
front-panel TRIG
POS
switch does not limit the range of the trigger point
position within the waveform record. The resolution of the <NR1 > value
is
4.
2230
ACQuisition TRIGCount: <NR1 >
Sets the number of data points acquired before the trigger point
in
the waveform
record. The range of the <NR1 > number depends
on
the record length
and
the
selection of pre- or post-trigger.
In
pretrigger, the <NR1 > range
is
4 to 512 for
1 K records
and
16
to 2048 for 4 K records.
In
post-trigger, the range
is
from
512
to 1020 for 1 K records
and
2048 to 4080 for 4 K records. The resolution of
<NR1 >
is
± 4 counts.
ALL
ACQuisition VECtors:
<ON
or
OFF>
--
Turns point-to-point display vectors
ON
or
OFF.
ALL
ACQuisition WEIght:<NR1 > Sets the number of acquisitions weighted into
an
AVEraged waveform record.
The valid values for
<NR1>
are:
1,
2,
4,
8,
16,
32, 64,128,
and
256. A service
request
is
generated
and
the command
is
ignored if the argument
is
not
one
of
these numbers. If the argument for WElght
is
omitted, <NR1 > reverts to
4.
ALL
ACQuisition?
Returns the settings of the acquisition modes
in
the following short form with
LONG
set to
OFF.
ACQ REP:AVE,HSR:SAM,LSR: PEA,SCA: PEA,ROL:
PEA,
SMO:ON,WEl:4,SWP:1037,NUM:0,POl:4096,
TRIGM:POST,TRIGC:2000,SAV:OFF,DIS:SCA,VEC:ON;
Each
of the acquisition command arguments (except RESet) may
be
queried
separately to find out that argument's status.
ALL
ACQuisition? DISplay
Returns a string of either
ROLi
or SCAn for the present state of the
ROLL/SCAN button. The form of the return
is:
ACQ
DIS:<ROL
or
SCA>;
