Commands
Description
2230
REFOrmat
VGAin:<NR3>
Changes the vertical gain of the reference target and channel designated
by
REFOrmat T ARget
and
REFOrmat CHAnnel. This command
is
not valid for XY
waveforms. The maximum
<NR3>
value permitted
is
the equivalent of
±3
detent positions
of
the VOLT/DIV switch
(in
a 1-2-5 sequence).
An
execution
error status byte is generated either if the asked-for setting is out of the
maximum change range or if it is not a 1-2-5 sequence setting.
2230
REFOrmat
VPOsition:<NR2>
Adjusts the vertical position of the reformatting target waveform. The valid range
of
<NR2>
is ± 10 divisions from the original display position (before any
reformatting) with a resolution
of
one displayed bit.
ALL
REFDisp?
Returns the status of the
REF1
reference memory location as
ON,
OFF,
or
EMPTY for the 2230; returns the status of
REF4
for the 2220
and
2221.
2230
REFDisp?
REF<1-3>
Returns the status of the named 2230 reference memory location
as
ON,
OFF,
or EMPTY.
ALL
REFDisp? REF4
Returns the status
of
REF4
as
ON,
OFF,
or EMPTY. For the
221
0
and
2221
instruments, the default argument of
REF4
is not needed.
ALL
REFFrom? Query returns the selected source of waveform data for the SAVeref command.
The reply will
be
ACQ for the 2220
and
2221
; for the 2230 it may
be
from ACQ
or any REFerence from (REF1-REF4)
and
(REFA-REFZ).

2230
REFOrmat?
Returns the status of the REFOrmat command
and
query arguments. A sample
return is:
REFO
TAR:REF4, CHA:CH2,VGA:0.5E+0, VPO:+3.96, HMA:OFF,
BAS:0.2E+0,MOD:CH1;
Each
of
the command arguments may
be
individually
queried for their status with respect to the REFOrmat T ARget
and
CHAnnel
reference waveform.
2230
REFOrmat? BASegain
Returns the vertical gain setting at which the REFOrmat T ARget waveform was
acquired
as
an
<NR3>
number.
2230
REFOrmat? MODe
Returns the vertical mode
in
which the REFOrmat T ARget waveform was
acquired (CH1, CH2, ADD, CHOP, ALT, or
XY).
2230
REFStat?
FILI
Returns a thirty-number string that indicates the fill status of each of the
reference memories from
REF1
to REFZ. The numbers are 0 (empty),
1,
2,
4,
or
8
and
indicate the stored waveform record
in
Kbytes.
