U
2230
REFOrmat
VGAin
:
<
NR3 >
Changes the

reference
target and
channel
designated by
REFOrmat TARget and REFOrmat CHAnnel . This command is not valid for XY
waveforms . The
maximum < NR3
>
value
permitted is the
equivalent of 13
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

:
< NR2 >
Adjusts
the
vertical
position
of the
reformatting target
waveform . The
valid range
of < NR2 >
is £ 10
divisions from the
original position 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

2220 and 2221
.
2230
REFDisp ? REF < 13 >
Returns the
status
of
the
named

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 ) .

0.2E
+
O ,
MOD :
CH1 ;
Each

REFStat
?
FIL
Returns
a
thirty -
number string that
indicates

memories
from
REF1 to
REFZ
.
The numbers
