REFStat?
FREe
Returns the number
of
free Kbytes
in
the nonvolatile reference memory
as
a
<NR1
> number from
Oto
26.

REFStat? PROTect
Returns a thirty-character string that indicates the protected status of each
of
the reference memories from

SAVeref
REF<1-3>
Command only. Saves the waveform selected by the REFFrom command into
the named reference. REF1, REF2,
and
REF3
are 1 K (1024-point) memory
locations. Any 1 K portion
of
4 K waveform acquisition (from ACQ or
REF4)
may
be
saved as a 1 K reference
in
REF1-REF3; the 1 K portion stored into REF1-
REF3 is determined by the position
of
the active cursor. The saved reference
display is also turned on.
ALL
SAVeref
REF4
Command only.
REF4
is a 4 K (4096-point) memory location. It
is
the only
reference memory for the 2220 and
2221
instruments,
and
as such the REF4
argument may
be
omitted from the SA V command for those instruments.
2230
SAVeref
REF<A-Z>
Command only. Saves the waveform selected by the REFFrom command into
the named reference (REFA-REFZ). Reference waveforms stored
as
4 K records
cannot
be
moved as 1 K records into REF1-REF3; to
be
either displayed or
tranmitted 4 K records must
be
moved into
REF4.
