REAdout

Turns CRT readout ON or OFF.
MESsage
<NR1> “string’’
Command only. Writes text strings on row <NR1> of the
screen. Legal values for <NR1> are 0 through 16; 1 writes to
the bottom row, 16 writes to the top row, and 0 clears all
messages and restores the default displays. The “string” must
always be within quote marks and is displayed left justified.
Long strings are truncated to approximately 40 characters.
(Characters have proportional spacing.) Displaying multiple
simultaneous messages may cause display flicker and may
exceed display memory capacity.
PLOt STArt ^
Initiates a plot via the GPIB (Option 10) or RS-232-C (Option
12) interface port, or the XY Plotter Port. While the plot is in
progress all commands or queries are ignored except for PLOt
ABOrt, which terminates the plot. If enabled, an OPC SRQ is
sent when the plot completes.
ABOrt
Terminates a plot in progress and returns the instrument to its
previous mode. PLOt ABOrt is the only command or query the
instrument responds to during a plot.
AUTo
[ON]
OFF
Turns AUTo mode ON or OFF. If AUTo is ON, each waveform
is plotted after it is acquired, however, the graticule will only be
plotted once, if GRAt is ON.
GRAt
[ON]
OFF
Determines if a plot will include a graticule image.
FORmat [XY]
HPGI
EPS7
EPS8
TJEt
Defines plot format and output port. FORmat reverts to XY if
port is not configured for plotting. HPGI formats for HP-GLt
compatible plotters. EPS7 and EPS8 format for 7 bit
(low-speed, double density) and 8 bit (high-speed, double
density) Epson" format printers, respectively. TJEt formats for
the Hewlett-Packard ThinkJet” printer.
A GPIB Controller In Charge may issue PLOt STArt to the
oscilloscope, My Listen Address (ML4) to the printer or plotter,
then My Talk Address (MTA) to the oscilloscope to produce a
plot.
SPEed
<NR1> SPEed changes the analog plotter pen speed. <NR1> must
be an integer from 1 through 10. Units are roughly in divisions
per second.
