Command Syntax
Here are some in
valid concatenations:
DISplay:PERSistance:RESET ;ACQuire:NUMAVg 10 (no colon before
ACQuire)
DISplay:GRAticule FULl;:FILTer SINX (extra colon before FILT
er;
use
DISplay:GRAticule FULl;FILTer SINX instead)
DISplay:PERSistance:RESET ;:*OPC (colon before a star (*) command)
DISplay:COLOr:MATHCOLOr DEFAULT;COLOr:REF COLOr INHERIT (levels
of the mnemonics are different; either remove the second use of
COLor or place
:DISPlay: in front of COLOr:REFCOLOr INHERIT)
Terminating
This documentation uses <EOM> (End of message) to represent a mess age
terminator.
Table 2-4: End of Message Terminator
Symbol Meaning
<EOM>
Message terminator
The end-of-message terminator must be the END message (EOI asserted
concurrently with the last data byte). The last data byte may b e an ASCII linefeed
(LF) character.
This instrument does not support ASCII LF only message termination. The
instrument always terminates outgoing messages with LF and EOI.
Constructed Mnemonics
Some header mnemonics specify one of a range of mnemonics. For example, a
channel mnemonic can be CH1, CH2, CH3, or CH4. You use these mnemonics
in the command just as you do any other mnemonic. For example, there is a
CH1:POSition command, and there is also a CH2:POSition command. In the
command descriptions, this list of choices is abbreviated as CH<x>.
Cursor Position
Mnemonics
When cursors are displayed, commands may specify which cursor of the pair to
use.
Table 2-5: Cursor Mnemonics
Symbol Meaning
CURSOR<x>
A cursor selector; <x> is either 1 o r 2.
POSITION<x>
A cursor selector; <x> is either 1 o r 2.
HPOS<x>
