Command Syntax
Table 2-4: End o
f Message Terminator
Symbol Meaning
<EOM>
Message termi
nator
The end-of-message terminator must be the END message (EOI asserted
concurrently with the last data byte). The last data byte may be an ASCII line
feed (LF) character.
This oscilloscope does not support ASCII LF only message termination. The
oscilloscope 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: Channel Mnemonics
Symbol Meaning
CH<x> A channel specifier; <x> is 1 through 4.
Table 2-6: Cursor Mnemonics
Symbol Meaning
CURSOR<x>
A cursor selector; <x> is either 1 or 2.
POSITION<x>
A cursor selector; <x> is either 1 or 2.
HPOS<x>
A cursor selector; <x> is either 1 or 2.
Math Specifier Mnemonics
Commands can specify the mathematical waveform to use as a mnemonic in
the header.
Table 2-7: Math Specifier Mnemonics
Symbol Meaning
Math<x>
A math waveform specifier; <x> is 1.
