Command Syntax
If the header is
off:
FULL;DOTSONLY
1. Set commands and queries m ay be concatenated in the same message. For
example,
ACQuire:MODe SAMple;NUMAVg?;STATE?
is a valid message that sets the acquisition mode to sample. The message then
queries the number of acquisitions for averaging and the acquisition state.
Concatenated commands and queries are executed in the or der received.
Here are some invalid concatenations:
DISPlay:STYle DOTsonly OFF;ACQuire:NUMAVg 8 (no colon before
ACQuire)
DISPlay:GRAticule FULL;:STYle DOTSONLY OF F (extra colon before
STYle.
DISPlay:GRAticule FULL;:*TRG (colon before a star (*) command)
ACQUIRE:FASTACQ:PALETTE TEMPerature;FA STAcq:STATE ON (levels
of the mnemonics are different; either remove the second use of
FASTACQ:
or place :ACQUIRE in front of FASTAcq:STATE)
Terminating
This documentation uses <EOM> (End of Message) to represent a message
terminator.
Table 2-4: End of Message Terminator
Symbol Meaning
<EOM>
Message terminator
The end-of-message terminator m ust be t he 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, CH4, CH5, CH6, CH7, or CH8
depending on the number of FlexChannels in your instrument. You u se these
mnemonics in the command just as you do any other mnemon
ic. 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>.
