Header path
Commands or queries that apply to a subsection of the oscilloscope, such as a single input channel,
must have their headers prefixed with a path name indicating the channel or trace recipient of the
command. It's recommended to always use header paths to minimize the risk of error if the command
order changes.
The header path normally consists of an abbreviated path name followed by a colon ( : ) immediately
preceding the command header.
C1:OFST -300 MV
The target waveform trace is specified using the following header path names:
Header Path Name Oscilloscope Reference
C1, C2 Channels 1 and 2
C3, C4 Channels 3 and 4 (on four-channel models)
M1,M2,M3,M4,M5,M6,M7,M8,M9,M10 Memory Units 1 through 10
TA, TB, TC, TD FFT of the corresponding Channel 1-4; in some commands
also used to refer to zooms.
EX, EX5 External trigger
LINE
LINE source for trigger
NOTE: Header paths TA-TD are used only to refer to the FFT of the channel, or in some cases to expanded traces
(zooms).
Header paths need only be specified once until the path changes. Subsequent commands without
header paths are assumed to refer to the most recently defined path:
C2:VDIV?;C2:OFST?
is equivalent to
C2:VDIV?;OFST?
Header
The header is the mnemonic form of the operation to be performed by the oscilloscope. Most headers
have a more easily recognized
long form
and a
short form
for better transfer and decoding speed. The
two can be used interchangeably:
TRIG_MODE AUTO
is equivalent to
TRMD AUTO
Some command or query mnemonics are imposed by the IEEE 488.2 standard. All these mnemonics
begin with an asterisk
