Operator's Manual

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
