ust consist of a valid IEEE488.2 message unit, which may

not appear in a message preceded by a colon, comma, or a command or query

program header.

the alias name may not appear in a message followed by a colon, comma,

or question mark.

an alias name must be distinct from any keyword or keyword short form.

an alias name cannot be redeﬁned without ﬁrst being deleted using one of

the alias deletion functions.

alias names do not appear in response messages.

Table 2-17: ARB Commands

Command Description

AFG:ARBitrary:ARB<x>:DATE? Returns the date that the data in the speciﬁed arbitrary waveform slot 1-4 was s aved.

AFG:ARBitrary:ARB<x>:LABel Sets (or queries) the waveform label for arbitrary waveform slots 1- 4.

argument, w ith the number of points optionally speciﬁed by the NR1 argument. To query the

arbitrary waveform function set by this command, use AFG:ARBitrary:EMEM:FUNCtion?

AFG:ARBitrary:EMEM:POINTS Speciﬁes which points to load into the AFG arbitrary waveform edit memory.

AFG.ARBitrary.EMEM.POINTS.BYTEORDerThis command speciﬁes the byte order for the :AF G:AR Bitrary :EM E M :POINTS? query

when the :AFG :ARB itrary:EMEM:ENCDG is set to BINary and when binary block data is

sent for the :AFG:ARB itrary:EMEM:PO INTS command.

AFG:ARBitrary:EMEM:POINTS:ENCdg This command speciﬁes the data encoding format for the AFG:ARBitrary:EMEM:POINTS

query (either AS CII or binary).

Bus Command Gr

oup

Use the Bus commands when working with serial or parallel bus measurements.

Bus commands let you specify the bus number: (B1-B4), except for MDO3000,

which has onl

y two buses (B1-B2).

B1 – B4 for MSO/DPO/MDO4000/B models

B1 – B3 for MDO4000C models

B1 – B2 for MDO3000 models

Parallel bus trigger and analysis functionality is included standard withtheMSO

and MDO Series. All other bus triggers require installation of an application

module.

A table is available that lists all commands enabled by each application module

(See page H-1, List of Beta Commands and Features.)

For I

C or SPI bus signals, install the DPO4EMBD application module,

except for MDO3000 models, which require MDO3EMBD.

For RS-232, RS-422, RS-485, or UART bus signals, install the DPO4COMP

module, except for MDO3000 models, which require MDO3COMP.

For I

S, Left Justiﬁed (LJ), Right Justiﬁed (RJ), or TDM bus signals, install

the DPO4AUDIO module, except for MDO3000 models, which require

MDO3AUDIO.

For CAN, CAN FD, or LIN bus signals, install the DPO4AUTO or

DPO4AUTOMAX module, except for MDO3000 models, which require

MDO

3AUTO.

For FlexRay bus signals, install the DPO4AUTOMAX module, except for

O3000 models, which require MDO3FLEX.

For Ethernet signals, when tested with the MDO4000/B/C and

SO/DPO4000B, install the DPO4ENET module. Note that ≥350 MHz

bandwidth models are recommended for 100BASE-TX.

For MIL-STD-1553 or ARINC429 bus signals, install the DPO4AERO

module, except for MDO3000 models, which require MDO3AERO.

For USB bus signals, install the DPO4USB module, except for

MDO3000 models, which require MDO3USB. Note that 1 GHz bandwidth

models are recommended for high-speed (HS) USB.

NOTE. The Search Command Group and the Trigger Command Group also

contain bus-related commands.
