:WAVeform Commands 34

Keysight InfiniiVision 3000T X-Series Oscilloscopes Programmer's Guide 1111

:WAVeform:SOURce

(see page 1276)

Command Syntax

:WAVeform:SOURce <source>

<source> ::= {CHANnel<n> | FUNCtion<m> | MATH<m> | WMEMory<r>

| SBUS{1 | 2}} for DSO models

<source> ::= {CHANnel<n> | POD{1 | 2} | BUS{1 | 2} | FUNCtion<m>

| MATH<m> | WMEMory<r> | SBUS{1 | 2}}

for MSO models

<n> ::= 1 to (# analog channels) in NR1 format

<m> ::= 1 to (# math functions) in NR1 format

<r> ::= 1 to (# ref waveforms) in NR1 format

The :WAVeform:SOURce command selects the analog channel, function, digital

pod, digital bus, reference waveform, or serial decode bus to be used as the source

for the :WAVeform commands.

Function capabilities include add, subtract, multiply, integrate, differentiate, and

FFT (Fast Fourier Transform) operations.

When the :WAVeform:SOURce is the serial decode bus (SBUS1 or SBUS2), ASCii

is the only waveform format allowed, and the :WAVeform:DATA? query returns a

string with timestamps and associated bus decode information.

With MSO oscilloscope models, you can choose a POD or BUS as the waveform

source. There are some differences between POD and BUS when formatting and

getting data from the oscilloscope:

• When POD1 or POD2 is selected as the waveform source, you can choose the

BYTE, WORD, or ASCii formats (see ":WAVeform:FORMat" on page 1101).

When the WORD format is chosen, every other data byte will be 0. The setting

of :WAVeform:BYTeorder controls which byte is 0.

When the ASCii format is chosen, the :WAVeform:DATA? query returns a string

with unsigned decimal values separated by commas.

• When BUS1 or BUS2 is selected as the waveform source, you can choose the

WORD or ASCii formats (but not BYTE because bus values are always returned

as 16-bit values).

When the ASCii format is chosen, the :WAVeform:DATA? query returns a string

with hexadecimal bus values, for example: 0x1938,0xff38,...

Query Syntax

:WAVeform:SOURce?

The :WAVeform:SOURce? query returns the currently selected source for the

WAVeform commands.
