5 Commands by Subsystem

:WAVeform:SOURce

(see page 798)

Command Syntax

:WAVeform:SOURce <source>

<source> ::= {CHANnel<n> | FUNCtion | MATH | SBUS} for DSO models

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

| MATH | SBUS} for MSO models

<n>::={1|2|3|4}forthefour channel oscilloscope models

<n> ::= {1 | 2} for the two channel oscilloscope models

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

digital pod, digital bus, 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 (SBUS), ASCii is the

only waveform format allowed.

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 640).

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 timestamps and hexadecimal bus values, for example:

- 5.000000000000e- 08,0x1938,- 4.990000000000e-08,0xff38,...

Query Syntax

:WAVeform:SOURce?

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

the WAVeform commands.

NOTE

MATH is an alias for FUNCtion. The :WAVeform:SOURce? Query returns FUNC if the source

is FUNCtion or MATH.
