Waveform:source - Agilent Technologies InfiniiVision 2000 X-Series Programmer's Manual

:WAVeform:SOURce

Command Syntax
:WAVeform:SOURce <source>
<source> ::= {CHANnel<n> | FUNCtion | MATH | WMEMory<r> | SBUS1}
<source> ::= {CHANnel<n> | POD{1 | 2} | BUS{1 | 2} | FUNCtion
<n> ::= 1 to (# analog channels) in NR1 format
<r> ::= {1 | 2}
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, and FFT (Fast
Fourier Transform) operations.
When the :WAVeform:SOURce is the serial decode bus (SBUS1), 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
• When BUS1 or BUS2 is selected as the waveform source, you can
Query Syntax
:WAVeform:SOURce?
The :WAVeform:SOURce? query returns the currently selected source for
the WAVeform commands.

choose the BYTE, WORD, or ASCii formats (see
page 639).
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.
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,...
