Waveform Commands
BYTeorder
BYTeorder
Command :WAVeform:BYTeorder {MSBFirst | LSBFirst}
The :WAVeform:BYTeorder command selects the order in which bytes are
transferred to and from the oscilloscope using WORD and LONG formats. If
MSBFirst is selected, the most significant byte is transferred first. Otherwise,
the least significant byte is transferred first. The default setting is MSBFirst.
Example
This example sets up the oscilloscope to send the most significant byte first
during data transmission.
10 OUTPUT 707;":WAVEFORM:BYTEORDER MSBFIRST"
20 END
Query :WAVeform:BYTeorder?
The :WAVeform:BYTeorder? query returns the current setting for the byte order.
Returned Format
[:WAVeform:BYTeorder] {MSBFirst | LSBFirst}<NL>
Example
This example places the current setting for the byte order in the string variable,
Setting$, then prints the contents of the variable to the computer's screen.
10 DIM Setting$[10]!Dimension variable
20 OUTPUT 707;":WAVEFORM:BYTEORDER?"
30 ENTER 707;Setting$
40 PRINT Setting$
50 END
MSBFirst and LSBFirst
The data transfer rate is faster using the LSBFirst byte order.
MSBFirst is for microprocessors like Motorola’s, where the most significant byte
resides at the lower address. LSBFirst is for microprocessors like Intel’s, where the
least significant byte resides at the lower address.
