Data transfer DTFORM
Command/Query
DESCRIPTION The DTFORM command defines the format used to transfer
waveform data. The DTWAVE? query transfers the waveform
data. The DTFORM? query returns the defined waveform
data transfer format. For more information on the
waveform data transfer format, see the DTWAVE? query.
COMMAND SYNTAX DTFORM <form>
<form>:={ASCII, BYTE, WORD}
ASCII := transfer waveform data in ASCII mode.
BYTE := transfer waveform data in binary mode and use
BYTE format.
WORD := transfer waveform data in binary mode and use
WORD format. Byte order in the word is able to be
specified by DTBORD command.
QUERY SYNTAX DTFORM?
RESPONSE FORMAT <form>
The waveform data transfer format is identified in
<form>.
REMARKS
In some cases, waveform transfer format is fixed in spite of DTFORM.
