Reporting the Setup
The following is a sample response from the :WAVeform? query. In this
case, the query was issued following a *RST command.

access to the waveform data. In the WORD format, the number of data
bytes is twice the number of data points. The number of data points is
the value returned by the :WAVeform:POINts? query (see
the data intrinsically has less than 16 bits of resolution, the data is
left- shifted to provide 16 bits of resolution and the least significant bits
are set to 0. Currently, the greatest intrinsic resolution of any data is
12 bits, so at least the lowest 4 bits of data will be 0. If there is a hole
in the data, the hole is represented by a 16 bit value equal to 0.
Use :WAVeform:BYTeorder (see
significant byte or most significant byte is to be transferred first. The
:BYTeorder command can be used to alter the transmit sequence to
match the storage sequence of an integer in the programming language
being used.
The BYTE format (see
access to the waveform data. If the data intrinsically has more than 8
bits of resolution (averaged data), the data is right- shifted (truncated)
to fit into 8 bits. If there is a hole in the data, the hole is represented
by a value of 0. The BYTE- formatted data transfers over the
programming interface faster than ASCii or WORD- formatted data,
because in ASCii format, as many as 13 bytes per point are transferred,
in BYTE format one byte per point is transferred, and in WORD format
two bytes per point are transferred.
The :WAVeform:BYTeorder command (see
the data format is BYTE.
