Wave form Structure 6
INSPECTT"SIMPLE"
The INSPECT? command is also used to examine the measured
data values of a waveform. For an acquisition with 42 points we
get:

These numbers are the fully converted measurements in volts. Of
course, when the data block contains thousands of items the string
will contain many lines.
Depending on the application, you may prefer to have the data in
its raw form as either a BYTE (8 bits) or a WORD (16 bits)
each data value. In this case you must use the relations given below
in association with the WAVEFORM? command to interpret the
measurement. The command might then say:
INSPECT? "SIMPLE",BYTE
The examination of data values for waveforms with two data arrays
can be done as follows:
INSPECT? "DUAL" to get pairs of data values on a single line
INSPECT? "DATA_ARRAY_I"
to get the values of the first data array
INSPECT? "DATA ARRAY 2"
- to ge~the values of the second data array
It is also possible to examine just a part of the waveform or a
sparsed form of the waveform. This is controlled with the WAVE-
FORM_SETUP command mentioned later in this section.
The INSPECT? command has only a query form. It cannot be
used to send a waveform back into the oscilloscope. It is also a very
verbose way in which to send the information and is not very fast.
Users who need speed or the ability to send the waveform back to
the instrument should use the WAVEFORM commands.
BASIC users might find it convenient to combine the capabilities
of the inspect facility with the waveform query command in order
to construct files containing a human and BASIC readable version
of the waveform descriptor together with the full waveform in a
format suitable for retransmission to the instrument. This can be
