:WAVeform:DATA

Query Syntax
:WAVeform:DATA?
The :WAVeform:DATA query returns the binary block of sampled data points
transmitted using the IEEE 488.2 arbitrary block data format. The binary data is
formatted according to the settings of the :WAVeform:UNSigned,
:WAVeform:BYTeorder, :WAVeform:FORMat, and :WAVeform:SOURce commands.
The number of points returned is controlled by the :WAVeform:POINts command.
In BYTE or WORD waveform formats, these data values have special meaning:
• 0x00 or 0x0000 — Hole. Holes are locations where data has not yet been
• 0x01 or 0x0001 — Clipped low. These are locations where the waveform is
• 0xFF or 0xFFFF — Clipped high. These are locations where the waveform is
Return Format
<binary block data><NL>

Another situation where there can be zeros in the data, incorrectly, is when
programming over telnet port 5024. Port 5024 provides a command prompt
and is intended for ASCII transfers. Use telnet port 5025 instead.
