: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
• 0xFF or 0xFFFF — Clipped high. These are locations where the

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
