:WAVeform Commands 34Keysight InfiniiVision 4000 X-Series Oscilloscopes Programmer's Guide 1243:WAVeform:DATA(see page 1428)Query Syntax :WAVeform:DATA?The :WAVeform:DATA query returns the binary block of sampled data pointstransmitted using the IEEE 488.2 arbitrary block data format. The binary data isformatted 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 beenacquired.Another situation where there can be zeros in the data, incorrectly, is whenprogramming over telnet port 5024. Port 5024 provides a command promptand is intended for ASCII transfers. Use telnet port 5025 instead.• 0x01 or 0x0001 — Clipped low. These are locations where the waveform isclipped at the bottom of the oscilloscope display.• 0xFF or 0xFFFF — Clipped high. These are locations where the waveform isclipped at the top of the oscilloscope display.Return Format block data>See Also • For a more detailed description of the data returned for different acquisitiontypes, see: "Introduction to :WAVeform Commands" on page 1235• ":WAVeform:UNSigned" on page 1261• ":WAVeform:BYTeorder" on page 1241• ":WAVeform:FORMat" on page 1245• ":WAVeform:POINts" on page 1246• ":WAVeform:PREamble" on page 1250• ":WAVeform:SOURce" on page 1255• ":WAVeform:TYPE" on page 1260Example Code ' QUERY_WAVE_DATA - Outputs waveform data that is stored in a buffer.' Query the oscilloscope for the waveform data.myScope.WriteString ":WAV:DATA?"' READ_WAVE_DATA - The wave data consists of two parts: the header,' and the actual waveform data followed by a new line (NL) character.' The query data has the following format:'' '' Where:' = #800001000 (This is an example header)
