<segment_id>,<length>[,<init_value1>[,<init_value2>]]
Command
:TRAC:DEF:WONL
Long
:TRACe:DEFine:WONLy
Parameters
<segment_id>,<length>[,<init_value1>[,<init_value2>]]
 < segment_id > – id of the segment, 1..512k for option SEQ, 1 if not installed
 <length> – length of the segment in samples for direct modes or in I/Q sample
pairs for interpolated modes
 <init_value1> – optional initialization value. For direct modes this is a DAC value.
For interpolated modes this is the I-part of an I/Q sample pair.
 <init_value2> – optional initialization value, only applicable for interpolated
modes. This is the Q-part of an I/Q sample pair.
Parameter Suffix
None
Description
Use this command to define the size of a waveform memory segment. If
<init_value1> is specified (direct modes) or <init_value1> and <init_value2>
(interpolated modes) are specified, all sample values in the segment are initialized. If
not specified, memory is only allocated but not initialized. The segment will be
flagged write-only, so it cannot be read back or stored.
Example
Command
Define a write-only segment with id 1 and length 480 samples.
