8.22.10 :TRACe[1|2]:DEFine:WONLy:NEW? <length>[,<init_value1>[,<init_value2>]]

Command

:TRAC:DEF:WONL:NEW?

Long

:TRACe:DEFine:WONLy:NEW?

Parameters

<length>[,<init_value1>[,<init_value2>]]

 <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 query 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. If the query was successful, a new <segment_id>

will be returned. The segment will be flagged write-only, so it cannot be read back or

stored.

Example

Query

Define a write-only segment with id 1 and length 480 samples.
