None
Description
Use this command to define the size of a waveform memory segment. If is
specified (direct modes) or and (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.
Examples
Commands
To set precision mode
TRAC1:DWID WPR
To define a segment with id 1 and length 480 samples. Initialize to sample
value 0.
TRAC1:DEF 1,480,0
To set interpolated mode, interpolation factor 3.
TRAC1:DWID INTX3
To define a segment with id 1 and length 480 samples. Initialize with I/Q
value pair (0,1).
TRAC:DEF 1,480,0,1
:TRACe[1|4]:DEFine:NEW?
Command
Query
:TRACe[1|4]:DEFine:NEW? <length>
[,<init_value1>[,<init_value2>]]
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.
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
