R&S Signal Generator Waveform and List Format
Setting parameters:
Length
Specifies the number of bytes in a WAVEFORM tag and is calculated
as follow:
Length = Number of I/Q pairs * 4 (2 bytes per I and 2
bytes per Q value) + 1 byte (the length of the #)
IxQx
Example:
IxQx… represents binary data (16-bit signed integer in 2's complement
notation) containing the I and Q component alternately
and starting with the I component. Each component consists of
two bytes in Little endian format representation, i.e least significant
byte (LSB) first.
The values of the two bytes in an I component and a Q component
are in the range 0x0 to 0xFFFF (-32767 to +32767). This value is
transferred to the D/A converter.
This tag is also used to store multi segment waveforms. The I/Q
streams of the individual waveforms are directly concatenated to
one collectively waveform I/Q stream.
The number of segments and the start offset and length of the
individual segments inside the total waveform I/Q stream is determined
by the additional tags ​MWV_SEGMENT_COUNT, ​
MWV_SEGMENT_START and ​MWV_SEGMENT_LENGTH.
Further MWV_SEGMENT_... tags are also available, i.e. for level
and clock information etc.
One segment waveform
{WAVEFORM-401:#I 0 ,Q 0 ,I 1 ,Q 1 ,I 2 ,Q 2 ,...I 99 ,Q 99 }
100 I/Q pairs with 4 bytes each are transmitted - none multi segment
