Keysight M8121A Arbitrary Waveform Generator User Guide
•
Flow Control - Flow control is sometimes needed to control the
flow of data over the ODI link. Select "In Band" when streaming
data from a source that is not digitizing data real-time, such as
a RAID or DSP module. Select "None" when streaming data
from a digitizer that is digitizing data real-time. If the sample
clock is shared with the real-time data source, "In Band" or
"None" can be used.
•
Link Channel - Currently, the setting of -1 is supported.
•
Packet Format - The M8121A accepts data without any header
information, so only "None" is available. Other options are
reserved for future use.
•
Class ID - The Class Id should match the format on the Clock
and Output tab. The incoming data format defined by the Class
ID should adhere to the ODI standard.
•
Packed 12 bit: This can be used when the Mode on the
Clock and Outputs tab is "12 bit direct". The data should be
streamed from the data source in packed 12 bit samples.
•
Real 12 bit + marker: This can be used when the Mode on
the Clock and Outputs tab is "12 bit direct". The data
should be streamed from the data source in 16 bit samples
of which the 12 most significant bits is the sample, and the
2 least significant bits are the markers.
•
Real 14 bit + marker: This should be used when the Mode
on the Clock and Outputs tab is "14 bit direct". The data
should be streamed from the data source in 16 bit samples
of which the 14 most significant bits is the sample, and the
2 least significant bits are the markers.
•
I/Q 15 bit + marker: This should be used when the Mode on
the Clock and Outputs tab is any of the Interpolated modes.
The data should be streamed from the data source in
interleaved (alternating I and Q) 16 bit samples of which the
15 most significant bits is the sample, and the 1 least
significant bit is the marker.
•
ODI Activate – This button will reactivate the ODI port. This can
be used to attempt to resynchronize the M8121A ODI port with
that of a ODI data producer. ODI statistics are reset whenever
the ODI port is activated.
