Continuous Streaming
Keysight M8131A 16/32 GSa/s Digitizer User's Guide
Continuous streaming is typically used to stream data over ODI to a
storage system such as a RAID or SSD.
Continuous streaming can also be used to steam data over ODI to a DSP
module (e.g., the M8132A from Keysight) or an AWG (e.g., the M8121A
from Keysight) if the overall latency through the system may vary from e.g.,
power cycle to power cycle.
In case the latency through the system (M8131A Digitizer to M8132A DSP
module to M8121A AWG) must be deterministic, do use
Streaming with Deterministic Latency
Cabling
For continuous streaming, the ODI cable must be connected from the
M8131A (data source) to the data sink (storage system or DSP module or
AWG). It's not necessary to connect a cable to the Sync Output.
Continuous streaming:
•
Start of streaming: Both trigger conditions, triggered and auto are
possible.
•
The length of the data stream is infinite.
•
Stop of streaming: By user.
While capture to waveform memory is active, continuous streaming
NOTE
cannot be started.
Capture to waveform memory:
•
While streaming is inactive, Start & Stop of capture is possible.
•
Start: Both trigger conditions, triggered and auto are possible.
•
Stop: By user or defined number of samples are captured.
•
While continuous streaming is active:
•
It is possible to monitor the traffic that is streamed over the ODI
port.
•
Only capture without waiting for a trigger condition is possible (i.e.,
software start activity on the Trigger Input is ignored).
•
Capture affects only one M8131A module and not multiple modules
in a synchronous system.
•
Mode: Single or repetitive.
