Keysight M8131A 16/32 GSa/s Digitizer User's Guide
This example program (M8131AToM8132ALatency.sln) demonstrates how
to set up the M8131A digitizer and the M8132A DSP for Deterministic
Latency Mode and stream digitized data from the M8131A digitizer to the
M8132A DSP.
In the example, channel 1 of the digitizer is used. The program works with
16GSa/s and 32GSa/s ADC sample rate. For 32GSa/s an additional ODI
connection between M8131A and M8132A is needed. The sample rate
must be set before starting the program.
•
Analog input channel 1 - receives the test signal to be digitized and
streamed to the DSP
•
Trigger output - outputs high-level, when the digitized sample is
positive, else low-level
•
ODI1 to DSP ODI2 - streams digitized samples to the DSP (16GSa/s
and 32GSa/s mode)
•
ODI3 to DSP ODI4 - streams digitized samples to the DSP (32GSa/s
mode)
•
SyncOut to DSP SyncIn - transmits a clock signal to the SyncIn of the
DSP for core clock alignment
•
RefClkOut to DSP RefClkIn - provides the reference clock for the DSP
•
Trigger output - outputs high-level, when the sample received on ODI2
is positive, else low-level
•
ODI2 to digitizer ODI1 - receives the samples from ODI1 of the digitizer
(16GSa/s and 32GSa/s mode)
•
ODI4 to digitizer ODI3 - receives the samples from ODI2 of the digitizer
(32GSa/s mode)
•
SyncIn to digitizer SyncOut - receives the clock signal from the
digitizer for core clock alignment
•
RefClkIn to digitizer RefClkOut - receives the reference clock from the
digitizer
