Keysight M8131A 16/32 GSa/s Digitizer User’s Guide 19
Introduction 1
Figure 1 on page 19 illustrates the front panel of the M8131A instrument.
Figure 1 M8131A front panel
The M8131A front panel include the following input/output ports:
Inputs/Outputs
• Input - The four analog input ports (In 1/2/3/4) can be used to receive
the analog data.
• ODI - The four Optical Data Interface ports (ODI 1/2/3/4) can be used
for optical data streaming.
• Trig In - The Trigger Input can be used for external triggering.
Triggering source can be an external pulse generator connected. This
will be used only when the trigger source is “Trigger Input”.
• Trig Out - The Trigger Output can be used to trigger external
instruments or DUTs.
• Sync In - The Sync Input can be used to synchronize two or more
modules to a common system clock. It is connected to the Sync Out of
an other module.
• Sync Out - The Sync Output can be used to synchronize two or more
modules to a common system clock. It is connected to the Sync In of an
other module.
• Sample Clk In - The Sample Clock Input can be used, if an external
clock source shall be used to clock the analog to digital to converters.
• Sample Clk Out - The Sample Clock Output can be used to output the
clock signal from the internal sample clock or the sample clock input.
When an internally generated sample clock of the M8131A’s is used,
the Sample CLK Out must be connected with Sample Clk In with a
semi-rigid cable as shown in the Figure 2 on page 20. However, if an
external 8 GHz sample clock is used, the semi-rigid cable is not
required.
