8 Coordinating Multiple PXIe
Oscilloscope Modules
Step 1: (Optional) Update the Calibration Factors / 46
Step 2: Set Up the Slave Modules / 49
Step 3: Set Up the Master Module / 50
Step 4: (When Necessary) Connect Chassis Bus Segments / 51
Step 5: (Recommended) Phase-Lock Oscilloscope Sampling Clocks / 54
Step 6: (Optional) Turn On Sync Mode / 55
Step 7: Make Coordinated Acquisitions / 60
You can synchronize acquisitions between multiple M924xA oscilloscope modules
by using the PXI Trigger Menu to set up coordinated arming and triggering.
Among all the oscilloscope modules to be synchronized, one module must be the
master and all other modules must be slaves. The
PXI Trigger Mode
softkey makes
the master or slave selection for a module (or turns off PXI triggering for the
module, making it a standalone module).
The Trigger Menu on the master oscilloscope module is used to define the trigger
condition. The master module outputs its trigger signal to one of the chassis
PXI_TRIG lines (0-7). All slave modules receive the trigger signal over the same
PXI_TRIG line, and their Trigger Menus simply show that they are PXI slaves.
There is a separate "armed" signal from each slave module so that the master can
wait until each slave is ready before triggering. The remaining PXI_TRIG lines can
be used for the arm lines from the slave modules. With arming control, there can
be up to seven slave modules. (With software arming in remote programs, there
can be more than eight modules in a multiple-module system.)
Arming control is not required; however, if it is not used, a slave module may miss
trigger events from the master module (because the master module may send
triggers when the slave module is not armed).
