modules by automatically deskewing all channels to a user-designated
reference channel, with the common deskewed reference plane being
the input channel connectors on the acquisition module. A very high
level of accuracy is maintained by using a fast reference signal and
averaging for precision.
SystemSkew Cal
For a given LabMaster setup consisting of more than one acquisition
module, this calibration provides the fastest and easiest way to
eliminate the static skew caused by all PCIe interconnection cables and
align trigger positions on all modules. The SystemSkew Cal need only be
performed once at initial setup as long as neither the cables nor the
acquisition modules change. If the LabMaster system you're using has
only one acquisition module, a SystemSkew Cal provides no value.
During SystemSkew Cal, you are instructed to connect the Fast Edge
output to one channel on each acquisition module in a prescribed
manner. All static skew adjustments are saved in a calibration folder.
The values for this static skew calibration are not displayed in the
ChannelSync Cal dialog. If the LabMaster system on startup detects a
configuration change (e.g. a different serial number acquisition module
connected to a certain PCIe slot), a pop-up dialog will appear warning
the user to perform a new SystemSkew Cal.
1.
From the menu bar, choose Vertical > Channel <#> Setup. Touch
the ChannelSync Cal tab to the right of the C<#> tab.
2.
