There are two different deskew calibrations that can be performed. Both
permit quick and easy deskew of all of the channels in all LabMaster
acquisition 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 the cables or the acquisition modules do not
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.
