Master - Slave
This function allows you to select a single instrument as the Master and a second as the Slave. Once started in this mode, a measurement taken from the master instrument will trigger a corresponding measurement from the Slave. The point measurements and the lag time (in seconds) will be displayed with each measurement.
An optional Best-Fit alignment can also be performed as part of this utility by checking the Locate one of the instruments check box. When you press the Done button, after measurements have been taken, this will close the synchronized measurement utility and automatically open a Best-Fit dialog allowing alignment of the selected instrument.
Polling
Polling provides even more options for synchronized measurement applications. It allows multiple instruments to be selected at one time and opens a master control dialog to trigger measurements.
Single Point (Measure Now). When the Measure Now button is pressed it will trigger a point from all of the selected instruments and record those points in the specified point groups.
Stream of Points (Begin). The Stream of Points Begin button will start a continuous measurement from all of the instruments. A time delay can be added between measurements to space the points using the Delay between measurements (sec) option.
Measurement requests from SA are handled separately from measurements triggered directly in the instrument interface. For example, discrete tracker measurements use a specific measurement profile that can be found under Settings>Tracker>SA Interaction>Measurement Requests>Single Point Parameters.
