Acquisition
Lynx II DSA User's Manual – 7096089 99
• Channel Polarity defines the polarity of the channel advance signal as Positive or
Negative.
• Channel Mode enables (when ON) the external channel advance mode. MCS
acquisition will advance from one channel to the next when a TTL pulse is received
on the CH ADV connector.
• Sweep Polarity defines the polarity of the sweep advance signal as Positive or
Negative.
• Sweep Mode enables (when ON) the external sweep advance mode. MCS
acquisition will wait at the end of the current sweep and advance to the next sweep
when a TTL pulse is received on the SWEEP ADV connector.
The External Control tab describes the MCS-specific external control features. These
features are the same as previously described for Input 1 but they apply to MCS mode.
Calibration Settings
The Calibration settings display the coefficients of the 2nd order equation used by the
spectrum graph to convert X-Axis values from channel numbers to energy or FWHM
when the graph’s X-Units are set to Energy. The calibration model is also displayed.

Proper calibration can be performed using Mirion’s software like Genie 2000, Apex, or
ProSpect.
