Sorting Based on Measured Results (Comparator Function)
Rejecting Excessively Low Measured Results (Low C reject function)
Rejecting Excessively Low Measured Results (Low C reject function)
The E4981A has a function to detect extremely low measured primary
parameter values (Cp or Cs) that are equal to or less than the preset boundary
value as Low C (abnormal measurement status). This is called the Low C reject
function.
When the comparator function is ON, normal sorting judgment will be
performed even if Low C is detected. However, the sorting judgment result
displayed on the screen is LOWC and, on the handler interface, the
/LOWC_OR_NC signal becomes active (low level) in addition to the sorting
judgment signal.
Handler output shares the line for No Contact & Low C Reject and becomes
active when primary parameter is lower than the border value.
