Minimum and Maximum Measurements
To return the maximum or minimum value of a pulse or ac waveform use:
FETCh:VOLTage:MAXimum? or
FETCh:VOLTage:MINimum?
FETCh:CURRent:MAXimum? or
FETCh:CURRent:MINimum?
High/Low Measurements
The value of the high level or low level of a pulse can also be measured. High and low level
measurements are defined as follows: The instrument first measures the minimum and maximum data
points of the pulse waveform. It then generates a histogram of the pulse waveform using 1024 bins
between the maximum and minimum data points. The bin containing the most data points above the 50%
point is the high bin. The bin containing the most data points below the 50% point is the low bin. The
average of all the data points in the high bin is returned as the High level. The average of all the data
points in the low bin is returned as the Low level. If no high or low bin contains more than 1.25% of the
total number of acquired points, then the maximum or minimum value is returned by these queries.
To return the average value of the high bin, use:
FETCh:CURRent:HIGH? or
FETCh:VOLTage:HIGH?
To return the average value of the low bin, use:
FETCh:CURRent:LOW?
FETCh:VOLTage:LOW?
