Using the Measurement Calculator / Register Math Function. Contd.
Clip Function
Use this to create a threshold level. A ZERO value clip causes software to ignore clipping and resume normal calculator
mode.
For example lets say the you wish to not include data points smaller than some low level value such as <-50dBM.
Enter the value -50 into the constant window aUnderstanding the Register Math Functions nd highlight “Clip”. This
will operate on only the data from the first set (left of the +-*/). Any magnitude values LESS that the clip value will be set
EQUAL to the clip value.
Notice: the plotting functions will be affected by the clip value. Use this to scale and expand the plots. Notice also that
the calculator can be used to change the plot scales from linear to log or to add offset to measurements.
TERM 1 MULTIPLIER Works with
LINEAR +,-
linMag +,-,*,/
LogMag +,-,*,/
TERM 2 MULTIPLIER All functions above plus Constant
IMPORTANT: Not all combinations of Math are possible. Be sure you
have the same size data array
