Details of Calculation
The following are explanations given for traces C, F, and G.
Trace C: CALCULATE C
LOG MATH
This key is used to perform LOG calculations on trace-to-trace data and write the results
to trace C. Calculations can be applied to trace A and trace B. If both traces selected
for calculation are set to “BLANK”, then the sub-scale is displayed on the left side of the
screen. Otherwise it is displayed on the right side. The calculation results are displayed
in the sub-scale.
C=A-B(LOG) Subtracts trace B from trace A in LOG form.
C=B-A(LOG) Subtracts trace A from trace B in LOG form.
C=A+B(LOG) Adds trace A and trace B in LOG form.
LIN MATH
This key is used to perform linear calculations on trace-to-trace data and write the results
to trace F. Calculations can be applied to trace A and trace B. The calculation results are
displayed in the main scale.
C=A+B(LIN) Adds trace A and trace B in linear form.
C=A-B(LIN) Subtracts trace B from trace A in linear form.
C=B-A(LIN) Subtracts trace A from trace B in linear form.
C=1-k(A/B)
Given Trace A and Trace B, calculates 1-k(A/B).
Calculates 1-k × (trace A/Trace B) (linear value), and writes the results to trace C.
The coefficient k may be changed in the range of 1.0000 to 20000.0000 (in steps
of 0.0001) using the rotary knob, arrow keys, or numeric keypad.
The coefficient k setting applies to both the <C=1-k(A/B)> key and <C=1-k(B/A)>
key. The trace display on the side of the data area changes to “1-k(A/B)”.
C=1-k(B/A)
Given Trace A and Trace B, calculates 1-k(B/A).
Calculates 1-k x (Trace B/Trace A) (linear value), and writes the results to trace C.
The trace display on the side of the data area changes to “1-k(B/A)”.
