4.11 Calculation functions
The FRA5087 has the following capabilities: to apply various calculation operations to the
frequency characteristics measured by the FRA5087, to display the calculation results on the LCD
screen and to save/store the calculation results in USB flash drive.
There are three (3) types of calculation operations available for the FRA5087, which are as
follows:
・
[+ -   ] : Four rules of arithmetic
・
[d/dt
：∫
dt] : Differentiation and integration
・
[OPEN/CLOSE] : Open-loop and closed-loop conversion
Use the menu [Calc.] to set calculation operations.
Another calculation operation can be applied to a result obtained through a calculation operation.
4.11.1 Operation of four rules of arithmetic
There are three types of operations of four rules of arithmetic as follows: calculation between data
values, calculation between a data value and a numerical value, and calculation between
numerical values.
Use the menu window [Calc.] [+ -
  ] to set the operation of the four rules of arithmetic.
[DATA1]
TAG(measurement result
or calculation result)
or
CONSTANT(constant value,
real number)
or
IMAGINARY(constant value,
imaginary number)
[MODE]
＋
－
×
÷
[DATA2]
＝
[ANSWER TAG]
TAG0～6
TAG(measurement result
or calculation result)
or
CONSTANT(constant value,
real number)
or
IMAGINARY(constant value,
imaginary number)
Fig. 4-18 Functions/operations of four rules of arithmetic
Select one from among 0 to 6 to set the TAG number for [DATA1] or [DATA2]. The number 0
indicates the currently displayed TAG number. The measurement results are always contained in
Tag 1.
Press the function key [START] to start calculation and to display the calculation result in the
ANSWER TAG.
Complex numbers can be produced by adding constant values of real and imaginary numbers. If
you need imaginary or complex numbers to use them in calculation operations of differentiation,
integration or open- and closed-loop conversion, produce them by using calculation operations of
four rules of arithmetic.
