Description
Four arithmetic
operations (+, −,
×
,
÷
)
Performs calculations using operators specified from the four arithmetic operations,
which consists of addition (+), subtraction (−), multiplication (×), and division (÷).
Multiplication signs (×) and division signs (÷) are represented as asterisks (*) and
slashed (/), respectively.

k
: Number of moving point (1 to 5000)
Specify the constant
k
following a comma. Example: Calculating 100-point moving
averages of the Z1 waveform MOV(Z1,100)
For each
k

points of data at the beginning and end of the calculation interval, the
instrument performs calculations by plugging in zero for data-missing parts.
Parallel move in the
time axis direction
(SLI)
This function requires the number of moving points to be specified in the second
parameter
k
.
The instrument translates a waveform in the time-axis direction by the specified moving
points.

100 points SLI(Z1,100)
Note: If the instrument finds non-data parts at the beginning or end of the calculation
interval after translating a waveform, the instrument specifies zero-volt voltage
there.
