the 24th data "FF", convert to decimal is "255" (Hexadecimal converted
to decimal). Then minus 255, the code value is 0.
The first point of wave data voltage value = 0*(1/25) = 0V.
Step 3: Calculate the time value of the data point.
Using the formula: time value(S) = - (timebase*grid/2).
timebase: The timebase value.
grid: The grid numbers in horizontal direction.
The picture above as an example:
Send command
Return
TDIV 5.00E-09S
Get the current timebase: timebase = 5.00E-09S.
The time value of the first data point: time value = - (5.00E-09*14/2) = -
35.00E-09(s) = -35(ns).
Send command
Return
SARA 5.00E+08Sa/s
Get the current sampling rate: sampling rate= 500MSa/s.
Send command
Return
SANU 3.50E+01pts
Get the number of sampling points: points number = 35pts.
The interpolation multiplier: interpolation multiplier = length of the block
/ points number = 700/35 = 20
The time interval: time inter = 1/ sampling rate/ interpolation multiplier =
0.1ns.
