code value: The decimal of wave data.
Note: If the decimal is greater than "127", it should minus 255. Then the
value is code value. Such as the wave data is "FC" convert to decimal is
"252". So the code value is 252-255 = -3.
vdiv: The Volts/div value.
voffset: The voltage position value.
The picture above as an example:
Send command
Return
C1:VDIV 5.00E-01V
Get the current Volts/div values: vdiv = 0.5V.
Send command
Return
C1:OFST -5.00E-01V
Get the current voltage position values: voffset = -0.5V.
According to the wave data, we can know the first point of waveform is
the 22th data "02", convert to decimal is "2" (Hexadecimal converted to
decimal).
The first point of wave data voltage value = 2*(0.5/25)-(-0.5) = 0.54V.
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:
C1:VDIV?
.
C1:OFST?
