USB2PMB1# Adapter Board
Evaluates: Munich (USB2PMB1#)
e) Plot in Windows: This generates three other
windows in additions to the scope viewer in the
GUI (Figure 11). The three windows apart from the
regular scope viewer include:
i) ADC Code of the current reading
ii) FFT measurement
iii) Histogram Measurement
f) Save plot to File: Saves the current plots to file.
g) Calibrate: If the user wishes to calibrate, this option
enables a real time calibration. From Figure 12,
there are two steps for complete calibration.
i) Save Settings to File: Saves the current set-
tings for measurement.
ii) Read Settings from File: Reads the last set-
tings that are in the file. If one wishes to reset to
factory default, then the appropriate .ini file has
to be deleted.
iii) Shunt Resistor value: This option allows
entering the exact value of shunt resistance in
Cupertino board. This also allows the user to
change the resistance and scale the current
measured.
iv) Offset: The offset calibration is done by forcing
a 0V input voltage or 0mA current to obtain the
plot counts. This plot counts value if other than
0, should be fed in the offset digit tab.
v) Volt per Code: This option calibrates for gain
error. The volt per code calibration is done by
forcing approximately 80% of the specified
input range (4.096V) at the input to obtain the
code.
