USB2PMB1# Adapter Board
Evaluates: Munich (USB2PMB1#)
8) Real Time Scope: The scope present on the left
side of the GUI represents the measured data with
number of samples in x-axis and y-axis is selected
from the available plot view options from the bot-
tom of the GUI environment.
a) Scope Options: On the top right corner of
the scope or the Histogram plot, plot settings
options are available for the user to play/pause,
zoom in/out, pan, print, save, and waveform
settings.
b)
Plot View Options
i) PlotCounts: This option plots the ADC
code itself on the Y-axis with the number of
samples on the x-axis.
ii) Plot Volts: This option plots the converted
voltage value.
iii) PlotCurrent: Plots the current measured
across the 200Ω shunt resistor present in
Campbell.
iv) PlotTemp: Plots the temperature measured
from IFM TA3231 Temp-Sensor. This sen-
sor sinks/sources current proportional to the
temperature measured. The shunt current
and the temperature measured would also
be indicated at the bottom of the GUI.
c) History
i) History Length: This option allows the user
to view the history data by choosing the his-
tory length for viewing the data.
ii) Show History of Average: Checking this
option allows the user to view entire data in
history up to the history length chosen.
d) Show Histogram: This pushbutton option
allows the user to view the resultant output in
Histogram. The X-axis is ADC code and the
Y-axis is the number occurrence.
e) Plots in Windows: This generates three other
windows in additions to the scope viewer in the
GUI. 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.
i) Save settings to file : Saves the current
settings for measurement
ii) Read settings from file: Reads the last
settings 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 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 (+10V) at input to
obtain the code.

Corona GUI Tab
This environment consists of the internal block diagram
of the Corona board and the remainder of the operations
to perform:
● Reading Section
● Display Section
1) Reading Section
a)
Read: This pushbutton tab allows discrete
sampling.
b) Read continuously: This feature allows con-
tinuous sampling. Once the Read continu-
ously button is clicked the button changes its
text to Stop Reading and the user would not be
able to disconnect the board from the software
until the user clicks the Stop Sampling button.
