USB2PMB1# Adapter Board
Evaluates: Munich (USB2PMB1#)
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 Configuration Options
i)
ADC Count:
This option plots the ADC
code itself on the Y-axis with the number of
samples on the X-axis.
ii)
Voltage:
This option plots the converted
voltage value.
iii)
0 to 10V to Temp:
Plots the temperature
measured from IFM TA3231 Temp-Sensor.
This sensor sinks/sources current propor-
tional to the temperature measured. The
shunt current and the temperature mea-
sured would also be indicated at the bottom
of the GUI.
iv)
FFT:
This option plots the FFT measure-
ment on the Y-axis vs. frequency on the
X-axis.
v)
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.
vi)
History
i)
History Length:
This option allows the
user to view the history data by choosing
the history 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.
vii)
Calibrate:
If the user wishes to calibrate,
this option enables a real-time calibration.
i)
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.
ii)
Volt per LSB:
This option calibrates
for gain error. The volt per code cali-
bration is done by forcing approxi-
mately 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
(

Display Section
1)
Reading Section
a)
Read Once:
This pushbutton tab allows dis-
crete 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.
2)
Display Section
a)
Result:
This displays the HEX value of the
generated serial Data (B0:B15)
b)
B0 to B15:
This displays the individual Bit of
serially generated Data
i) B0: RES: Reserved.
ii) B1: OT: Display status of internal tempera-
ture monitor.
iii) B2: UV: Display status of field supply volt-
age.
iv) B3 to B7: CRC: Internally calculated and
generated cyclic redundancy check code.
v) B8 to B15: Serially generated data bits.
c) IN1 to IN8: Displays the input data applied.
