USB2PMB2# Adapter Board

Evaluates: Munich (USB2PMB2#)

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.

Plot Configuration Options

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.

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

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.

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

(Figure 15) to perform:

● Reading Section

● Display Section

Reading Section

Read Once: This pushbutton tab allows dis-

crete sampling.

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.

Display Section

Result: This displays the HEX value of the

generated serial Data (B0:B15)

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.
