8-channel inputs, making it relatively easy to increase the captured

channels for the current system.

The CN0549 is a single-channel IEPE-compliant, CbM develop-

ment platform geared toward software development.

GETTING STARTED

This section discusses the general procedure to set up the evalua-

tion test for the EVAL-CN0582-USBZ.

The setup requires the EVAL-CN0582-USBZ to be connected to a

Windows PC, with the CN0582 evaluation software installed; and

then to a vibration shaker, which acts as the stimulus for device

under test (DUT) measurements, as displayed in Figure 12.

Figure 12. EVAL-CN0582-USBZ System Test Setup

To test the basic functions of the board, follow these instructions:

1. Install the CN0582 Evaluation Software to the Host PC based

on the instructions listed in software installation guide.

2. After installing the software, connect the EVAL-CN0582-USBZ

board sensors to any of the analog inputs of using an SMA

cable; following these channel assignments:

a. CH0 for the Piezo reference sensor.

b. CH1 to CH3 for the DUT sensors (IEPE, MEMS, etc).

3. Connect USB Type-C cable to EVAL-CN0582-USBZ, and then

plug it in to the Host PC.

4. Open the software and for simple data capture, select DAQ

from the window options as shown in Figure 13.

5. Configure the software for the different settings required by the

sensor such as input signal coupling, offset, and gain. Enter the

recommended settings from Table 3 into the corresponding GUI

fields shown in Figure 14.

Level Shift Voltage

10500 to 13000 for each channel

Adjust accordingly depending on

the connected sensor per channel.

6. On the top right pane of the GUI, set the output parameters of

the signal generator following the input values suitable for the

vibration shaker as shown in Table 4.

Amplitude

500 mVp-p

Frequency

1000 Hz

7. Under the 'Channel Selector' field, switch on CH0 and CH1 to

display plots. Toggle the data capture 'Mode' button depending

on the preferred plot results.

8. Connect analog output of EVAL-CN0582-USBZ to the vibration

shaker using a BNC to BNC cable.

Note: Connect the analog output to the vibration shaker only

when the software has finished uploading the firmware to the

EVAL-CN0582-USBZ to prevent damage to the instrument.
