BERTWave
Coaxial Cable
Use 3-pin power cords.
AC Outlets
Be sure to connect the ground structure
(like frame ground) and the ground
terminal with a ground wire.
DUT
DUT: Device Under Test
Connect to a common ground.
Connect a protective attenuator, within the
range not affecting results of measurement.
(Recommended bandwidth: 25 GHz or more)
Figure 2.15.1-1 Example of Connection with DUT
Follow the procedure below to check for electrical overstress to the
BERTWave before connecting DUT (Device Under Test).
Checking the ground connection using a tester
1. Connect DUT and the ground terminal of the BERTWave with a
ground wire.
2. Turn on the power to DUT and BERTWave without connecting DUT
to the I/O terminal of BERTWave.
3. Measure the voltage between DUT’s ground structure and ground
terminal of BERTWave with a tester in AC mode, and confirm the
voltage is 0 V.
If the voltage measured in step 3 is not 0 V, there is a possibility that
BERTWave and DUT may not be connected to a common ground. In this
condition, do not connect the I/O terminal of BERTWave and DUT.
Failure to do so may cause damage to BERTWave due to a voltage
exceeding a rated value.
Review the ground wiring by, for example, changing the location of the
DUT’s ground wire connected to BERTWave so that the voltage
measured in step 3 to be 0 V.
