Before Use
Checking the output waveform with an oscilloscope
1. Connect the DUT and the oscilloscope using a cable with an
impedance of 50
Ω
.
2. Set the input impedance of the oscilloscope to 50
Ω
.
3. Observe the waveform with the oscilloscope, and perform the
following operations to check the observed waveform for surge
voltage exceeding the rated voltage*.
There is a risk of damage if a voltage exceeding the rated voltage* is
generated.
•
Turning On/Off the DUT power
•
Outputting a pulse from DUT
•
Connecting and disconnecting the cable between DUT and the
BERTWave
*: The rated voltages for MP2110A are shown in the table below.
