2.15 Precautions for Preventing Damage
Before connecting signals to the input and output connectors of the
BERTWave, always check that the signals are within the specified
voltage range.
If an out-of-range signal is input, the BERTWave may be damaged.
CAUTION

Use a 50

/GND terminator for the device to be
connected to the output connector.

Never open the case of the BERTWave.
If you open it and BERTWave has failed or sufficient
performance cannot be obtained, Anritsu may not
accept a request for repair.
2.15.1 Precautions on Electrostatic Discharge and Electrical
Overstress
CAUTION

When signals are input to the BERTWave, avoid
excessive voltage beyond the rating. Otherwise, the
circuit may be damaged.

Never feed any current or input signals to the output
connector.

As a countermeasure against static electricity, connect
the ground structures (for example, frame ground) of
external devices, including experimental circuits, to the
ground terminal of the BERTWave by using ground
wires before connecting the IO connector.
Shorten ground wires as much as possible.

To the input terminal of the BERTWave, connect an
attenuator that can protect the BERTWave without
affecting measurement results. An attenuator with a
bandwidth of 25 GHz or more is recommended.
