5.2.4 Setting Output Waveform
The PPG
Data
connector and
Data
connector are AC coupling.
When it is necessary to impose DC voltage on an output waveform,
connect a bias-T.
CAUTION

The impedance of the Data Out and Data Out
connectors is 50 Ω. Measurement may not be
performed correctly if a coaxial cable with another
impedance is used or if the impedance of the DUT is not
50 Ω.

The amplitude of signal output to the Data Out and
Data Out connectors is 0.1 to 0.8 Vp-p. Check that the
output voltage amplitude does not exceed the DUT
maximum input specifications. If it does, connect an
attenuator to the output connector.
Set the bit rate and amplitude of the waveform output to the
Data
and
Data
connectors.
