Return Loss Measurement
7
Equipment required
Return Loss and Insertion Loss can be measured in several ways. The
method used by the 8161x series Return Loss modules requires the
following equipment:
• A Keysight 81610A Return Loss module (where an internal source is not
present), or a 81611A, 81612A or 81613A Return Loss module (where
an internal source is present).
• If the Return Loss module does not include an internal source, or you
choose to use an external source, a Laser Source module.
• A Power Meter.
A typical setup, using a Keysight 81610A Return Loss module, where the
DUT is a connector pair, is described in
Figure 98
Measuring Return Loss and Insertion Loss
To measure insertion loss you measure the power transmitted through the
DUT, see
NOTE
If you are using an 81534A Return Loss Module, it is important that the
Laser Source has a stable output. 8161x Return Loss modules include a
monitor diode to compensate for power variation in the Laser Source.
