Range Override - Keysight Technologies N7700 User Manual

Keysight N7700 Photonic Application Suite, Fast Spectral Loss Engine, User's Guide
Parameter
Initial Range (dBm) (Measurement Setting):
Dynamic Range Scans:
Fast Spectral Loss Measurement Application
Description
Sets the power range of the measurement. The
value defines the maximum allowed power.
Power values that exceed this value by more
than 3dB will result in clipped results. In case
of low power at the power meter (e.g. DUTs
with significant loss) the Initial Range should
be reduced to utilize maximum dynamic range.
By default all ports will use this range. See

Range Override

how to use different ranges for different power
meter ports.
If Auto check-box is set, the measurement
engine will choose the appropriate power
range for the measurement automatically. The
range will be adjusted individually for each
port. The most sensitive range will be chosen
for which no clipping will occur.
For measuring devices with very high dynamic
ranges, the engine can combine results
obtained from measurements performed at
different power range settings (stitching).
Dynamic Range Scans defines the number of
measurements to be combined this way. Use
the Decrement setting to define the step by
which the power meter range setting will be
changed in each dynamic range scan.
By default, all ports will use this setting. See
Range Override
on how to use different settings for different
power meter ports.
