5. Perform any measurement with the setup that contains the calibrated component.
The measurement results do not include the effects from the component.
How to Compensate for Additional Gain or Attenuation after Calibration
If a gain or an attenuation is inserted in the measurement after calibration, this effect
can be reflected in the display of the normalized trace on the R&S
FPL1000. Thus, the
measured trace and the normalized trace are not so far apart in the display, so that you
can zoom into the normalized trace without cropping the measurement trace.
Prerequisite: a calibration has been performed for the original measurement setup,
except for the component causing an additional gain or attenuation (as described in
"How to Calibrate a Measurement Setup Using a Tracking Generator"
1. Insert the additional component in the calibrated measurement setup and perform
a new measurement.
2. Select the "GEN Config" tool on the toolbar.
3. With active normalization, set the "Calibration Reference":"Value" to the same
value as the gain or attenuation the inserted component causes.
4. Optionally, shift the reference line further down in the result display by decreasing
the "Calibration Reference": "Position".
The normalized reference trace moves to the position of the measured trace.
5. Optionally, zoom into the measured trace by changing the y-axis scaling (or the
range: "AMPT > Scale Config > Range").
The measured trace is still fully visible, and the absolute values are still valid.

The R&S
FPL1000 can provide signals to different output connectors.
These connectors are only available if the R&S
FPL1-B5 option is installed.
For details on connectors, refer to the R&S
FPL1000 Getting Started manual, "Front /
Rear Panel View" chapters.
