Appendix F: Detector Calibration - SARK 110 User Manual

Appendix F:
This procedure performs alignment of the SARK-110's internal measurement circuits. This
operation is done once at the factory and it is not necessary for the user to repeat it, but the
procedure is detailed for completeness. This procedure comprises a calibration phase and an
optional detector-test phase to check the detector circuits.
For Detector calibration, the Short load is connected directly at the Test port; see the figure
below. For the optional detector test phase, the following loads are required: 50, 100, and 200-
ohm.
Before performing this operation it is strongly recommended that the file containing the factory
results, detcalib.dat, is backed up to enable a restore, if needed.
Select «Setup» «Calibration» «Detector Calibration» to start the detector calibration procedure.
