8.3. Calibration Notice
SeeGull HB flex scanning receiver is
calibrated at the factory. The calibration
data is stored in the internal non-volatile
memory in 1 dB steps for the whole input
signal dynamic range. Recalibration is
recommended every 2 years in order to
maintain the specified accuracy levels. Re-
calibration is available as an optional
service from PCTEL.
The SeeGull HB flex scanning receiver is
calibrated for several sources of variations
including amplitude levels, ambient
temperature, input frequency, and internal
noise levels for narrow and wide channel
bandwidths. The calibration parameters are
stored as single values or arrays in the
scanning receiver
s’ non-volatile memory.
Automated test and calibration stations use
proprietary software which performs the
process with no or minimum human
intervention. The calibration process is
followed by a fully automated production
test. The test results are stored in a central
quality database and they are extracted and
used for periodic quality audits.
Every unit that passes the calibration and
test process successfully receives a
Certificate of Calibration. This Certificate is
shipped back with the unit.
The complexity of the calibration process
precludes field calibration. It is highly
recommended that
PCTEL’s scanning
receivers be returned to the factory annually
to maintain the units’ exceptional
measurement capability.
