CALIBRATION TEST REPORT
(Notch Filter) Tektronix, Type 067-0938-00.
a. The purpose of the test report is to allow utilization of instruments whose values
have drifted outside manufacturer's specifications when referenced to nominal values, yet
with a drift rate sufficiently low to allow use within manufacturer's specified accuracy of
the previous test report value.
b. The performance specifications shall be ascertained by referencing present
measured values to previous measured values in lieu of nominal values.
If present
measured values are not within the tolerance guidelines of the initial and/or last test report
specification, the TI must be red-tagged. Calibration activities will maintain a case history
file of test reports for the TI.
2. The manufacturer states the nominal values as approximate and are to be used as
guidelines in preparing the initial test report ONLY. All succeeding calibrations must be
within .5 dB of previous test report. Maximum deviation allowed is 1.5 dB from initial test
report in four successive calibrations.
3. Under the conditions stated, the measured values are in error by no more than .3 dB.
This calibration is traceable to and compatible with National Institute of Standards and
Technology Measurements.
