Table 2-3 is a form you can copy and use to record performance verification
test results for the RF Multiplexer modules. Information concerning test
limits, measurement uncertainty, and test accuracy ratio (TAR) is provided
below.
NOTE
The accuracy, measurement uncertainty, and TAR values shown in
Table 2-3 are valid ONLY for the specific test conditions, test equipment,
and assumption described. If you use test equipment and/or change the test
conditions, you will need to compute the specific values for your test setup.
Test limits are defined for closed-channel resistance test using the
specifications in Appendix A of this manual. The closed-channel resistance
test specifications are single-sided (i.e., there is an upper limit but no lower
limit). In the Performance Test Record, the Minimum column is blank.
For the performance verification tests in this manual, the measurement
uncertainties are based on 90-day accuracy specifications for the Agilent
3458A Digital Multimeter. The calculations are shown below.
Conditions:
•
4-wire ohms function, 10
•
90-day specifications
•
Worst-case reading = 2.0
M.U.
= 8.0x10
Test Accuracy Ratios are not defined for single-sided measurements, so all
closed-channel resistance measurements have 'NA' (Not Applicable) in the
(TAR)
TAR column.
