Performance
Test Record
Table 2-1 is a form you can copy and use to record performance verification
test results for the matrix module. Information concerning test limits,
measurement uncertainty, and test accuracy ratio (TAR) is provided below.
Test Limits Test limits are defined for Closed Channel Resistance Test and DC Isolation
Test using the specifications in Appendix A of the Agilent E1465A/E1466A/
E1467A Relay Matrix Switch Modules User’s Manual. The specifications
are single-sided, (i.e., there is an upper limit or a lower limit, but not both).
In the Performance Test Record, the Minimum or Maximum column will be
blank.
