Introduction
Connecting a mismatch of a known value and measuring it with the Antenna Tester provides a test to determine the degree of measurement accuracy.
Measurement accuracy is specified to be ± 0.040 of Rho (p), where:
VSWR 1–
ρ
-------------------------=
VSWR 1+
Because of the manufacturing tolerance, each mismatch is analyzed across the
frequency band of the Antenna Tester. Rho data is recorded so that future comparisons can be made without regard to the manufacturing tolerance.
This verification kit is used to verify Antenna Tester performance. It is intended
for use with the AT-800 Antenna Tester. These instructions were written with the
understanding that the operator is familiarwith the operation of the Antenna Tester. Refer to the Antenna Tester Operator Manualfor more information.
