Introduction
ρ VSWR-1()VSWR+1()⁄=
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:
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-500 Antenna Tester. These instructions were written with
the understanding that the operator is familiar with the operation of the Antenna
Tester. Refer to the Antenna Tester Operator Manual for more information.
