Verification Kit for use with AT-500 Antenna Tester © Copyright 2007 by Bird Electronic Corporation Verification Kit Part Number 7000A546 Instruction Book Only Part Number 920-7000A545 Rev A
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: ρ = ( VSWR-1 ) ⁄ ( 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.
Bird Technologies Instructions 1. Connect the adapter to the test port on the Antenna Tester. 2. Connect the mismatch to the adapter. 3. Press the ON key. 4. Press the MENU key. 5. Press the MEAS MATCH key. 6. Press the SINGLE FREQ key. 7. Press the UNITS key. 8. Press the RHO key. 9. Press the FREQ MHz key. 10. Using the numeric keys, enter the frequency for the first data point as documented in the test data for the mis-match. 11. Press the ENTER key. 12.
Calibration For maximum performance and accuracy, the Antenna Tester should be calibrated once every 12 months or if the verification test indicates the accuracy is not within the specified range. Return the unit to the Bird Electronic authorized service center listed below. Service Center U.S.A.
