Bird AT-400 Antenna Tester

ROM, EEPROM, RAM, A/D, TEMPR, PLL Test Fails

Ensure the results are valid by repeating the self test or turning the unit off then back on. If the problem persists return the unit for service.

Stuck Keys Test Fails

If any characters other than 0 are displayed next to stuck keys during power up test, perform the keypad test on page 36 of this section. Remember, if a key is depressed during power up to display the power up test results it is normal for other characters to be displayed. If the key remains stuck return the unit for service.

“Noise” is Displayed During Testing

The Antenna Tester measures background noise to determine if nearby signals could cause an erroneous match measurement. Power down all nearby transmitting antennas. All interfering signals must be removed before resuming measurement.

Antenna Tester indicates a Perfect Match

When measuring the match of an antenna in a high RF environment, the Antenna Tester indicates a perfect match (i.e. VSWR = 1.00, Return Loss = -32 dB, or Match Efficiency

=100%). This is caused by the coupling of interfering signals into the Antenna-Under-Test. If sufficiently strong, the interfering signals can over-power the measurement signal inside the Antenna Tester. Normally, this results in degraded measurement accuracy. Bird Antenna Testers minimize this effect by measuring the interfering signal during the time between match measurements. The inter- ferer magnitude is subtracted from the magnitude of the measurement signal. For relatively small interferers (i.e. interfering signal smaller than the measurement signal), this technique yields approximately 10 dB better rejection. If the interfering signal becomes larger than the measurement signal, the correction output approaches zero, corresponding
