- Display of UHF measurement result
s (406.028 MHz for ADT406 ELT, 406.025 MHz for A06,
A06V2 and S06)
The test bench measures the following UHF data:
 UHF power expressed in dBm,
 frequency deviation (DFo = F ELT – (406.028 MHz for ADT406 ELT, 406.025 MHz for A06
, A06V2 and S06) expressed in kHz,
 UHF transmission recurrence time (Tr) expressed in seconds,
 pure carrier pulse duration (Cpp) expressed in milliseconds,
 UHF transmission time (Ce) expressed in milliseconds,
 message digital pulse rate (H400) expressed in Hz,
 positive (Phi1), negative (Phi2) and total phase excursions (PhiTot) expressed in radian,
 the ELT message is summarized in the "ELT Identifier" box.
- Display of the VHF measurement results (121.5 MHz)
The test bench measures the following VHF data :
 upward or downward amplitude modulation direction (Modulation LF),
 frequency deviation (DFo = F ELT - 121.5 MHz) expressed in kHz,
 amplitude modulation frequency sweep repetition rate (Fsweep) expressed in Hz,
 amplitude modulation minimum frequency (Fmin) expressed in Hz,
 amplitude modulation range frequency (Frange) expressed in Hz,
 amplitude modulation maximum frequency (Fmax) expressed in Hz,
 peak power of the 121.5 MHz transmitter (Pvhf) expressed in dBm.
- Display of the UHF measurement results (243 MHz)
The test bench measures the following VHF data:
 upward or downward amplitude modulation direction (Modulation LF),
 frequency deviation (DFo= F ELT - 243 MHz) expressed in kHz,
 amplitude modulation frequency sweep repetition rate (Fsweep) expressed in Hz,
 amplitude modulation minimum frequency (Fmin) expressed in Hz,
 amplitude modulation range frequency (Frange) expressed in Hz,
 amplitude modulation maximum frequency (Fmax) expressed in Hz,
 peak power of the 243 MHz transmitter (Pv
hf) expressed in dBm.
