Iridium Test Coverage and Supported Test Cases

The Averna Iridium PLTS supports the following test cases with in-band and wide-band options.* See also Supported Iridium Production Tests below.

Test Case	Description	In-Band	Wide Band
BER	% BER at a variable input level (dBm)	✓	✓
BER 2% Sensitivity	Determines input level (dBm) required for 2% BER	✓	✓
BER with Interference	BER with alternate and adjacent interference		✓
Receiver Blocking	Receiver spurious rejection and blocking		✓
RSSI	Returns UUT RSSI per input level (dBm)	✓	✓
FER	Determines % FER based upon frames with failed synchronization to downlink	✓	✓
Modulation Accuracy (EVM)	Measures peak and RMS EVM between 0.5 and 10%	✓	✓
Tx Power	Tx power in dBm	✓	✓
Burst Ramp Time	Measurements for ramp time and fall time in uS	✓	✓
ACCP	Measures adjacent channel power in adjacent and alternate channels over specified bandwidth (43.33 kHz)	✓	✓
Narrow Band Spectral Mask	Applies narrowband spectral mask measurements for Iridium transceivers within 1 MHz of desired channel	✓	✓
PRE-COMPLIANCE Wideband Spurious Emissions	Measures emissions up to 3 GHz and applies appropriate regulatory limits		✓

* Based on 20 MHz band centered at 1621 MHz, 41.6667 KHz channel bandwidth, and 8.28mS Tx burst in 90 mS frame.
