Other Mandatory Test Items:
1. When the downlink is in normal operation, the downlink operation indicator light shall stay on continuously.
2. When the downlink outputs full power, with the uplink threshold set to -92, the uplink indicator light shall not turn on.
3. The main/standby switch should be able to switch normally.
1. Overpower Alarm
An alarm is triggered when the actual output power of the power amplifier module exceeds the rated power by 2dB; the alarm threshold can be set via software with a dynamic range of 20-
40dBm and a step size of 1dB.
2. Over-temperature Alarm
An alarm is triggered when the internal temperature of the module exceeds +85℃; the power amplifier output is turned off when the temperature exceeds +90℃; the power amplifier
resumes operation after the temperature drops below +65℃ . The alarm thresholds can be set via software with the following ranges: alarm temperature 20-85℃; shutdown temperature 25- 90℃ (must be at least 5℃ higher than the alarm temperature); recovery temperature 0-75℃
(must be at least 5℃ lower than the alarm temperature); with a step size of 1℃ .
3. VSWR Alarm
a. The test is valid when the output power is greater than 20dBm;
b. An alarm is triggered when the reflection at the power amplifier output port is excessive and the VSWR exceeds 3:1;
c. When connected to a 1.5 VSWR load, the displayed VSWR value should range from 1.3 to 1.7;
d. When connected to a 2.0 VSWR load, the displayed VSWR value should range from 1.5 to 2.5;
e. When connected to a 3.0 VSWR load, the displayed VSWR value should range from 2.0 to 4.0;
4. RF Switch
When set to "On", the squelch switch is active; when set to "Off", the LNA cannot be turned on even if the input signal is greater than the squelch threshold.
5. Power Amplifier Fault Alarm
This alarm is triggered when: the power amplifier output is below 20dBm (with squelch
threshold enabled, no alarm if disabled), or the output power (dBm) ≠ input power + gain - attenuation, or any other alarm among VSWR alarm, over-temperature alarm, and overpower alarm occurs.
6. LNA Fault Alarm
This alarm is triggered when the LNA output is below -35dBm (with squelch threshold enabled, no alarm if disabled), or the output power (dBm) ≠ input power + gain - attenuation.
7. Same-frequency Priority
Downlink priority: When the module is in same-frequency mode (or same/different frequency mode), the uplink channel is turned off when there is a downlink signal output.
8. Master-Slave Switching
a. There are two power amplifier modules inside the module, one as the main module and the other as the standby module;
b. When a fault occurs in the main power amplifier module (including LNA fault alarm), it automatically switches to the standby module and triggers an alarm;
c. The fault identification of the power amplifier module is only performed when the output power is greater than 20dBm;
d. A trigger button is set in the program to verify the master-slave switching function of the module;
e. When the switch button is pressed, the module will force switch to the standby amplifier module and trigger an alarm;
f. Normal state can only be restored after re-powering.
9. Operating Mode Setting Function
The module's same-frequency/different-frequency/same/different frequency operating modes can be set, and the settings should be retained after the module is powered off.
10. VSWR Protection Function
Protection measures are taken at the input port of the uplink LNA to ensure that the uplink is not damaged when the power amplifier is open-circuited; a protection function is added at the
output port of the power amplifier to ensure that the power amplifier chip is not damaged when open-circuited.
11. Requirements for Saving Detection Results
When the module is in working state (squelch threshold enabled, module in amplification state), the module shall detect the state of the amplification path, determine faults, store the results in the module for subsequent query, and report the stored results when the main control unit
performs a query (i.e., retain the parameters and state of the last call, with uplink and downlink saved separately: save uplink parameters and state during uplink calls, while downlink
parameters and state remain unchanged; save downlink parameters and state during downlink calls, while uplink parameters remain unchanged).
Only the latest query result of the self-test s hall be saved.
12. Reserved Gain Temperature Compensation
A 5dB reserve is set for gain compensation under high and low temperature conditions, with adjustable steps of 0.5dB.
