Product Q&A
Q:What should I check if the output power of the power amplifier is lower than expected during testing?
A:
It is recommended to troubleshoot step by step as follows, prioritizing the elimination of non-hardware failure factors: a. Check the input signal: Verify whether the input signal to the power amplifier meets the standard requirements. A weak input signal is a common cause of low output power. b. Verify software settings: Check if the ALC (Automatic Level Control) function of the power amplifier has been set to a low output power level via software. Adjust it to appropriate parameters and retest
Q:What are the possible causes if the power amplifier gain fails to meet expectations, and how to solve them?
A:
The core troubleshooting directions for low gain of the power amplifier include software settings, system loss, and hardware failures. The specific solutions are as follows: a. Adjust software attenuation parameters: First, check the power amplifier control software to confirm whether the ATT (Attenuator) attenuation function is enabled. If so, reduce the attenuation or disable the function as needed. b. Calibrate the test system: Perform systematic calibration on the cables, connectors, passive
Q:How to accurately locate the problem if the software or instrument shows a high VSWR (Voltage Standing Wave Ratio) of the power amplifier?
A:
Abnormal VSWR is mostly related to link matching, and troubleshooting should be carried out step by step according to different test scenarios: a. Abnormal VSWR detected by software: In most cases, it is caused by excessive VSWR of components connected to the rear of the power amplifier, such as cables, connectors, and passive components. Replace the rear-end components one by one and retest to locate the faulty component. b. Abnormal VSWR detected by instrument: It is necessary to first calibra
