1、 Avoid operating beyond rated parameters

1. Voltage and current overload
   • It is strictly prohibited to input voltage exceeding the nominal value of the device (such as ± 5% fluctuation range), otherwise it may break through the internal circuit or damage the power module.
   • Avoid exceeding the rated output current (such as peak current limit), as long-term overload can cause component heating, performance degradation, or even burnout.
2. Frequency and pulse width exceed the limit
   • Do not set the pulse frequency or pulse width beyond the technical specifications of the device (such as a maximum frequency of 100MHz and a minimum pulse width of 1ns), otherwise it may cause signal distortion or trigger protection mechanisms.
   • When dynamically adjusting parameters, it is necessary to gradually change them to avoid circuit impact caused by instantaneous jumps.
3. Temperature and humidity exceed the standard
   • Avoid long-term use in environments with temperature>40 ℃ or humidity>85%, as it may accelerate component aging or cause short circuits.
   • Do not expose the device to direct sunlight, high temperature heat sources, or humid environments (such as water or condensation).

2、 Avoid mechanical damage and physical impact

1. Vibration and Drop
   • When transporting or moving equipment, special packaging boxes should be used to avoid internal components becoming loose or welding points falling off due to severe vibrations or drops.
   • It should be fixed on a stable platform during installation to prevent displacement or contact caused by vibration during operation.
2. Improper interface plugging and unplugging
   • It is strictly prohibited to plug or unplug signal lines, power lines, or coaxial cables while the equipment is powered on, otherwise it may cause arcing damage to the interface or trigger a short circuit.
   • When plugging or unplugging, align with the direction of the interface to avoid excessive force that may cause bent pins or damage to the casing.
3. Cleaning method incorrect
   • It is prohibited to use corrosive solvents such as alcohol and gasoline to wipe the equipment casing or interface. A dry soft cloth or specialized electronic cleaner should be used instead.
   • Avoid using sharp tools (such as screwdrivers) to clean the interior of the heat dissipation holes or interfaces to prevent scratches or residual metal debris.

3、 Avoid electromagnetic interference and signal pollution

1. Strong electromagnetic field environment
   • Stay away from strong electromagnetic interference sources such as high-power motors, transformers, and radio transmitters, otherwise it may cause signal noise or control abnormalities.
   • If necessary, use shielded cables or magnetic ring filters to reduce interference.
2. poor grounding
   • Ensure reliable connection of the equipment grounding terminal to avoid component breakdown or personal injury caused by static electricity accumulation or leakage.
   • When multiple devices share grounding, it is necessary to check the grounding resistance (usually<4 Ω) to prevent interference from ground current circulation.
3. Signal circuit open circuit
   • Long term operation is prohibited when the output terminal is not connected to a load, otherwise the power amplifier or output transformer may be damaged due to reflected waves.
   • The load impedance needs to match the output impedance of the device (such as 50 Ω) to avoid impedance mismatch causing signal attenuation or reflection.

4、 Avoiding software and configuration errors

1. Firmware upgrade risk
   • Before upgrading firmware, it is necessary to back up the original program to avoid device bricking caused by upgrade interruption.
2. Parameter configuration conflict
   • When modifying multiple parameters (such as frequency, pulse width, phase) simultaneously, step-by-step operation is required to avoid parameter combinations exceeding the device's capability range.
   • Before saving the configuration file, it is necessary to verify the validity of the parameters to prevent incorrect settings from causing the device to fail to start.
3. Remote control vulnerability
   • When enabling network functions, it is necessary to set a strong password and update it regularly to avoid unauthorized access or malicious attacks.
   • Prohibit opening device management ports in public network environments to prevent data leakage or control theft.

5、 Avoid maintenance and neglect of upkeep

1. Blockage of cooling system
   • Regularly clean the dust on the cooling fan and fins to avoid overheating protection or component damage caused by poor ventilation.
   • Do not block the air inlet or outlet of the equipment to ensure smooth air circulation.
2. Risk of battery aging
   • If the device has a built-in battery (such as a lithium battery), it is necessary to avoid overcharging, overdischarging, or long-term idle, otherwise it may cause swelling, leakage, or even explosion.
   • When not in use for a long time, the battery level should be maintained at 40% -60% and charged every 3 months.
3. Delay in calibration cycle
   • Regularly calibrate according to the instructions (such as once a year) to ensure that the accuracy of parameters such as pulse amplitude and frequency meets the standards.
   • Calibration requires the use of specialized instruments such as oscilloscopes and frequency meters to avoid the accumulation of errors caused by the use of non measuring equipment.
