Q2. Conversion of watt and power Antenna working What is pim testing
Ans. 
Conversion of watt and power, antenna working, and PIM testing are common topics in the field of test engineering.
• Watt is a unit of power, commonly used to measure the rate of energy transfer.

• Power is the rate at which work is done or energy is transferred.

• Antenna working involves understanding how antennas transmit and receive electromagnetic signals.

• PIM testing (Passive Intermodulation Testing) is a method used to de...read more

Q1. What is return loss?
Ans. 
Return loss measures the amount of signal reflected back in a transmission line, indicating signal integrity.
• Return loss is expressed in decibels (dB).

• A higher return loss indicates better signal integrity.

• For example, a return loss of 20 dB means that only 1% of the signal is reflected back.

• It is crucial in RF and telecommunications to ensure minimal signal loss.

• Return loss can be affected by impedance mismatches in t

Q2. What use of network analyser & signal generator?
Ans. 
Network analyzers and signal generators are essential tools for testing and analyzing electronic signals and network performance.
• Network analyzers measure the network parameters of electrical networks, such as S-parameters.

• Signal generators produce electronic signals with specific frequencies and amplitudes for testing purposes.

• In RF testing, a network analyzer can help identify impedance mismatches in antennas.

• Signal ...read more
