4G & 5G interference hunting with a real time spectrum analyser

The term real time spectrum analyser (RTSA) is commonly used but what does it really mean? Understanding the differences between traditional analogue spectrum analysers and real time devices is a great way of getting to the advantages of using a RTSA for interference hunting.

What makes a RTSA better?

Most of us in the RF & microwave world are familiar with spectrum analysers but what’s the difference between a real time spectrum analyser (RTSA) and a more traditional swept-tuned instrument? The clue is in the name and a swept-tuned analyser sweeps from left to right displaying measurement results sequentially i.e. not real time.

Menlo Micro MM3100

So how does a micro electromechanical switch have such good power handling capabilities? The answer is that Menlo use the same cell design and by combining many cells in series or paralell the voltage or current handling capability can be scaled up as required, it's scalable from mW to kW.

4G/LTE TV interference; serious problem or not?

Well the answer to the question is despite a number of trials we’re still not sure. It’s tough to get to the truth of the matter because trials to date have had some issues like base stations not operating on full power or maybe the TV channels for the given area aren’t the most likely to be affected.

Solving the 4G LTE interference problem

It was excellent earlier in the year when we won a large contract from DMSL (an organisation funded by and representing the 4G operators) to supply filters for use by both individual consumers and ‘communal’ units designed for use in premises with a shared aerial e.g. blocks of flats.
