Spectrum Analyzer Basics: RBW, Noise Floor, and Buying Used Equipment
Why RBW and noise floor define analyzer usefulness
When buying a spectrum analyzer, especially used — two specs matter more than most:
Resolution Bandwidth (RBW)
Noise floor
These determine whether you can:
resolve closely spaced signals
detect weak emissions
perform meaningful RF analysis
Understanding these specs prevents expensive mistakes.
Resolution Bandwidth (R… Read more

Linear vs Switching Power Supplies: Choosing the Right DC Supply for Sensitive RF Applications
Why power supply selection matters in RF and semiconductor labs
Power supplies aren’t just utilities — they directly affect:
noise floor
measurement accuracy
device stability
In RF and semiconductor environments, choosing between linear and switching supplies can make the difference between:
clean data
misleading results
Linear power su… Read more
Analog vs Digital Oscilloscopes: Why Some Engineers Still Prefer Tektronix Analog Scopes
Why this debate still matters in electronics labs
In semiconductor labs and RF development environments, oscilloscopes aren’t just debugging tools, they’re signal truth machines. While digital storage oscilloscopes (DSOs) dominate modern labs, many engineers still keep a Tektronix analog scope on the bench.
Why? Because analog scopes offer someth… Read more
