How to Increase Your Signal Analyzer's Dynamic Range to See Low Level Signals - What the RF (S01E04)

Ready for the 1 hour deep dive into RBW vs noise vs sweep speed!

[@RobeenaShepherd]

One day I'll have a spectrum analyser! I need to have a genuine use for one first though... and then a lot of money I don't need... :)

[@calholli]

That took a lot of words just to say: 'hey, turn down the knob" :) ... This is why I'd rather learn by watching hands on with some live action. I learn so much faster on the fly

When did the next scope months will come? eagerly waiting...

[@jafinch78]

Fun with WTrF is in the noise floor? Thanks man!

[@karthikgp4849]

can you explain about video bandwidth VBW

[@KeysightLabs]

The spectrum analyzer Wikipedia page actually has the most succinct answer I can find: "The video bandwidth filter or VBW filter is the low-pass filter directly after the envelope detector. It's the bandwidth of the signal chain after the detector. Averaging or peak detection then refers to how the digital storage portion of the device records samples-it takes several samples per time step and stores only one sample, either the average of the samples or the highest one. The video bandwidth determines the capability to discriminate between two different power levels. This is because a narrower VBW will remove noise in the detector output. This filter is used to “smooth” the display by removing noise from the envelope. Similar to the RBW, the VBW affects the sweep time of the display if the VBW is less than the RBW."
