Hello dear members;
I would be very appreciated if someone answer my question below, which is probably is easy for experienced users.
I have an Aaronia HF Spectran spectrum analyser and it is not a real time spect.analyser. **broken link removed**
am I understand right about the principle of working ?
1-) some signal comes to its input and it reads this signal for example during 5 ms or whatever the sampling time is.
2-) it keeps the sigal in its memory, and calculate frequency domain values by usig heterodyne principle.
3-) while this calculation keeps going on (because the needed frequency band is wide), it doesn't read new inputs.
4-) when it finishes to calculate, it reads new signal from its input.
So ı can loose some values because of the 3.rd above.
or is it going this way ?
1-) the same as above
2-) it calculates the first frequency value of the needed band by using the signal sample
3-) while it calculate this , it can not read new signals from its input.
4-) when it finds the first frequency value, it reads again from its input and begin to calculate second frequency value.
