Where can I adjust the RBW (Resolution Bandwidth)?
Hello,
Maybe I am blind, but, I was unable to find a way to set RBW. Can you help me with that?
RBW can be set, when using the V6 in "Sweep Mode" using the "Spectran V6 Sweep Zoom" block:
In realtime streaming you control the bandwidth using the IQ Power Spectrum block that controls the FFT size
You can switch the "FFT Size Mode" to "RBW" allowing adjustment via RBW (double click for numerical entry) instead of FFT size:
see https://v6-forum.aaronia.de/forum/topic/iq-power-spectrum/ for reference.
Within the factory mission "Sweep" you can set the RBW as needed but be aware that small RBWs will slow down the sweep (and dont make real sense in most cases anyway).
See https://v6-forum.aaronia.de/forum/topic/spectran-v6-sweeptime-vs-rbw/ and https://v6-forum.aaronia.de/forum/topic/spectran-eco-v6-sweep-time/ for sweep speed vs RBW setting depending on the SPECTRAN unit.
In addition you can switch the "Sweep" mission to real time mode "RBW":
This allows you to control the real-time mode by RBW instead of FFT size. In that mode you should in addition reduce the "Wrapped Spectrum" from default 4 wraps to a single wrap for a better graph usage:
