Hello,

I encounter the following issue for bandwidth (-3 dB) measurement.

If the X Scale is set to Log initially, the DDP will not show the bandwidth information as shown in the picture below.

I have to use linear for X Scale to see the bandwidth data.

: bandwidth available; pic2.png (94.94 KiB) Viewed 9079 times

Is it a bug or not?

Thank you.

It sounds like a display issue related to the initial Log scale setting—try switching to Linear scale first, then back to Log to refresh the bandwidth display.
