Well the frequency shift with the TG (as a function of the RBW/sweeptime) seems to have been fixed with the .15 firmware.
However I
still have the amplitude jump just below 500 KHz (also see my previous postings)
With all settings default and the RBW set at 10 KHz (span from 300-700 KHz) the jump is very present:
RBW reduced to 1 KHz.
No frequency shift (fixed, good!) but the amp jump at 10 KHz RBWE.. not so good.
Did they only look at & fix the 10 MHz issue? Funny thing is my 815 never had the 10 MHz amp jump issue.
