HI GUYS
I have a motorola signal generator that has 890-960 mh harmonics ;;;it says see conversion chart I have manual its not there any source or directions to get it
thankyou

I am going to guess that it is the old Measurements Sig Gen made for Motorola.
Each individual unit had a sheet with the signal strength value of the harmonics graphed out for that range.
It varied quite a lot from one unit to another.
A few to several dB.
You could make a new graph by checking it with a known service monitor, or spectrum analyser.
