increase frequency of function generator

[bhuvaneshnick]

i have function generator and that is of range upto 3 mhz. Is there any possible way to get above 6mhz signal using my 3mhz function generator .Thank you in advance

You might be able to use a passive diode frequency doubler or perhaps construct an active frequency multiplier. The downside might be an increase in noise or other subtle artifacts in the output that might affect your measurement. I suppose it would really depend on how sensitive your intended application is. For any sort of critical measurement a better generator would be a wiser course of action

Psst! mHz is milli-Hertz (1e-3) amd Mhz is mega-Hertz (1e6). The rules say proper names get capitalized in units.

Do you need more than one frequency doubled?
Do you want a square-wave output?
Is a pulse output okay (square-wave having different on and off times)?
