I have two max038 lying around which wait only for me making a
schematic
for a generator. these are sine/triangle/square wave generators that work up to 20Mhz. there is a cheaper version that works to 1Mhz which is sufficient for what you need.
Is this the same sort of part as the Intersil (?) 8038? I built a generator around one of those some years back, it was fairly simple, and it's very flexible.
It's similar but not the same. The intersil part is only 300kHz max.
I toyed with a design not too long ago that would have generated a logarithmic sweep voltage and swept the MAX038 while applying horizontal drive to an oscilloscope, and thereby produce 2-D frequency response graphs. I don't know if that is practical or not, but it sounded cool.
