stormdogMy friend Erik drove an hour from his place to rescue me by getting me out to buy a battery! Thank you so much! *hugs* We got to hang out and be social for a while too. It was nice to catch up after a while.
After he left I went back to my workbench.
My function generator and frequency counter work! *bounces* Well, the square wave on the generator doesn't seem to work, but no biggie. The frequency labels on the generator bear only a loose relationship to reality, but I can check the frequency on my scope and compare/confirm with my counter.
Generator Range | measured frequencies
1-10hz | .8 - 18
10-100hz | .6 - 192
100-3khz | 156 - 4.1k
3k-65khz | 333 - 7.1k
65k-1mhz | 58.8k - 740k
And my frequency counter seems to read "0" above about 99khz even though it's supposed to be good to 75mhz. For test equipment that cost me less than $15 a pop, I can live with that for now.
