Info on getting wave data please.

Here we will discuss many topics on electronic designs and circuits for various functions. PIC Chip programming has enormous potential in so many applications, that will be included in this forum as well.

Info on getting wave data please.

As i can't afford a 'scope at the moment i'm using a dmm with a data logger programme to try and get some info on khz and duty cycle,problem is i get a few readings then nothing unless i move one of the probes away then back. I'm taking them directly from the plate contacts with everything switched on--i get the most consistant results if i hold one probe a little bit away from making contact. I've tried on 3 pwm circuits with the same problem--any help or guidance would be appreciated,thanks,Dave.

thanks chemelec,sorry i haven't been here to reply earlier but all sorted now,so i can continue.I'm presently experimenting with a multivibrator set up and getting good square waves at close to 50% duty at output pin and double the frequency at the oscillator pin when running in astable mode--just bringing the the frequency down to a more suitable level at the moment(output pin gives 46kHz x 2 at osc. pin).
Completely starting afresh with everything and enjoying the learning again,regards,Dave.
