Hi All.
I am trying to understand something here. What is the Tickle Frequency and how does that affect the output analogue voltage to the tube power supply.
For example.. If my laser is running at half power.. Will I see just a flat 2.5v signal… or will this signal be distorted somehow with a 20khz frequency embedded.
Many thanks for any explanations…
Dave
Tickle is only used for RF type machines, is yours a glass or metal tube machine?
When a tube turns off, this keeps it closer to it’s lase point, so you can get a faster response. Remember an RF machine, isn’t like an analog device (glass tube) at this level. I don’t have an RF machine, but from what I’ve read it’s useful for these types of metal tube lasers.
Oh.. thanks for the explanation.. so if I was to look at a waveform of the analogue input I would just see a clean trace with no spikes or distortion from the tickle…
If it’s on a glass-tube CO₂ machine, then the usual ZYE HV power supply applies a 250 Hz (-ish) low-pass filter to the input. It’s intended to demodulate PWM to DC, but it will effectively blunt any fancy waveforms.
I crawled through that a while ago and wrote up the results, which are more than anybody cares about:
