Howdy!

Or maybe I'm not using the oscilloscope properly. I have a coax connected to the chan1 input, which I stripped and connected to the output of the driver where the laser diode would go. I tried it with just the scope, and also with a dummy load attached but get nothing. Multimeter is showing a...

My DC power supply is adjustable but jumps from 4.5v to 6vdc @ 1amp. From the DC PSU I hooked + to one side of a 10k pot and - to the other side of the 10k pot... the middle pin I connected to a 1kohm resistor. The other side of the resistor was then connected to the analog mod input but doesnt...

What is the best way to test analog modulation without a DAC / ilda controller? I have an oscilloscope but not sure what to use for analog input.

Re: The real high power and full range DIY laser diode driver *updated!* Correct on the 5v analog modulation input. You're my hero! I'll buy a round if it works :beer: Just to make sure... not TTL/PWM, but true analog modulation :) Closest I have come yet is asking newark if they might be able...

Re: The real high power and full range DIY laser diode driver *updated!* Any chance on adding analog modulation? I think everyone is waiting for the flexmod to come available again... would be nice to have a diy instead :)
