How to read out APD from pixel clock?

[shfxu]

I am using Galvo scanner to image sample. The detector is APD module with analog output. Galvo will send out pixel clock. The time interval between pixel clock is about 50ns. The AO of APD should be recorded at each pixel clock, about 50ns. Can any one tell me which DAQ board should have the function to use the pixle clock trigerring APD and save APD signal?  Thanks.

Hi Shifa,

It sounds like you want to acquire an analog input at 20MS/s (50ns clock is 20MHz).  What resolution are you looking to use?  Our DAQ boards are probably going to be too slow for your scenario, and you may want to look at some of the high-speed digitizers.
