Build a spectrometer for maximum frequency 10 MHz

Bagher Afsharian

Other Parts Discussed in Thread: ADC3224

Hello friends,

Would you please assist me in choosing a compact and low-cost (of course lowest possible) development/evaluation board or any alternatives for building a spectrometer?

Requirements:

The board must provide at least one output digital channel for sending the pulses with highest frequency of 10-11 MHz and two analog input channels for capturing voltage and current signals. I need sampling rate at least 10 times of highest frequency (100 MHz) in ADC and pulse generator with high switching frequency to generate good-shaped pulses.

Thank you,

Bagher

Bagher:

Check out the ADC3224 12-bit, 125 MSPS device. This is a dual but is low cost and low power. You can disable one of the channels if desired. This one should work nicely in your application.

Bagher,

Do you need control of the output pulse amplitude and duty cycle? You may need a DAC if that is the case. Also what is your digital interface on your digital processor? This may limit to your choice of converters.
