Need off-the-shelf frequency signal conditioner


Thread Starter

Mehmet Alpay

Hi everyone,

I need a frequency signal conditioner for an application I'm working on. The frequencies I need to monitor range from 100 Hz to 5 KHz. The input pulses have amplitudes ~40 mV, but they are not "clean" by any stretch (i.e., they look nothing like the nice crisp square waves you'd get from a signal generator - oh well :). On top of that, the baseline voltage is slowly time-varying as well. Is anybody aware of an off-the-shelf signal conditioner I can use to convert these pulses to 0-5 V square pulses so that I can feed them into my frequency counter?

Thanks in advance for your help!

Almost any signal conditioning company can do this, but the best one I know of is the Red Lion PAX-I.

Try Red Lion controls. I just bought two for this same purpose. They are about $50.00 each
