Post by thread:Frequency to voltage

Hello all, I am developing four axis micro stepping controllers using the '73. I am dealing with rates of 16000Hz-200000Hz with acceleration and de-acceleration. I need to capture my output with a DSO. To do so I need to convert the frequency to a voltage. So here is my question. I need a piece of test equipment that will convert freq. to voltage. Does anyone know a manufacture of distributor for a freq. to voltage converter? I know they exits, HP use to have one in their lab. Thanks in advance for your help. Be careful of the toes you step on today, They may be connected to the ass that you may have to kiss tomorrow. Take care spam_OUTjimhTakeThisOuTcalweb.com

Do you mean you wish to purchase one like the HP unit, or you want to build one using a specific part? The LM2907 and LM2917 are frequency-to-voltage chips(take one off that old full-height floppy drive). -Bob http://www.bobblick.com/
