freq cntr type 1




freq cntr type 2







icm 7216 10 mhz freq cntr with prescaler and regulater
final 60 mhz range
 

                                                     workbench in shop


                                                 8 digit cntr

                                                     
                                                   8 digit cntr



                                                  9 digit cntr


                                                  counter module 10mhz


                                               3 ghz counters


                                                                solid state oscope 25mhz


                                          pocket oscope 500khz


                                     prototype unit dvm  power supply and freq cntr




                                  9 digit counter good to 140mhz without prescaller input counter 74s196
                                  good to 140 mhz   input amps mmic msa 0486 (800 mhz) on ch 1

                                       ch 2  mc01080  1 ghz  divide by 10 and msa 1486  (3ghz)




                     10 mhz time base store/clear for freq counters using discrete ic's in above unit




                                          200 mhz oscope from ebay works great
