kenjiArai 13:1041596c416c 19 Frequency Counter Functions
kenjiArai 13:1041596c416c 20 Mesurement frequency range:
kenjiArai 13:1041596c416c 21 10Hz to 100MHz (BNC Connector)
kenjiArai 13:1041596c416c 22 Extended range:
kenjiArai 13:1041596c416c 23 Up to 1GHz (1/10 prescaler) or more over (1/20) (SMA)
kenjiArai 13:1041596c416c 24 Gate time:
kenjiArai 13:1041596c416c 25 1 sec to 4095sec (extend to more if RAM is avairable)
kenjiArai 13:1041596c416c 26 Reciprocal measurement:
kenjiArai 13:1041596c416c 27 0.01Hz to 5KHz (extend more lower frequency change input I/F)
kenjiArai 13:1041596c416c 28 Base Internal Clock:
kenjiArai 13:1041596c416c 29 50MHz VCTCXO (Connor-Winfield TB514-050.0M)
kenjiArai 13:1041596c416c 30 1 PPS:
kenjiArai 13:1041596c416c 31 GPS receiver(u-blux7/NEO-7) with an external antenna (SMA)
kenjiArai 13:1041596c416c 32 Temperature controlled Oven:
kenjiArai 13:1041596c416c 33 32 degree Celsius +/-0.2 for 50MHz VCTCXO & 3.3V regulater
kenjiArai 13:1041596c416c 34 Hardware Configration
kenjiArai 13:1041596c416c 35 frequency input: PC_6 & PA_3
kenjiArai 13:1041596c416c 36 50MHz base clock input: PA_5
