Merry X'mas and happy new year to every one!

i have a record like this:

record(ai, "17U:ES:ADC-01")
{
  field(SCAN, ".1 second")
  field(LINR, "LINEAR")
  field(EGUF, "10")
  field(EGUL, "-10")
  field(DESC, "ADC Site B Ch 1")
  field(PREC, "6")
  field(EGU, "Volts")
  field(HOPR, "10")
  field(LOPR, "-10")
  field(DTYP, "Hy8401ip")
  field(INP, "#C30 S0 @")
}


The hardware is hytec 8002 and hytec 8401 in VME crate which is used to collect the voltage from an ion chamber after an amplifier. When read the value directly there will have noise. I want to collect ten values and avrage them to putout. Is it possible to implement by a calc record?

Another thing i am confusing is the time. Epics support 0.1,0.2,0.5 and 1,2,5 seconds scan. The 8401 clock rate can be set at 100khz in max. If i need more higher frequency then 10Hz to obtain the record value, how can i do?

Thank you very much.
