Attached is the corrected file of the data after the decimal. The average is -8598.25 which is .999991401 with the last 9 being -1 E-13. Bert Kehren

The "ONLY" thing we would like to do is record and display the info coming out of the RS post. To day making long term observations ties up a PC or Laptop with fans and a HP53132. Gone for a week the main concern is fan failure. Store the info on the Tablet in a SD chip or in it and when ready download through the USB port that we use for importing data to a memory stick for further processingThis counter is low power, no fan and has resolution that exceeded the ability of our sources. Not bad for a $120 device.We are presently experimenting using a ISC570 multiplier at 100 MHz and get 13 digits see attached but the data out of the back is only 12 digits reliable. Looking at averaging.13 digits frequency at 10 seconds even exceeds an 8607, only a saphire will do it.In the past we have run a few 570's at 200 MHz will try, that way we will be able to monitor the 5MHz output of a HP5065A with 5 E-14 resolution.To day running aging test we average a 24 hour run against GPS. Example HP5065A against Tbolt. We repeat the test in 20 days or a month..We also use a handy 10 psec. resolution long term monitor using a 2 channel counter modification that Richard MCC did for us 7 years ago. The counter we use with dual mixer. Bert Kehren In a message dated 10/1/2019 11:05:03 PM Eastern Standard Time, [email protected] writes: Bert, FA-2 uses serial emulation over USB with an FTDI chip. As far as I know, this is not supported under iOS. The best way to get serial data into an iOS device appears to be through a WiFi module. In this case, you would have to go from USB to WiFi, not very practical. Android supports serial via USB and through Bluetooth serial profile, so you have more options. To connect the FA-2 to an Android tablet, the FTDI chip should make it very easy. However, I am not sure what you want to do with the data in an Android tablet. Do you have software to process it? If so, it seems it would most likely support serial. Looking through the Play Store, I did not see anything timing-related but I did not spend much time looking. What are you interested in displaying?
