Hello forum,
I've been collecting data from a SRS PRS10 rubidium standard and utilizing the Stable32 program to graph results, etc. I'm having some difficulty in understanding the tau setting with regard to changing it and why.
Several of my data runs are for 2, 6 and 24 hours for the rubidium standard. I'm not using any GPSDO for steering for long-term corrections.
When I import the source data into Stable 32 I'm unsure as to what tau value to apply or if it even needs to be changed from the default. I realize, conceptually, that the tau value is a measurement of time, be it seconds, days or whatever. I'm looking at trying to verify the 1, 10 and 100 second ADEVs for this device according to SRS. I'm using Lady Heather 6.08b for the source data capture. I'm confident I have the multiplier values and a few other settings set correctly.
If I desire to say verify the 100s specification per SRS using a 24 hour capture file how is the tau value needing to be adjusted? The Stable32 program is quite robust and I would like to be reasonably sure of the data results. I did come across a helpful document authored by W. J. Riley, published in May, 2003. Once I digested that bit of material I'm still unsure of the tau setting(s) for the Stable32 application.
I would enjoy hearing from any and all about the tau settings for the app.
Thank you for reading through this.
