Hi, I am testing my 53132a counter floor. Connecting the 10Mhz rear output to Channel A, and reading ADEV with Timelab in frequency mode. Attached picture shows first results.
We see log-log lines with a -0,5 slope, and a vertical spacing ratio consistent with (Tau0)^2 (Tau0 = actual gate time given by Timelab) I understand the 1/square(Tau) slope of the lines, as RMS resolution is enhanced with the length of samples (And ADEV # RMS of fractional frequency in this configuration) But I don’t understand the (Tau0)^2 spacing ? According to the counter manual, RMS resolution should be proportional to 1/(Tau0 x square(Tau)) so not to 1/(Tau0^2) I looked at literature, including Rubiola and many others but could not find the answer. Any clue ?
