Scaling
In the calculation of the delay, the measured delay between two pulses is scaled by a factor of 2
N
,
where –16 < N < 16, or N/16, where 0< N < 256. The former scaling is faster and a scaling of 1:1
is fastest. Scaling can typically be done at rates > 50 kHz.
The maximum delay between input pulses is 52 ms in hi-res mode (100 MHz) and 3.3 s in low-res
mode (100/64). The maximum delay resulting from the scaling and offset calculations is
respectively 21.47 s and 1374 s in hi-res and low-res modes. The delay must be positive.
