Transition Noise
Transition noise is defined as the jitter in the transition between two steps.
Due to the nature of the measurement principle (Hall sensors + Preamplifier + ADC), there is always a certain degree
of noise involved.
This transition noise voltage results in an angular transition noise at the outputs. It is specified as 0.12 degrees rms (1
sigma) *1 .
This is the repeatability of an indicated angle at a given mechanical position.
The transition noise has different implications on the type of output that is used:
Absolute output; SSI interface:
The transition noise of the absolute output can be reduced by the user by applying an averaging of readings.
An averaging of 4 readings will reduce the transition noise by 6dB or 50%, e.g. from 0.12°rms to 0.06°rms (1
sigma).
PWM interface:
If the PWM interface is used as an analog output by adding a low pass filter, the transition noise can be
reduced by lowering the cutoff frequency of the filter.
If the PWM interface is used as a digital interface with a counter at the receiving side, the transition noise
may again be reduced by averaging of readings.
Incremental mode:
In incremental mode, the transition noise influences the period, width and phase shift of the output signals A,
B and Index. However, the algorithm used to generate the incremental outputs guarantees no missing or
additional pulses even at high speeds (up to 30,000 rpm and higher)
*1
: statistically, 1 sigma represents 68.27% of readings,
3 sigma represents 99.73% of readings.
