The simple encoder mode can be selected by choosing the Event counting + Basic encoder counting. First let's set up the encoder. Signal A is Source_B0_CNT0, Signal B is Aux_CNT0 and Signal Z is Gate_CNT0 
. We set the Encoder mode to X1 
and the Input filter we set to match our highest frequency 
. We can also enter the scaling factor - if the user has an encoder with 512 pulses, the units could be entered as revs for example, so we would enter that 512 counts equal 1 rev.

Now let's take some measurements. The output of this counter is the one that which counts up when signal A leads signal B, and counts down when signal B leads signal A. The positive edges of signal A is used to calculate the counts 
.

If we choose X2 mode in the setup, the counter will count raising and falling edges of source A 
, therefore the resolution will be increased by a factor of 2. Also, the scaling should be changed accordingly. Instead of 512 counts per revolution, we need to enter 1024 counts per revolution.

| Analysis - X2 encoder mode |
X4 mode counts the rising and falling edges of signal A as well as signal B 
. The resolution of the measurements is therefore increased by a factor of 4, so in this case, the user should enter 2048 counts per revolution as the scaling factor.
