The ASM303 does not need any specific calibration.

P201, which should nominally be set to its approximate mid-position, but can be trimmed to adjust the sampling rate. Increasing the sampling rate will allow the [ENVELOPE] output to closer follow the [IN] signal envelope but will also increase the amount of ripple super-imposed onto the output. Reducing the sampling rate will reduce the super-imposed ripple but will cause the output to be less accurate in the following the input signals envelope.

The user should adjust P201 for the best response suited to their needs. An oscilloscope such as our ED702 is needed to perform this adjustment
