The general purpose filters run at the fastest execution rate available in the product.
This is the same rate at which bridge feedbacks are collected, the fastest regulators
are operated, and hardware commands are issued. The filter execution rate is
generally faster than the 1-millisecond rate at which the application functions and the
LAN communications occur.

Oscillator
Each Innovation Series product contains a diagnostic oscillator. The oscillator
switches between a positive value and a negative value, spending the same amount
of time at each level. The oscillator can be used as a reference signal source for test
purposes.
Function outputs
The following table specifies the output variables of the Oscillator function.
Variable Description
Sqr wave osc output Oscillator square wave output
Function configuration
The following table specifies the configuration parameters of the Oscillator function.
Parameter Description
Oscillator neg mag Magnitude of the negative portion of oscillator output
Oscillator pos mag Magnitude of the positive portion of oscillator output
Oscillator 1/2 cycle Time that defines half of the oscillation period, sec
Oscillator enable Enable oscillator
Function description
The Oscillator function produces a square wave output that switches between a
positive value and a negative value. The function can be enabled or disabled via the
parameter, Oscillator enable. The output levels and the period of the square wave are
configurable. The following diagram shows how the configuration parameters
generate the oscillator output.
