About the Random Function Command Type
The function generator’s Command Type selection of Random provides random functions with various
pre-emphasis filters. Typically, these random wave shapes are used to train adaptive compensators such as
AIC and APC.
The convergence rate is typically slower at high frequencies. The random function pre-emphasis filter is used
to make the convergence rate constant over all frequencies, by boosting high frequencies and suppressing
low frequencies. When training an adaptive compensator, choose a shape that is roughly an inverse of the
shape of the signal spectrum.
The options are:
• Random - 1/F2
• Random - 1/F
• Random - Flat (no pre-emphasis filter)
• Random - F
• Random - F2
External Command
About External Command Inputs
Your controller can process programming received from an external controller or function generator while
maintaining all other closed-loop control functions.
Note:
Your controller cannot recognize mode switches in external program input signals.
External Command Settings
Use this control panel to select and adjust external program commands.
You must use the Station Builder application to assign an external input to a channel in the station configuration
for this panel to display.
