This feature is optional and requires the software key be programmed to enable it.

Sine Resonance control tracks a resonance frequency by adjusting the driving frequency so that the
relative phase between two input channels is 90 degrees (1.57 radians). This type of test is usually
done with the channel 1 accelerometer mounted on the fixture and the other accelerometer(s) mounted
on the product at the location(s) at which you want resonance induced.
