What is the allowable amount of crosstalk between channels of a 30-Series PowerLab?

The allowable amount of crosstalk between channels is 75 decibels minimum.  To calculate whether your particular PowerLab meets this specification apply a signal to the Primary Channel, measure the amplitudes of the signals in the Primary and Crosstalk Channels, and use the following equation:

Crosstalk in decibels = 20 x log( Primary Channel / Crosstalk Channel )
