(see below) to complete the mathematical

expression that represents the calculated

waveform you wish to display. Any

combination of waveforms of the same type

can be selected as the arguments of the

expression. Statistical data can only be

compared with statistical data, and likewise

time based data can only be compared with

time based data. Cross comparisons result

in an error condition.
