(10) Repeat technique of (8) (a) through (d) above for remaining TI voltage outputs
and WAVE FORMs in table 4.
NOTE
Limits in table 4 were calculated using manufacturer's formula
(0.5 x Vp-p x 0.999917). 0.999917 (83 ppm) compensates for
the finite transition time of the square wave and the resultant
fall in its RMS value.

To avoid "load <50k
detected" warning message, set OUTPUT to OFF, change waveforms, then set
1
OUTPUT to ON.
(11)Set TI OUTPUT to OFF.
(12) Disconnect active head at multimeter, insert 50
feedthrough termination and
reconnect to multimeter.
