The best way to illustrate the use of EG is with three worked tutorials.

8.3.1. Tutorial 1: Simulated auditory response and duration measurement using a

voice key

In this example we want to generate simulated audio responses using the BBTK Digital

Tone Generators. Ideally before we start we would check that we had adjusted the pitch

and amplitude of each tone generator so that it was at an acceptable level. Do this by

pressing “F3” to bring up the “Output line Check” box – simply click the LED on/off for the

line you wish to check. Alternatively select “Tools|Output line Check” from the menu.

Finally we would place the unit near to the microphone on the remote PC and check that it

triggered as intended.

In this example we are going to use a Tone Generator plugged into powered-out line 5 of

the BBTK.

At first glance the layout may seem complex. However, we only need to make use of the

four “Port Value” LEDs in the upper grid together with a duration entry.
