Set OUTPUT GAIN to x1.
Set FILTER to 100 kHz.
Connect scope to SCALED OUTPUT BNC.
Trigger scope from waveform generator.
Set scope to 0.2 V/div, 1 ms/div.
Apply a 10 V
p-p
100 Hz triangle wave to the SPEED TEST BNC.
On the scope you should see about a 1 V
p-p
square wave.
If the square wave response is unacceptable in terms of rise time or linearity continue with
procedure, otherwise move on to RESET TRANSIENT COMPENSATION.
