Windowed triggering
Using the CompuScope 14100C’s ability to have two independent trigger sources which are ORed together, the
user can set up the triggering such that a trigger will occur if the input signal is outside a specified “window,” i.e.
it is higher than the upper limit or lower than the lower limit.

External Trigger amplifier
The External Trigger input also has oscilloscope-like 1 M
Ω
/ 35 pF input impedance.
Gage’s proprietary input-protection circuitry allows the FET stage to withstand voltages as high as
±
15 Volts
without causing any damage to the inputs.
The trigger comparators have an operating range of
±
1 Volt. Software-selectable attenuation of X1 or X5 on the
External Trigger input allows input ranges of
±
1 Volt and
±
5 Volt, respectively.
