AMETEK CTS UCS 200N
Manual for Operation V 2.41 21 / 54
Freestyle
The Freestyle menu makes it possible to program the rise time and the pulse duration of the generated transients
over a broad range. This enables to easy adapt the generators output pulses to new requirements.
It also allows the user to program his own specific test pulses, e.g. to test beyond the existing requirements.
This mode is used for pulses in the s and ms range for rise time and pulse duration. It can not be used for
programming parameters in the ns range.
Warning: The pulses in the Freestyle menu don't correspond to a defined standard!
The accuracy of the voltage, td and tr are depending on the pulse setting and the load. A “typical”
pulse in open circuit is the reference for the linearisation. Pulses with other parameters are more or
less accurate.
The exact pulse parameter must be checked by an oscilloscope. If there are differences, the user
must modify the setting till the measured pulse is correct.
STANDARD TEST ROUTINE FREESTYLE
The pulse parameters can be programmed within following range:
Pulse duration td (10% - 10%)
2, 4, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60,
65, 70, 75, 80, 85, 90, 95, 100, 200, 400, 450
Remark : For internal overload protection UCS 200N limits the output
voltage for
Rs = 2 Vmax = 150V
Rs = 4 Vmax = 330V
At the rear of the UCS 200N any resistor can be connected to realize
other values then listed above. An internal 10 resistor is in series with
the external resistance. (10 resistor is an internal overload protection)
Ri = 10 internal + external value
