Operating Examples
Fixed transition mode
The fixed transition time ( 5 ns ), is ideally suited for step response
measurements such as:
•
Transient behaviour of amplifiers (transient time, overshoot,
ringing, settling time).
•
Reverse recovery time of transistors and diodes.
•
Characterization of capacitors (equivalent serial resistance,
inductance, high frequence capacitance).

Capacitance circuit
Linear transition mode
lndependantly variable leading and trailing edges between 6.5 ns and
95 ms can be used to generate ramps or sawtooth waveforms for:
•
Stimulation of hydraulic or pneumatic devices
•
Mechanical tests
•
Hysteresis of Schmidt trigger circuits
•
Stress testing of capacitors and thyristors by measuring maximum
allowed voltage increase per time (max. dV /dt)
Cosine shaped translUon modes (Gaussian)
Independantly variable cosine shaped leading and trailing edges
between 6.5 ns and 95 ms can be used to generate smooth transitions
which do not include high frequencies for:
•
Communications, reduced reflections and crosstalk
