These instruments generate current pulses whose amplitude is largely independent of the load voltage. This makes
them ideal for pulsing device whose voltage may vary with time (for instance, the voltage drop of laser diodes may
vary with temperature, or explosive squibs which change impedance during ignition). This voltage independence is a
trade-off with speed. If faster rise times are required, consider using pulsed voltage
instruments instead.
To select the ideal pulser:
- Use the "Pick the Perfect Pulser" parametric search engine, or
- Use the selection table below, or
- Call us for advice (888-670-8729 or +1-613-686-6675).
Avtech can often customize pulse parameters and provide device socketing to meet particular requirements.
