AVTECH AVX-S3A

Model AVX-S3A is designed to match 50 Ohm pulse generators such as Model AVO-2-C to 12 Ohm loads with peak currents of 5 Amperes. Consequently, the resistor RS in the equivalent circuit for this model is normally 10 Ohms. The series resistance of the laser diode and the resistor (RDIODE + RS) must equal the pulse generator source impedance divided by N2. Consequently, if the series resistance of the laser diode is relatively high, it then maybe necessary to reduce the value of RS. Model AVX-S3B is designed to match 50 Ohm pulse generators such as Model AVO-5-C to 3 Ohms and will provide peak diode currents up to 28 Amperes. Model AVX-S3C is designed to match Models AVO-2W-C and AVO-2-C (25 Ohm source impedance) to load resistance of about 5 Ohms and will provide peak diode currents as high as 10 Amperes. Model AVX-S3D is designed for use with Model AVO-5B-C and will provide up to 48 Amperes of diode current. All AVX-S3 units include two-foot-long input cables with SMA male connectors.
