Tek 577 Curve Tracer ( 177 Standard Test Fixture included)

Tekronix 577 Curve Tracer has a colleor supply variable from 0 to 1600 volts in several operating modes, including AC. The current available varies from 10A(20 A Pulsed) on the lowest voltage range to 40mA (80mA Pulsed) on the highest voltage range. The colleor supply power is set using a switch that changes series resistance to maintain the same peak power setting as the voltage range is changed. The colleor supply is automatically disabled when the vertical display exceeds 2.5 screen dimensions, helping to prote the device under test from destruive currents.
