| Abstract |
The Model 6487 Picoammeter/Voltage Source can be paired with a calibrated light source and a prob-
ing fixture to create a cost-effective photodiode test system. Multiple Model 6487s can be connected
to the DUT's probe pads to provide photocurrent readings or, with the addition of a switch matrix,
one picoammeter can take current measurements from multiple pads. In the first step of the meas-
urement process, performed in total darkness, the Model 6487 produces a voltage sweep and then
measures the resulting dark current. In the second step, a voltage bias is applied and the res...
