    Technical SPA100 Bias Generator The bias generator output of the SPA100 is a low power class A amplifier. It is primarily design to provide a bias voltage for photodiodes in low-current measurement situations. The output impedance is 2.7Kohms, this is after the feedback network, so some drop should be expected depending on load impedance.
