Abstract:
1. An electronic load device, provided for testing an OT (power source product to be tested), comprising: a central process unit (CPU); a voltage-current measurement unit, to measure an output impedance of the OT and output the output impedance signal to said CPU; a power stage connected with the OT so that said power stage is simulated as a load for the OT; a control module receiving a first signal and a second signal from said CPU so as to control said power stage, wherein said first signal is a current pulled out command, and said second signal is a bandwidth range setting command; an impedance-bandwidth table connected with said CPU; so that said electronic load device can regulating an bandwidth range according to the output impedance of the OT, after the output impedance of the OT is measured.
