Abstract
A test and measurement instrument including a voltage source configured to output a source voltage, a current sensor, and one or more processors. The one or more processors are configured to determine an estimation of a load of an unknown connected device under test based on the source voltage, the current sensor, and a voltage of the connected device under test without any prior knowledge of the connected device under test.
Claims20
A test and measurement instrument, comprising:
- a voltage source configured to output a source voltage;
- a current sensor configured to sense a current through a connected device under test;
- and
- one or more processors configured to determine an estimation of a load of an unknown connected device under test based on the source voltage, the current, and a voltage of the unknown connected device under test.
1 more element
A method for estimating an unknown load coupled to a test and measurement instrument, comprising:
- acquiring a voltage at a circuit node between a current sensor and a device under test, wherein the device under test presents the unknown load to the test and measurement instrument;
- determining an output voltage forced on the current sensor;
- determining a current through the device under test using the current sensor;
- and
- determining an estimated value of the load based on the voltage at the circuit node, the current, and the output voltage.
