Description
What can you measure with a differential probe?
With 20 MHz bandwidth, a switchable attenuation of 20:1, and 200:1 (part no. ADF25), you can measure high-voltage circuits, motor speed controls, power supply design, and high-power electronic converters.
What comes in the probe set?
You will receive one differential probe, 2 probe tips, and 2 retractable sprung probes for accessing small wires for measurements.
Why is common rejection ratio (CMMR) important for differential probes?
CMMR is a measure of how well a differential probe will reject signals common to both test points, leaving the desired signal to be displayed by the scope.
What does the maximum differential voltage specification tell me?
This specification provides you with the maximum voltage between the inputs the differential probe can be subjected to. This is important because the maximum voltage should never be exceeded.
What is input impedance?
Impedance is a measure of how much a signal will be restricted. In general, it is best to have high resistance and low capacitance to ensure signal quality, accuracy of tests, and to ensure the probe doesn’t load down the circuit under test.
