Measure lead TP-C812A

Measure lead TP-C812A

The Measure lead TP-C812A is a low noise differential measure lead designed to be used with the Handyprobe HP3. This 2 meter long measure lead splits in two individual ends of each 1.2 meter long. The special dual banana plug at one end plugs directly in the Handyprobe HP3. The two other ends each feature a single 4 mm banana plug , on which application specific test points, clamps or probes can be plugged.

The Measure lead TP-C812A is very flexible, uses a heat resistant silicone isolation and shrouded banana plugs.

The input of the Handyprobe HP3 is differential, which means that both sides of the input have a high impedance. There is no connection to ground as in conventional oscilloscopes which are used with coax cables. Using a coax cable on the Handyprobe HP3 would result in the Handyprobe HP3 picking up a lot of external interference.


The specially designed Measure lead TP-C812A has a high Common Mode Rejection Ratio (CMRR), it is very insensitive to external interfering signals. The two ends can be placed up to more than two meters apart, while picking up very little interference. With a conventional oscilloscope with a standard oscilloscope probe this is not possible. The maximum distance between the positive side and ground of a standard oscilloscope probe is usually limited to approximately 20 cm. The Measure lead TP-C812A for the Handyprobe HP3 does not have this disadvantage. External interference is very well suppressed by the special construction of the Measure lead TP-C812A. Measuring between two distant points is now possible.

The table below shows detailed specifications of the Measure lead TP-C812A.
