The P and P probe can also be used for other measurement tasks:. Damaged connection cables must be replaced! Click to learn more. Figure 3 P, current measurement on a single Vss pin Figure 4 P, current measurement on a single Vdd pin Figure 5 P, voltage measurement on a signal pin while this is in operation Figure 6 P, current measurement on a signal pin while this is in operation The external capacitor C ext can reduce the stress on the signal pin caused by the probe’s low impedance 1 Ohm Figure 6 during current measurements on signal pins.
The test IC is supplied via the test board and controlled via the connection board. The microscope camera Figure 19 optically detects if and when contact is made.

The P current probe head has an inductance L P of 1 nH in the line from the tip of the probe contact to the shunt.
Langer EMV-Technik 6196-74 will remedy any fault due to defective material or defective manufacture, either by repair or by delivery of replacement, during the statutory warranty period. Filter lec and bridges are located on the underside bottom of the test board to prepare the measurement set-up for contact with the probe Kec Figure 31 P characteristic. Read the explanation of the symbols on the unit in the operating manual.
The ICT1 automatic tester enables automatic measurements. Figure 20 Test set-up with the P probe set and ICE1 test environment without a control unit and microscope camera Figure 21 Pin contact visualised with the digital microscope camera 4. The “Curve” number is counted automatically Curve 3 under “Annotation”. The output of the matching network is connected to the 50 Ohm SMB port at the rear end of the probe.

The respective pin of the test IC can iwc contacted with the pin contact by moving the probe manually. The correction curve K is loaded to the “Corrections Selector” if the P probe is used for the measurement.
Shopbop Designer Fashion Brands. An additional capacitor C ext can be inserted between the test IC and the probe to reduce the stress on the signal pins caused by the 1 Ohm shunt. The input of the current probe head is connected to the probe’s pin contact Figure You can find the correction curve K in the “Corrections” list of the “Trace Manager”.
The input of the matching network is connected to the probe’s pin contact Figure The pin contact of the probe has to be brought into contact with the respective test IC pin to perform the measurement.
