Input Linear Dynamic Range The probe head amplifier used by the P6243 Active Probe has a limited linear operating range. To keep the input linearity error less than 4% you must limit the signal input voltage to ±8 V (DC + peak AC).
Probe TEKPROBE Cable Interface Figure 5: P6243 Simplified Schematic Diagram Probe Head and Cable Assembly The probe head assembly contains an active amplifier circuit that buffers and amplifies the input signal. The amplifier receives power from the compensation box assembly via the cable assembly. All signal amplification and buffering is performed in the probe head assembly.

1. Connect the test equipment as shown in Figure 7. 2. Attach the probe to a TEKPROBE interface on the 1103 power supply. 3. Set the 1103 offset VAR/0V to 0V. 4. Set the multimeter to read DC volts. P6243 Service Manual...
Terminator BNC to Dual Banana Adapter Figure 7: P6243 DC Attenuation Accuracy Setup 6. Set the power supply to +2.000 V. (This setting will be referred to later on as Vmax). 7. Record the value measured by the multimeter as M1. (With the 10X attenuation of the probe, the voltage measured will be about +0.200 V.)

10. Determine the percent error by using the formula below: %Error = [ M1 − M2 − 1] × 100% The calculated error should be ≤2%. NOTE. An unacceptable error value may result if a low tolerance termination is substituted for the recommended termination. P6243 Service Manual...
Maintenance This section details the maintenance, repair, and troubleshooting procedures for the P6243. Replacing TEKPROBE™ Interface Pins TEKPROBE interface pins can stick and fail to make contact after time. Periodically check to see that each of the interface pins move freely and fully extends out of the interface.
2. Hold the open edge apart, and use the tool to open the other side of the compensation box. 3. With both sides of the box open, gently separate the two halves of the compensation box. Cover Catches Figure 9: Removing the Compensation Box Covers P6243 Service Manual...
