The Tektronix P6231 is a Low Circuit Loading Signal Acquisition probe for CSA, DSA, 11000 Series, and the TDS Family of Oscilloscopes.
The Tektronix P6231 Bias/Offset probe acts as a standard 500 Ω passive divider voltage with the additional capability of having an adjustable tip nulling voltage. This feature reduces the DC-Loading effects of the probe when it is used to measure signals whose mid-voltage value is not at zero volts, or in circuits where the termination impedance is not returned to ground level. The Input Bias/Offset Voltage may be adjusted so that the voltage at the probe input resistor is equal to the test signal potentional; thus, no DC current flows through the probe's input resistor.
These Active Probes may also be used with 50 Ω or 1 MΩ oscilloscope systems, with conventional BNC interfaces, via the 1103 TEKPROBE Power Supply. The 1103 has dual TEKPROBE inputs, dual BNC signal outputs, and dual voltage offset on/off switches and potentiometers.
