The Tektronix P 6139 A is a 10X passive probe. The Tektronix P 6139 A is designed for use with Tektronix TDS3000 and TDS500 Series digitizing oscilloscopes. The Tektronix P 6139 A has a 1.3 meter cable.[1]
What it is
The P6139A is a 10X passive voltage probe designed for use with digitizing oscilloscopes. Passive voltage probes connect an oscilloscope to an electronic circuit while providing a fixed attenuation of the signal.[1][3]
The P6139A is designed for use with Tektronix TDS500, TDS600, TDS700, TDS3000B, and TDS7000B Series oscilloscopes. The probe has a 1.3 meter cable and is fully compatible with Tektronix compact-size (3.5 mm) probe accessories.[1][3]
How it works
Passive voltage probes use a resistive-capacitive divider network to attenuate the input signal by a fixed factor. The P6139A provides 10X attenuation, reducing the signal amplitude by a factor of ten before it reaches the oscilloscope input. Attenuation readout encoding allows the oscilloscope to automatically recognize the probe's attenuation factor.[3]
The P6139A includes a low-frequency compensation adjustment accessible through an opening in the compensation box. The user adjusts the trimmer while observing a 1 kHz calibrated square wave until the displayed waveform shows a perfectly flat top. Proper compensation matches the probe's capacitance to the oscilloscope's input characteristics.[1]
The P6139A uses hybrid/SMT circuitry and modular construction. The probe head and cable assembly are smaller than traditional passive probes, and the probe is compatible with a full line of compact attachment accessories.[3]
Where it fits in the process flow
The P6139A is suited for high- and low-frequency relative measurements. Typical applications include design, service, and manufacturing environments where accurate signal observation is required.[3]
