Connecting to the Instrument

P5200A Probe
The P5200A probe requires an external AC adapter to power the internal circuitry. Install the P5200A probe as follows:
1. Connect the output of the probe to the BNC input of the oscilloscope or other measurement instrument. The
measurement instrument input must be ground-referenced (not floating).
2. Connect the power cord to the AC adapter.
3. Connect the output of the AC adapter to the DC input jack located on the output lead of the probe. All of the LEDs on the
probe briefly light to confirm power-on, and then indicate the settings from the previous session.
4. Adjust the vertical offset (or position) of the measurement instrument input.
5. Select the proper range setting. For example, when using the P5200A probe, to achieve higher resolution and less noise
when measuring signals below 130 V
output signal may not be accurate. Use the 500X setting instead.
If you want the oscilloscope to display the actual probe voltage instead of a scaled value, you must match the attenuation
setting of the oscilloscope to the probe attenuation setting. Use the on-screen Probe Setup menu on the oscilloscope;
the access method varies depending on oscilloscope model.
For example, on DPO/MSO4000 series oscilloscopes, press the front-panel channel number button and then press the
More button on the lower bezel until Probe Setup is highlighted. The oscilloscope attenuation setting displays in the
Probe Setup menu. Change the attenuation by turning the multipurpose knob.
WARNING. To avoid electrical shock, observe proper safety precautions when working with voltages above 60 VDC or
30 VAC . These voltage levels pose a shock hazard. Use only the accessories specified for the probe that you are using.

Make sure that the accessories are fully mated before connecting or disconnecting.
To avoid electrical shock or fire, make sure the test leads are in good condition. The input leads and extender leads have a
jacket wear indicator which becomes visible if the wire jacket becomes excessively worn. If the wear indicator is visible, do
not use the probe. Contact Tektronix Service for repair or replacement.
To avoid electrical shock or fire, keep the probe body and output cable of the probe away from the circuits being measured.
The probe body and output cable are not intended to be in contact with the circuits being measured.
6. Using the appropriate probe accessories, connect the inputs of the probe to the circuit points to be measured.
