Probe Operating
Information
Probe Operati
The P5200A Series probes share many common features, including connections to the circuit, compensation box buttons,
and operating basics. The probes connect to the host oscilloscope through one of two probe-to-oscilloscope interfaces:
BNC – this connection is a shielded 50 Ω coaxial cable with an outer ground connection and center signal pin. The BNC
interface is used on the P5200A probe, which allows you to connect directly to most ground-referenced oscilloscopes.
TekP r o be
the probe tip. This interface is used on the P5202A, P5205A, and P5210A probes, and many Tektronix oscilloscopes.
These probes can also be used with Tektronix oscilloscopes that use the TekVPI-interface, by connecting through an
optional
TPA-BNC Adapter
Level 2 – this interface adds probe communications with the oscilloscope to accomplish calibrated offset at
TPA-BNC Adapter.
ng Information
The TPA-BNC Adapter is an optional accessory that enables you to use existing TekProbe-interface probes with oscilloscopes
that feature the TekVPI probe interface. The adapter recognizes TekProbe-interface probes and supplies the necessary
power, serial communication, and offset control as used by the connected TekProbe product accessory.
WARNING. To reduce risk of shock or fire, do not exceed the ratings of the TPA-BNC adapter; it is not intended to be
connected to voltages above 30 VAC, 42 Vpk, or 60 VDC. F or BNC probes, connect the probe directly to the oscilloscope.
1 P5200A Series High Voltage Differential Probes Instruction Manual
Connecting to the Instrument
P5200A Probe
The P 5200A 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).
Probe Operating
Information
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. A d just the vertical offset (or position) of the measurement instrument input.
5. S elect the proper range setting. For example, when using the P5200A probe, to achieve higher resolution and less noise
when measuring signals below 130 V
, switch the attenuation to 50X. If the overrange indicator lights or flashes, the
pk
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 attenuatio n by turning the multipurpose knob.
WARNING. To avoid electrical shock, observe proper safety precautions when working with voltages above 60 VDC or
30 VAC
. T hese voltage levels pose a shock hazard. Use only the accessories specified for the probe that you a re using.
RMS
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 prob
e 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.
P5200A Series High Voltage Differential Probes Instruction Manual 2
Probe Operating
Connecting P5202A, P5205A, & P5210A Probes to Oscilloscopes that feature the VPI Interface
1. Connect the TPA-BNC adapter to the oscilloscope.
Information
2. Connect the probe to the input of the adapter.
3. Turn the probe connector clockwise to secure it. 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 oscilloscope input.
NOTE. Do not attempt to adjust the offset adjustment in the probe compensation box; it is factory-preset to optimize the
range of the electronic adjustment. To make the offset adjustment, refer to the procedures. (See page 45, Offset Zero.)
5. Select the proper range setting. For example, when using the P5202A probe, to achieve higher resolution and less
noise when measuring signals below 64 V
, switch the attenuation to 20X. If the overrange indicator lights or flashes,
pk
the output signal may not be accurate. Use the 200X range setting instead.
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 with the probe that you are using.
RMS
Make sure that the accessories are fully m ated before connecting or disconnecting.
WARNING. 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.
6. Using the appropriate probe accessories, connect the inputs of the probe to the circuit points to be measured.
WARNING. 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.

Probe Operating
Information
Probe Controls
The P5200A Series probes have s everal features that make probing and measurement a simpler task. F am iliarize yourself
with the controls shown on the following pages. The attenuation ranges differ between probe models.
Overrange Indicator
The overrange indicator lights red if the
voltage of the input signal exceeds the
linear range of the range setting. When this
happens, the signal on the probe output
does not accurately represent the signal on
the probe input.
WARNING. The Overrange indicator
does not detect overrange condition of
common-mode voltages or voltage-to-earth
potential at the probe inputs. The Overrange
indicator only detects differentially between
the + and – inputs (not relative to ground).
Do not exceed the common-mode voltage
or input voltage-to-earth ratings of the probe
when taking measurements. (See page 27,
Overrange Detection.)
If you are not sure, make a single-ended
measurement of each point you are intending
to measure differentially first. Make a
single-ended measurement by tying one
input lead to ground (the "–" input) and then
connecting the other lead (the “+" input) to
the points of interest, one at a time.
Attenuation Button and Indicators
Press the button to select between the
voltage range (attenuation) settings of the
probe. The range is indicated by two LEDs
on the probe and may be displayed on
the oscilloscope screen, depending on the
oscilloscope model.
P5200A models only: 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 to change the setting.
The Overrange LED lights if the applied
voltage exceeds the selected range. To
extinguish the LED, select a higher range.
If a higher range is not available, do not
attempt to take the measurement.
