Probe Operating
Information
Probe Operati
The P5200A Series probes share many common features, including connections to the circuit, c ompensation 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 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.
TekProbe 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 re, 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. For BNC probes, connect the probe directly to the oscilloscope.

Probe Operating
Information
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 oating).
2. Connect the power cord to the AC adapter.
3. Connect the output of the AC adapter to the D C input jack located on the output lead of the probe. All of the LEDs on the
probe briey light to conrm 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 Make sure that the accessories are fully mated before connecting or disconnecting.
To avoid electrical shock or re, 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.

does not detect overrange condition of common-mode voltages or voltage-to-earth potential at the probe inputs. The O verrange 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.)
Probe Operating
Information
If you are not sure, make a single-ended measurement of each point you are intending to measure differentially rst. 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.

Press the button to limit the probe bandwidth to 5 MHz. 5 MHz is close to the switching frequency of most switching transistors (FETs) in switch mode power supplies (SMPS).
The 5 MHz lter assists in the characterization and testing of power supplies in switch mode by removing all high frequency content, noise and harmonics from the measurement.

Operating Characteristics and Probing Techniques
This section explains the operating characteristics of the P5200A Series High Voltage Differential Probes and includes techniques
Operating Limits
The probes have two operating ranges that you select with the ATTEN button. These ranges set the maximum differential voltage that can be measured. The ranges and voltage limits differ between probe models. (See Table 3.)

The input signals that you attempt to measure must be considered both for the differential potential between each other and for the amplitude on each input with respect to ground (the common mode voltage specication). The maximum common mode voltage limits vary between probes, from 450 V for the P5202A, to 2300 V for the P5210A probe. You should consider both specications when choosing a probe for your measurement task. Some examples that illustrate this are shown on the following pages.

Operating Basic
Overrange Detection
Differential voltage outside the operating range will overdrive the circuitry of the probe and distort the output signal. When this differential overrange occurs, the probe detects the condition and lights the overrange indicator. With the Audible Overrange ON, the probe will also emit an audible alarm.
WARNING. The Overrange indicator does not detect an 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.
If you are not sure, rst take a single-ended measurement of each point that you are intending to measure differentially. Take 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.
Common-Mode Rejection
The common-mode rejection ratio (CMRR) is the specied ability of a probe to reject signals that are common to both inputs. More precisely, CMRR is the ratio of the differential gain to the common-mode gain. The higher the ratio, the greater the
f probe to reject common-mode signals.

Twistin
Twisting the input leads helps to cancel noise from high-EMI environments that is induced into the input leads.
de rejection decreases as the input frequency increases. For example, if you apply a 60 Hz line voltage of
to both input leads of the probe, the probe rejects the signal by 80 dB (typical) and the signal appears as only a

Probe Loading
When you touch your probe tip to a circuit element, you are introducing a new resistance, capacitance, and inductance into
e circuit. Frequency and impedance of the source determine how much the probe loads the circuit you are measuring. As
th the frequency of the source starts to increase beyond 1 kHz, the input impedance of the probe begins to decrease.
The lower the impedance of the probe relative to that of the source, the more the probe loads the circuit under test. For a graph of frequency versus input impedance, refer to the Specications section. As the graph shows, the probes have virtually
loading effect on sources with relatively low impedance and low frequency.

Specication
The specications shown apply to the P5200A Series probes installed on Tektronix MSO/DSO4000 oscilloscopes. When a probe is used with another oscilloscope, the oscilloscope must have an input impedance of 1 Mand a bandwidth equal to or greater than the probe. The probe must have a warm-up period of at least 20 minutes and be in an environment that does not exceed the limits described. (See Table 5.) The probe calibration should be run on the host instrument before verifying the warranted probe specications. Specications for the P5200A Series probes fall into three categories: warranted, typical, and nominal characteristics.

Troubleshooting
Host Instrument Firmware
Some instruments may require a rmware upgrade to support full functionality of the latest probes that are offered by Tektronix. Instruments with lower versions of rmware may not display a ll probe controls and indicators on screen, and in some cases m ay require you to power-cycle the instrument to restore normal instrument operation. If you are having problems with your probe and suspect that you need to upgrade your instrument rmware, go to www.tektronix.com/probe-support to download the latest rmware.
To check the rmware version on W indows-bas ed instruments, from the menu bar, click H elp/About TekScope. On Linux-based instruments, press the Utilities button on the front panel.
Error Conditions
LEDs Do Not Remain Lit
If none of the LEDs remain lit after you connect the probe, a probe/oscilloscope interface fault may exist. Perform the following steps until you clear the fault or isolate the problem:
If you are using a P5200A probe, check that the DC adapter is plugged in and functional.
Disconnect and reconnect the probe to restart the power-on diagnostic sequence.
Connect the probe to a different channel on the oscilloscope.
Disconnect the probe from the oscilloscope, power-cycle the oscilloscope, and then reconnect the probe.
Connect the probe to a different oscilloscope.
If the symptoms remain (they follow the probe), then the probe is defective and must be returned to Tektronix for repair.

Cleaning
Protect the probe from adverse weather conditions. The probe is not waterproof.
CAUTION. To prevent damage to the probe, do not expose it to sprays, liquids, or s olvents. Avoid getting moisture inside
the probe when cleaning the exterior.
Clean the exterior surfaces of the probe with a dry, lint-free cloth or a soft-bristle brush. If dirt remains, use a soft cloth or swab dampened with a 75% isopropyl alcohol solution. Use only enough solution to dampen the cloth or swab. Do not use abrasive compounds on any part of the probe.
