P5200 Instruction Manual
Features and Accessories
The P5200 High Voltage Differential Probe provides a safe means of
measuring circuits with floating potentials up to 1,000 VRMS CAT II from
earth ground and up to 1,300 V (DC + peak AC) differential. This probe
must be connected to an oscilloscope or other measurement instrument
in which the input BNC connector is at ground potential. The probe is a
safe alternative to the extremely dangerous practice of disconnecting
the oscilloscope ground to achieve a floating measurement.
The P5200 probe allows clear and accurate measurements of high-speed
transitions and provides excellent common-mode rejection of noisy
signals. Both inputs have high impedance and low capacitance. Because
of these features, the probe can safely measure the fast voltage transients
in switching power devices such as IGBTs, power MOSFETs, thyristors,
GTOs, and bipolar transistors without damaging these devices.
Other applications for the P5200 probe include testing high-voltage
motor control circuits and line connected circuits in switch-mode power
supplies.
WARNING. To avoid an electric shock, do not use the P5200 High
Voltage Differential Probe with oscilloscopes that have floating inputs
(isolated inputs), such as the Tektronix TPS2000 series oscilloscopes and
THS700 series oscilloscopes. The P5200 High Voltage Differential Probe
requires an oscilloscope or other measurement instrument with a grounded
input.
WARNING. To avoid RF burns, do not handle the probe while the input
leads are connected to circuits above the voltage and frequency limits
specified. (See page 9, Safety limits.) Use only probe accessories that are
rated for the application.
CAUTION. Do not use the P5200 High Voltage Differential Probe above
1,000 VRMS CAT II from ground on either input or ± 1,300 V (DC + peak
AC) between the leads.

P5200 Instruction Manual
Features and Accessories
The P5200 has several features and accessories that make probing and
measurement a simpler task. Take a moment to familiarize yourself
with these items and their uses.
Power Indicator. The power indicator lights green
to show that power from the AC adapter is present.
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.
Range Button. In the raised position the
range button sets the attenuation to 1/500. In
the lowered position the range button sets the
attenuation to 1/50.
Use the 1/500 position for connections above
130 V up to a maximum of 1,300 V differential.
Use the 1/50 position for better signal resolution
on connections below 130 V (DC + peak AC).
Both range settings are rated for a maximum of
1,000 VRMS CAT II common mode.
Scale Conversion Chart. The chart lists the
effective volts per division for the 1/500 and 1/50
range settings and scale factors of 2 mV to 1 V on
the measurement instrument.
The effective volts per division is the attenuation
factor of 500 or 50 multiplied by the scale factor
of the measurement instrument. For example,
with the range set to 1/500 and the measurement
instrument sensitivity set to 0.5 volts/division, the
effective volts per division equals 500× 0.5 or
250 V.
Differential Inputs. The inputs accept a maximum
of 1,000 VRMS CAT II between either input and
ground and a maximum difference of 1,300 V
(DC + peak AC) between the inputs. These input
ratings are valid for both range settings.

instrument input.
5.
Select the proper range setting. For higher resolution and less noise
when measuring signals below 130 V, switch the attenuation to
1/50. If the overrange indicator lights or flashes, the output signal
may not be accurate. Use the 1/500 setting instead.
6.
Set the volts per division setting on the measurement instrument to
the range indicated in the table on the front panel of the probe.
WARNING. To avoid electrical shock, observe proper safety precautions
when working with voltages above 60 VDC or 30 VACRMS. These voltage
levels pose a shock hazard. Make sure that the test leads are in good
condition. Use only the accessories supplied with the P5200 probe.
7.
Using the appropriate probe accessories, connect the inputs of the
probe to the voltage source.

Operating Basics
Minimizing Risk of RF Burn (probe leads)
WARNING. To avoid personal injury, do not handle the probe leads when
the leads are connected to a source that is above the voltage and frequency
limits. (See page 9, Safety limits.) The area above these limits poses a
risk of radio frequency (RF) burns.
If you need to use the probe within the risk area for RF burn, power off
the source before connecting or disconnecting the probe leads.
Maximum Input Limits
CAUTION. To avoid damaging the input circuitry of the P5200 probe, do
not apply a voltage that is more than 1,000 VRMS CAT II between either
input and ground or more than 1,300 V (DC + peak AC) between the two
inputs. Above 3 MHz, the voltage limit decreases as frequency increases.
(See page 9, Safety limits.) The input limit applies to both the 50X and
500X settings.

Operating Basics
Operating Characteristics and Probing Techniques
This section explains the operating characteristics of the P5200 probe
along with techniques you can use to maximize the performance of
the probe.
Operating Limits
The P5200 probe has two operating ranges that you select with the
ATTENUATION button on the front panel:
Select the 50X range for inputs of 0 V to 130 V (DC + peak AC).
Select the 500X range for inputs of 130 V to 1300 V
(DC + peak AC).
Both ranges are rated for the maximum input limits, but you can obtain a
useful measurement only if the voltage you apply is within the specified
limits of the operating range.
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.
Common-mode voltage greater than 1,000 VRMS can distort the output
signal, but the probe will not indicate an overrange condition.
Common-Mode Rejection
The common-mode rejection ratio (CMRR) is the specified ability of
P5200 High Voltage Differential 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 ability
of probe to reject common-mode signals. For exact specifications, see
the Specifications section. (See Table 3 on page 16.)
Common mode rejection decreases as the input frequency increases.
The following Figure is a plot of typical CMRR of the probe versus
input frequency. For example, if you apply a 60 Hz line voltage of
500 VP-P to both input leads of the probe, the probe rejects the signal by
80 dB (typical) and the signal appears as only a 50 mVP-P signal on the
oscilloscope screen.

Operating Basics
Figure 2: Input impedance vs. frequency
To maximize the rejection of common-mode signals, twist the input
leads together and do not use the extension leads. (See Figure 3.)
Twisting the Input Leads
Twisting the input leads helps to cancel noise that is induced into the
input leads, and to improve the high frequency response of the inputs.
For the best response possible, do not use the extension leads.
P5200 Instruction Manual

Operating Basics
Figure 3: Twisting the input leads
Extension Leads
The extension leads allow you to reach widely spaced connection
points. Connect the extension leads to the input leads using the adapters
provided. Be sure to use both extension leads so that the input leads
are the same length.
The extension leads, however, do affect the high-frequency performance
of the probe. With longer lead length, differential noise induced into
the input leads is greater. Also, because of the added inductance of
the leads, voltage measurements at frequencies above approximately
10 MHz may not be as precise. The following figure shows the effect
on HF transient response with (left waveform) and without (right
waveform). (See Figure 4 on page 13.)
The extension leads do not affect the performance of the probe when
bandwidth is set to 5 MHz.

Probe Loading
When you touch your probe tip to a circuit element, you are introducing
a new resistance, capacitance, and inductance into the circuit.
Frequency and impedance of the source determine how much the probe
loads the circuit that you are measuring. As 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.
The probe has virtually no loading effect on sources with relatively
low impedance and low frequency.

Specifications
The specifications in the following tables apply to a P5200 High Voltage
Differential Probe installed on a Tektronix TDS460A oscilloscope.
When the probe is used with another oscilloscope, the oscilloscope must
have an input impedance 1 M Ω an input capacitance range of between
15 and 20 pF, and a bandwidth not less than 100 MHz.
The probe must have a warm-up period of at least 20 minutes and be in
an environment that does not exceed the limits. (See Table 2.)
Specifications for the P5200 probe fall into three categories: warranty,
typical, and nominal characteristics.
WARNING. Special fixtures are required to examine specifications at the
maximum frequency and voltage levels and should be conducted only by
qualified Service Personnel. See the Service section for more details.
