Features and Accessories

The P5200 High Voltage Differential Probe provides a safe means of
measuring circuits with floating potentials up to 1,000 V
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 t he input BN C 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 m easurements of high-speed
transitions and pro vid e s 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 with out damaging these devices.

Other ap plications for the P5200 probe include testing hig h-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), su ch as the Tektronix TPS2000 series oscilloscopes and
THS700 series oscillosco pes. The P5200 High Voltage Differential Probe
requires an oscilloscope or other measurement instrument with a grounded
input.

Features and A ccessories

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 re present the signal on the probe input.

Range Button. In the raised position the
range button s ets the attenu ation 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 V

CAT II common mode.

RMS

Scale Conversion Chart. The chart lists the
effective volts per division for the 1/500 and 1/50
range settings a nd scale factors of 2 mV to 1 V on
the measurement instrument.

The effective volts per division is the a ttenua tion
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 V

ground and a maximum difference of 1,300 V
(DC + peak AC) between the inputs. T hese input
ratings are valid for both range settings.

Features and Accessories

Input Leads. The input leads of the differential
probe connect to the crocodile clips and plunger
probes that come with the probe. The connectors
are double insulated for safety.

NOTE. Use only the accessories provided with

the P5200 probe.

Plunger Probes. The plunger probes have long
probe sleeves with retracting hooks. These
probes connect safely to recessed test points that
are otherwise difficult to reac h. The connectors
are double insulated for safety.

Crocodile Clips. The large insulated clips
connect easily to large bolts or bus bars. The
connectors are double insulated for safety.

Output Lead. The BNC output connection to
the oscilloscope is calibrated to drive a high
impedance (1 MΩ) load.

Adapter Jack. The power supply jack on the
probe output connects to the 9 VDC p lug of the
AC adapter.

AC Adapter. The adapter converts AC line
voltage to 9 VDC for the probe power supply.

NOTE. The AC adapter that accompa nies the

P5200 probe is the only adapter specified for this
probe. Using any other adapter voids the product
warranty and may also produce electroma gnetic
interference. Adapters for the line voltages of
other countries are also available. Refer to the

electrical equipment are worth repeating here.

Observe the safety in stru ctio n symbols for t he equipment you are

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

risk of radio frequency (RF) burns.

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 t he performance of
the probe.

Operating L imits

The P5200 probe has two operating ranges that you select with the
ATTENUATION button on the front panel:

Select the 50X range for inputs o f 0 V to 130 V (DC + peak AC).

Select the 500X range fo r 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 ran ge 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 V

can distort the output

RMS

signal, but the probe will not indicate an overrange condition.

Common-Mode Rejection

The comm on-mode rejection ratio (CMRR) is the specified ability of
P5200 High Voltage Differential Probe to reject signals th at are common
to both inputs. More precisely, C MRR is t he 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 V
80 dB (typical) and the signal appears as only a 50 mV

Operating Basics

Figure 2: Input impedance vs. frequency

To ma xim ize 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 t o improve the high frequency response o f the inputs.
For the best response possible, do not use the exten sion leads.

P5200 Instruction Manual 11

Operating Basics

Figure 3: Twisting the inp ut 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 withou t (righ t
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.

Specifications

The specifications in the follo

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

The probe must have a warm-u

an environment that does not exceed the limits. (See Table 2.)

Specifications for the P

WARNING. These procedures require the application of high voltage to

the inputs of the P5200 probe. Because this adapter has exposed metal
surfaces, only qualified personnel should perform any testing with voltage
levels exceeding 30 V rms. All pertinent safety rules and guidelines for
elevated voltage measurements should be followed and adhered to.
