P5200 Instruction Manual ix

Compliance Information
x 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 1

Features and Accessories
Figure 1: P5200 High Voltage Differential Probe
2 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.
P5200 Instruction Manual 3

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 reach. 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 plug 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 accompanies the
P5200 probe is the only adapter specified for this
probe. Using any other adapter voids the product
warranty and may also produce electromagnetic
interference. Adapters for the line voltages of
other countries are also available. Refer to the
Replaceable Parts section. (See page 29.)
