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 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.
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.
