Getting Started
This section describes the High Voltage Differential Probe and gives
instructions on how to install and functionally test the probe.
Features and Accessories
The P5205 probe shown in Figure 1 provides a safe means of
measuring circuits with floating high voltages. The probe outputs a
low-voltage, ground-referenced signal for display on instruments
with the TEKPROBE interface (or any oscilloscope or other
measurem ent instrument when used with the Tektronix 1103
TEKPROBE power supply).
To protect you from RF and high voltage, the case of the probe is
nonconductive, internally shielde d, and isola ted. The internal shield
connect s t o earth ground through the output l ead. The case of the
probe and control buttons are isolated and double insulated. Thi s
protection extends up to the full input rating of the probe.
The accessories supplied with the probe meet the same safety
standards as t he probe. You may use other acc essories if they are
approved for the maximum voltage present in your application and
have the same style and size connectors.
The P5205 probe allows clear and accurate measurements of
high-speed transitions and provides excel lent rejection of common-
mode signals. B oth inputs have high impedance and low capaci tance.
Because of these features, the probe can safely measure the fast
voltage tra nsients in switching power devices without damaging
them.
Other applications for the P5205 probe include testing high-volt age
motor control circuits and line-connected circuits in switch-mode
power supplies.
