Tektronix P5122 User manual

xx P5122 100X Probe
The P5122 Probe is a high voltage probe with 100X
attenuation and a compensation range of 10 to 25 pF.
The probe is designed for use with Tektronix TPS2000
and THS3000 series floating oscilloscopes with high
input impedance (1 M Ω). The probe has no user- or
Tektronix-serviceable parts.
WARNING. The reference contact ring (see below) is
always the same voltage as the reference lead. To avoid
arc flash, always ensure the insulation sleeve or hook
tip is installed to cover the reference contact ring.
Connecting the Probe to the Oscilloscope
Connect the probe as shown in the illustrations below.
Compensating the Probe
Due to variations in oscilloscope input characteristics,
the low-frequency compensation of the probe may need
adjustment after moving the probe from one oscilloscope
channel to another.
If a 1 kHz calibrated square wave displayed at 1 ms/division
shows significant differences between the leading and
trailing edges, perform the following steps to optimize
low-frequency compensation:
1. Connect the probe to the oscilloscope channel that you
plan to use for your measurements.
2. Connect the probe to the probe compensation output
terminals on the oscilloscope front panel.
WARNING. To avoid electric shock, only connect to the
Probe Comp signal on the oscilloscope when making
this adjustment.
3. Depress the locking pin inside the protective sleeve.
4. Turn the sleeve and the cable end until the adjustment
is visible through the opening.
5. Push AUTOSET or otherwise adjust your oscilloscope
to display a stable waveform.
6. Adjust the trimmer in the probe until you see a perfectly
flat-top square wave on the display. (See illustration.)
WARNING. To avoid electric shock, only use the
insulated adjustment tool when making compensation
adjustments.
7. Turn the sleeve back and lock the sleeve in place.
WARNING. To avoid electric shock, ensure that the
sleeve is locked in the closed position after making
compensation adjustments.
Connecting the Probe to the Circuit
Use the standard accessories included with the probe to
connect to your circuit. (See Table 1.)
WARNING. To avoid electric shock when using the probe
or accessories, keep fingers behind the finger guard of
probe body & accessories (as shown).
To reduce risk of shock, when using the probe on floating
measurements, ensure the reference lead accessories are
fully mated before connecting the probe to the circuit
under test.
Standard Accessories
The standard accessories included with the probe can be
reordered as a kit. The kit includes one of each item shown

Specifications
Read the caution below if you are using the probe with the
TPS2000 series oscilloscope input set to AC coupling.
CAUTION. When the oscilloscope input is set to AC
Coupling, do not probe DC levels >300 V or AC signals
less than 1 Hz and >300 VRMS. (See graph below.)
Refer to the reference lead derating curve below when
making floating measurements.

Safety Summary
Review the following safety precautions to avoid injury and
prevent damage to this product or any products connected
to it. To avoid potential hazards, use this product only as
specified. Using the probe or accessories in a manner not
specified could result in a shock or fire hazard.
To Avoid Fire or Personal Injury
For Use With TPS2000 and THS3000 Series Oscilloscopes
Only. Do not float the reference lead of this probe above the
rated float voltage (600 V RMS CAT II).
Connect and Disconnect Properly. Connect the probe output
to the measurement instrument before connecting the probe
to the circuit under test. Disconnect the probe input and
the probe reference lead from the circuit under test before
disconnecting the probe from the measurement instrument.
Avoid Electric Shock. To avoid injury or loss of life, do not
connect or disconnect probes or test leads while they are
connected to a voltage source.
Observe All Terminal Ratings. To avoid fire or shock hazard,
observe all ratings and markings on the product. Consult
the product manual for further ratings information before
making connections to the product.
Avoid Electric Shock. When using probe accessories, never
exceed the lowest rating of the probe or its accessory,
whichever is less, including the measurement category and
voltage rating.
Avoid Electric Overload. To avoid injury or fire hazard, do
not apply potential to any input, including the reference
inputs, that varies from ground by more than the maximum
rating for that input.
Avoid Exposed Circuitry and Do not Operate Without
Covers. Do not touch exposed connections and components
when power is present.
Inspect The Probe And Accessories. Before each use,
inspect probe and accessories for damage (cuts, tears,
defects in the probe body, accessories, cable jacket, etc.).
Do not use if damaged.
Do Not Operate in Wet/Damp Conditions.
Do Not Operate in an Explosive Atmosphere.
