The maximum input voltage of 20 kV (DC + pea k AC) is derated at
frequencies above 460 kHz (See Figure 1--4 on pa ge 1--12).
The maximum peak pulse of 40 kV (which must never exceed
20 kV
rms
) is derated under the following conditions:
H Duty cycles greater than 10% or durations longer than 100 ms
(Figure 1--5). Duty cycle is the ratio of pulse width to signal
period, expressed as a percentage.
H Altitudes higher than 8000 fe et (2440 m). See ta bles 1--3 and
1--4.
H Relative humidity greater than 80% at 25° C, 70% at 35° C, or
30% at 50° C. See Tables 1--3 and 1--4.
H For voltages above Long Duration Line of Figure 1--5 on
page 1 --13, the time exposure is limited per Table 1--1 in any
2.5 hour period.
CAUTION. The ground le ad is rated at 1 kV maximum. Mak e sure the
ground lead does not contact the probe tip or a high-voltage point on
the circuit under test.
NOTE. This probe is designed to take voltage measurements between
1.5 kV and 20 kV (DC + peak AC) and impulses up to 40 kV peak .
For taking voltage measurements below 1.5 kV, Tektronix makes a
variety of probes specifically for these applic ations.
