Tektronix P6015A

In Detail
P6015A Instruction Manual
1–11
The maximum input voltage of 20 kV (DC + peak AC) is derated at
frequencies above 460 kHz (See Figure 1–4 on page 1–13).
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 feet (2440 m). See tables 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 lead is rated at 1 kV maximum, unlike the
probe itself. Although the insulation capability of the lead is
considerably higher, be careful not to let the ground lead 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 applications.
