Specifications
The characteristics listed in Table 2 apply to a P6139A probe installed on a
Tektronix TDS 3054 oscilloscope unless otherwise noted.
Specifications apply when the instrument warms up for a period of at least
20 minutes in an environment that does not exceed the limits described in
Table 3 on page 4.
