P6131 Instruction Manual 3
Specifications
The characteristics listed in Table 1 apply to P6131 probes installed on Tektronix
2445 and 2465 oscilloscopes or 7A42 plug-ins, unless otherwise noted.
Specifications apply when the instruments warm up for a period of at least
20 minutes in an environment that does not exceed the limits described in
Table 2 on page 5.
