2.5.1
Cooling Considerations
The 2500B has an internal cooling fan. The air intake is located on the rear panel of the instrument. When placing or
installing the instrument for use, ensure there are no obstructions to the flow of air into the instrument, nor obstruction
for exhaust air flow at either side of the instrument.

AC Power Requirements
Table 3 below describes the power requirements and internal fuse specifications for the 2500B.
AC Line Cord:
All 2500B microwave signal generators are supplied with a 6-foot, three-wire power cord with three-
terminal polarized plug with a safety ground. If a different power cord is used, it must not exceed 3 meters (9 feet) in
order to meet safety requirements.
