CAUTION Ventilation Requirements: When installing the product in a cabinet, the
convection into and out of the product must not be restricted. The ambient
temperature (outside the cabinet) must be less than the maximum operating
temperature of the product by 4° C for every 100 watts dissipated in the cabinet.
If the total power dissipated in the cabinet is greater than 800 watts, then forced
convection must be used.
Cooling holes are lo cat ed on t he sides and bottom of the instrument cover and the
rear panel of the instrument. Do not allow these holes to be obstructed as they
allow air flow through the signal generator.

Verifying Signal Generator Operation
Verifying Signal Generator Operation
The operator’s check is appropriate as a daily functional check by users, or
whenever the integrity of the signal generator is in question. Use the operator’s
check to verify prop er operation of the signal g enerator. The operator’ s check does
not ensure performanc e to specifications. To verify specific ations, refe r to the
calibration guide.
Operator’s Check
Perform the following tasks in order:
1. Power On the Signal Generator and Check for Error Messages
This procedure verifies that the signal generator powers up and that the internal
instrument check identifies no errors.
1. Turn power on to the signal generator by pressing the power switch. The green LED
will light. Let the instrument warm up for one hour.
2. Cycle the power to the signal generator. The green LED should again be lit and the
instrument will perform a check.
