Preparation for Use
2-6 AWG510 & AWG520 Service Manual
Operating EnvironmentThe following environmental requirements are provided to ensure proper
operation and long instrument life.
Operate the waveform generator where the ambient air temperature is from
10_ C to +40_ C with no diskette in the floppy drive. Store the AWG500 in
ambient temperatures from –20_ C to +60_ C with no diskette in the floppy
drive. After storage at temperatures outside the operating limits, allow the chassis
to stabilize to a safe operating temperature before applying power.
The waveform generator is cooled by air drawn in and exhausted through the
cabinet side panels by an internal fan. To ensure proper cooling of the waveform
generator, allow at least 6 inches (15 cm) clearance on both sides, 0.8 inches (2
cm) on the bottom, and 3 inches (7.5 cm) on the rear of the AWG500. (The feet
on the bottom of the waveform generator provide the required clearance when set
on flat surfaces.)
When the air flow is restricted and the temperature of the DACmodule
surface goes over 80_ C, the AWG500 may temporarily shut down to protect the
internal modules. To prevent temporary shutdown of the AWG500, do not restrict
air flow through the chassis.
In firmware version 1.4 and later, the AWG500 displays the message “Power fail
or out of temperature limit” before shutting down.
If the AWG500 shuts down unexpectedly, improve ventilation around the
AWG500 and wait a few minutes to allow it to cool down; then switch the power
on again.
