Preparation for Use

Operating Voltage The AWG710 Arbitrary Waveform Generator operates with any line voltage from

90 to 250 VACRMS with any line frequency from 48 to 63 Hz. There are two fuses, either of which may be used throughout the line voltage and frequency

ranges. The two fuses are not interchangeable as each requires a different fuse cap.

Memory Backup Power Memory modules with on-board batteries allow the AWG710 Arbitrary Waveform Generator to retain only internal clock data upon loss of the AC power source.

To set the date and time in the waveform generator, see the Reference:Internal Clock (Date and Time) section of the AWG710 Arbitrary Waveform Generator user manual.

Operating Environment

The following environmental requirements are provided to ensure proper operation and long instrument life.

Operating Temperature Operate the Waveform Generator where the ambient air temperature ranges from 10_ C to +40_ C (50_ F to +104_ F). Store the Waveform Generator at ambient temperatures from ±20_ C to +60_ C (±4_ F to +140_ F). After storage at temperatures outside the operating limits, allow the chassis to stabilize to a safe operating temperature before applying power.

Ventilation Requirements The Waveform Generator is cooled by air drawn in and then exhausted through the cabinet side panels by an internal fan. To ensure proper cooling of the Waveform Generator, allow at least 15 cm (6 in) clearance on both sides, 2.0 cm (0.8 in) on the top and bottom, and 7.5 cm (3 in) at the rear of the Waveform Generator. (The feet on the bottom of the Waveform Generator provide the required clearance when set on flat surfaces.)

￿￿UTION￿ When the air flow is restricted and the temperature of the DAC module surface exceeds 80_ C, the AWG710 Arbitrary Waveform Generator may temporarily shut down to protect the internal modules. To prevent temporary shutdown of the waveform generator, do not restrict air flow through the chassis.

The AWG710 Arbitrary Waveform Generator displays the message ªPower fail or out of temperature limitº before shutting down.

If the AWG710 Arbitrary Waveform Generator shuts down unexpectedly, create more ventilation around the waveform generator. Wait a few minutes to allow cool down and then switch the power on again.
