Preparation for Use

 

To check the fuse￿ remove the fuse holder on the rear panel￿ Refer to Fig/

 

ure￿￿/￿ for the location of the fuse holder￿ To remove the fuse holder￿ turn it

 

counter/clockwise with a screwdriver while pushing it in￿ Then remove the

 

fuse from the fuse holder￿

￿pplying and

Consider the following information when you power on or power off the

Interrupting Power

AWG￿￿￿5 or when external power loss occurs￿

 

 

Power on Cycle

 

At power/on￿ the start/up diagnostics check the AWG￿￿￿5 operation￿ The

 

start/up diagnostics take about 3￿ seconds￿ If all diagnostic items complete

 

without error￿ the AWG￿￿￿5 displays PASS on the screen and then changes

 

to the SETUP menu￿

 

If the diagnostics detect an error￿ the AWG￿￿￿5 displays FAIL and the error

 

code￿ To exit the diagnostics menu￿ press any key; then the system displays

 

the SETUP menu￿ See section 6￿ Maintenance￿ for information on diagnos/

 

tics and fault isolation￿

 

NOTE

 

If the ambient temperature goes outside the specified operating

 

temperature range, an error occurs during the diagnostics at pow(

 

er(on. If this happens, power off the AWG2005 and wait until the

 

chassis temperature is appropriate; then switch the power on

 

again.

 

Power off Cycle

 

CAUTION

 

To prevent loss of internally stored adjustment constants, DO NOT

 

power off the AWG2005 when doing the internal calibration de(

 

scribed in section 5, Adjustment Procedures.

 

Wait for the AWG￿￿￿5 to finish the operation when doing internal calibration

 

or saving waveform or sequence files￿ Improper power/off or unexpected

 

loss of power to the AWG￿￿￿5 can result in the corruption of data stored in

 

nonvolatile memory￿
