The power supply CVR460 is a switching AC to DC converter. It automatically
detects the line voltage over the range of 90 to 264 VAC. It supplies power to all
the circuitry in the instrument. No switch completely disconnects the line power
from the instrument. The ON/STBY switch controls the power to the instrument
through the μATX board circuitry. When in the “power off” condition, there is still
a low power standby current to allow the system to monitor the ON/STBY switch.
Three fans on the side of the instrument provide forced air cooling. The fans are
controlled by the fan speed control circuit on the PWR board and are regulated by
monitoring the temperature at the circuitry.

personnel should perform adjustment procedures. Read the Service Safety
Summary and the General Safety Summary before p erforming any service
procedures.
Adjustment Interval
Adjustment After Repair
NOTE. Befor
e performing adjustment procedures, you must warm up the arbitrary
waveform generator at least 20 minutes in an ambient temperature between 20 °C
and 30 °C. Adjustments performed before warm-up or outside this temperature
range may result in poor performance.
If the instrument fails performance tests (refer to the AWG7000 Series Arbitrary
Wav e for
m Generators Technical Reference Manual), adjustment may be required.
If periodic calibration is one of your requirements, a general rule is to verify
mance and make adjustments (if needed) every 2000 hours of operation (or
perfor
once a y ear if the instrument is used infrequently).
After removal and replacement of a module due to electrical failure, you must
perform the adjustment procedure if the module you replaced is marked “yes”

Inspection and Cleaning
procedures
The collection
of dirt on internal components can cause them to overheat and fail.
Dirt also provides an electrical conduction path that could cause an instrument
failure, especially under high-humidity conditions. Inspect the instrument as
often as operating conditions require.
WAR N ING. Before performing any of the following procedures, power down the
instrument and disconnect it from line voltage.
CAUTION. Avoid the use of chemical cleaning agents, which might damage the
plastics used in this instrument. Use only deionized water when cleaning the
front-pa
nel buttons. Use an ethyl alcohol solution as a cleaner and rinse with
deionized water.
Inspection – Exterior. Inspect the outside of the instrument for damage, wear, and
missing parts, using the following table as a guide. An instrument that appears to
have been dropped or otherwise abused should be checked thoroughly to verify

Instrument Diagnostics
Troubleshooting
The primary diagnostics for the instrument are accessible through the AWG
application software. The Instrument diagnostics check the basic functionality
of analog and marker output at every power on. The Instrument Diagnostics run
after Windows has booted up and run its own set of system checks. If any failures
occur at pow
provides an error code:
Diagnostics error codes (See Table 8 on page 86.)
Calibration error codes (See Table 9 on page 92.)
Hardware error codes (See Table 10 on page 101.)
The power-on tests ensure that the hardware is installed and can be accessed
by the software. The tests provide limited diagnostic information, and provide
no performance information.
To run the instrument Diagnostics manually, do these steps:
1. Turn off all other applications.
er on, a pop-up message indicates that a failure has occurred and
2. From the menu bar, select System andthenselectDiagnostics...;the
Diagnostics dialog box appears. (See Figure 42.)
