Adjustment
Procedures
All adjustments are performed with the POWER ON. The side
covers should be removed to allow access to test points and
adjustments.
WARNING
Special care should be taken to prevent contact
with live circuits or the power line area. This could
cause an electrical shock resulting in serious
injury or death. Use an isolated tool when making
adjustments.
When necessary, refer to the component layouts
for determining adjustment points. Follow the
procedure in the sequence indicated as some
adjustments are interrelated and dependent on the
proceeding steps.
Verify that the waveform generator is functioning
according to the performance checks. Ensure that
all results are within or close to the range of the
required specifications; otherwise, refer to the
troubleshooting procedures given later in this
section.
Perform the following adjustment procedure. If an
adjustment cannot be made to obtain a specific
result, refer to the troubleshooting procedures.
NOTE
If not otherwise specified, configure the instrument
to factory defaults before each adjustment by
sending the *RST command. Always connect the
output BNC connector through a 50
Ω
feedthrough
termination.
