Preset Descriptions
Description
The test set is capable of accepting several different preset commands.
At no time during a preset operation, does transmit power exceed the last user setting of the transmit power.
The input power is not set to any value lower than the last user setting of the input power. This is to avoid
power spikes on the output and possible receiver damage on the input during transitions associated with
preset operations.
Partial Preset
Partial preset saves setup time because measurement setup parameters remain unchanged. This is the
recommended way to place the test set in a known condition.
When you fast switch between formats in a fast switching test application the test set behaves as if a partial
preset has occurred. The table below lists some key partial preset results.
Example
OUTPUT 714;”SYSTEM:PRESET3” !Command for a partial preset when user in
!remote operation.
SYSTEM:PRESET3 is the recommended command for a partial preset operation. The SYSTEM:PRESET[1]
command is not recommended for use at this time.
Press the green Preset key on the front panel to perform a partial preset.
