There are Eve electrical options available for the sweeper. These options are
as follows:
If Option is ordered, an internal step attenuator is included before the
RF OUTPUT connector. The step attenuator has a range of 0 to 70 in 10
steps. The correct amount of attenuation is selected automatically by
the sweeper dependent on the output power level selected. If this option is
installed, you can select whether or not the step attenuator will automatically
switch. (Refer to the “Special Functions” chapter, special function number 6.)
If Option is ordered, the RF OUTPUT connector will be moved to the rear
panel.
If Option is ordered, the sweeper is shipped with a 10 MHz
temperature-controlled crystal reference oscillator for increased frequency
accuracy and stability. When Option
is installed, the sweeper must
be connected to ac power to keep the reference oscillator at operating
temperature. If the reference oscillator has not been connected to ac power
(the oven is cold), the sweeper requires 30 minutes to warm up.
If Option is ordered, the RF OUTPUT connector is a ruggedized type-N
female connector instead of the standard 3.5 mm connector. When this option
is installed, output power characteristics above 18 are typical and not
warranted.
