female connector instead of the standard 3.5 mm connector. When this option
is installed, output power characteristics above 18 GHz are typical and not
warranted.
There are several options available for the sweeper. They are explained in
the following sections.
There are Eve electrical options available for the sweeper. These options are
as follows:
If Option 1El is ordered, an internal step attenuator is included before the
RF OUTPUT connector. The step attenuator has a range of 0 to 70 dB in 10
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 lE5 is ordered, the sweeper is shipped with a 10 MHz
temperature-controlled crystal reference oscillator for increased frequency
accuracy and stability. When Option lE5 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
