There are several electrical, mechanical, warranty, and documentation
options available for the CW Generator.
Electrical Options
There are four electrical options available for the CW Generator. These
options are as follows:
If Option 1E1 is ordered, an internal step attenuator is included before the

(90 dB for 83711A/83712A) in 10 dB steps (0|110 dB for 11B/12B). The
correct amount of attenuation is selected automatically by the CW Generator
dependent on the output power level selected. If this option is installed,
you can select whether or not the step attenuator will automatically switch.
This function is useful during certain applications, such as when external
automatic level control is used.

accuracy and stability. If Option 1E5 is installed, the CW Generator must be
connected to AC mains power to keep the reference oscillator at operating
temperature. If the reference oscillator has not been connected to mains
power (the oven is cold), the CW Generator requires 30 minutes to warm up.
