Source Enable ON OFF
— ON Turns ON the internal source.
— OFF Turns OFF the internal source.
Source Mode Choose from the following:
— Tracking The internal source frequency can track the SA receiver.
Center frequency
— CW The source is set to a CW frequency independent from the SA
settings. Srcw is annotated on the screen.
— Coupled CW The source is set to a CW frequency, but that frequency
"tracks" the SA receiver Center Frequency settings. Therefore, the

Source Power Sets the source power level. Choose from:
— Leveled Enter a value from -45 dBm to 0 dBm using the numeric
keypad, arrows, or the rotary knob
reasonably flat across the frequency span.
— MAX The power level is set to the maximum achievable power level at
each frequency. This results in the power level NOT being flat across
the frequency span.
Source CW Freq Sets the CW frequency that is used when Source Mode is
set to CW.
