Quick Start Guide
Select Output Path
These selection buttons are used to select
between the IF OUT (Wide-BW) or IF AUX OUT as the IF output.
•
When IF OUT (Wide-BW) is selected, the IF input signal that is
applied to either IF A IN or IF B IN is directly delivered to the
IF OUT (Wide-BW).
•
When IF AUX OUT is selected, the IF input signal that is applied to
either IF A IN or IF B IN is used to deliver a narrow-band IF signal
output centered on 21.4 MHz out of the front panel. The input signal
at IF A IN or IF B IN must be centered at 249.4 MHz in order to
produce 21.4 MHz at IF AUX OUT.
Select IF AUX Bandwidth
These selection buttons are used to
select the switchable filter that is used when the Select Output Path is set
to IF AUX OUT.
•
When 30 kHz is selected, the IF AUX bandwidth is set to 30 kHz.
•
When 8 MHz is selected, the IF AUX bandwidth is set to 8 MHz.
