What do the LED’s in the front panel indicate?
The front panel outputs have frequency range limits at which their outputs are valid. The green LED’s indicate when a particular output is valid and usable. The CMOS and RF outputs are disabled outside of their operating ranges. The LVDS outputs are active below their respective lower operating limit (10MHz) in an under-scan mode. Operation of the LVDS outputs in under-scan mode cannot be guaranteed, and the LVDS LED is thus turned off.
