The Wideband Source for my 4808 appeared not to be working as the 4808 said
"Error 9" when I tried to use it.
While trying to work out what was wrong I checked the signals on the 15 pin
cable between the 4808 and the Option 70 box.
The signal on pin 9 was noticeable by its absence at the far end of the
cable (this is IDIGBUSON_H which should be +5V). It tells the Opt. 70 box
at the far end that the 4800 that's powered on.
Once I replaced the cable the beast woke up but only produces output for
0.34MHz and above. It is silent at lower frequencies.
Anyone have any ideas?
