Using the Spectrum Analyzer

To use the spectrum analyzer to check that your data looks ok, do the following:

Plug the spectrum analyzer into cable rach 4 IF output (3rd chassis from te top). On the spectrum analyzer, 1st, hit:

freq -> 750 -> MHz

then...

span -> 500 -> MHz

You will see a flipped spectrum. You can now move the cable to rack 6 IF output (pola B) and check that it looks the same. Appendix ??? has a description of the downstairs racks.
