EVAP/Catalyst Systems not ready

I have a 2001 F-150 5.4 SC that won't pass emission testing because the EVAP and Catalyst systems are not ready. Obviously the testing facility told me to drive it more, but I have probaly drove 500 miles since then and it still is not ready. When I scan the vehicle with my AutoXRAY EZ-Scan 6000 I get the following information under the test results of the systems.

OBDMID $11 Fail
Test ID $01
0000 NOT>=0200
0000 <=FFFF
HO2S11 - Voltage Amplitude - Bank 1 - Sensor 1

I was guessing this was a faulty O2 sensor, but I have since replaced the sensor, cleared PCM and it still scans the same code.

Can anyone maybe explain this description in more detail to me to help me understand what I am missing.

Thanks - Jeff

You already got the answer.
Use a standard reader or scanner to get the codes in regular decimal form.
Your using a computer program beyond your ability to read it at the moment.
