The Min Ec lo specified in the table above is based on processing gain The weakest to strongest values were produced by computer simulation page 26 id Lt s lt Super Eagle Manual 2 2 It is not advisable for an Super Eagle user to attempt calibration by themselves This is because the HP 8924C is really a base station simulator and has a rather inaccurate power control limited to 30 dBm because it was not intended to accurately measure or control power just to simulate a high level radiated signal More importantly it would be an apples to oranges calibration since the HP and even the Tektronix Rodie base station simulators include all CDMA channels and not just Pilot as in the Super Eagle The Tektronix CDMA unit is much more accurate and extends 18 dB further but still not advisable The calibration process of an Super Eagle is rather tedious and extensive We are automating it here but it still is too complex to detail to customers It requires some hardware fixtures and can be treacherous because the calibration tables must be exact or the unit will be way off The process itself uses a Calibrated CDMA source right now an HP 4000A signal generator externally modulated or a Duet PN and fed into a series of automated step attenuators BVS provides free calibration to all of our Super Eagles customers that are within the warrantee period of 180 da
