The measurement limits settings enable you to alter the values of the test limits for
the important measurements on the CDMA Tx Analyzer Screen. These settings
affect the metrics color display: red represents fail, green represents pass. Next to
the displayed measurement value, a (P) for Pass, or (F) for Fail, will be shown to
further indicate whether the value is within or outside the set limits. In addition, the
words “ALL PASS” or “FAILURE” are displayed in the bar at the bottom of the
screen for all limits which have been turned on.
• Frequency Error Limits: Sets the high and low Frequency Error limits for the
channel. Any measured frequency error that is outside of the set limits will result
in a failure indiction. The High limit is set by entering a positive number, and the
Low limit is set by entering a negative number.
• Time Offset Limits: Sets the high and low time offset limits for the channel.
Limits are set in microseconds. Any measured time offset value that is outside of
the set limits will result in a failure indication.
• Est. Rho Limit: Sets the lower Estimated Rho limit for the channel. Any
measured value of estimate Rho this is below the set limit will result in a failure
indication.
• Carrier Feedthrough Limit: Sets the upper carrier feedthrough limit for the
channel. The upper limit is set in dBc and is relative to channel power. Any
measured carrier feedthrough value that is above the set limit will result in a
failure indication.
• Noise Floor Limit: Sets the upper noise floor limits for the channel. The limit is
set in dB. Any measured noise floor value above the set limit will result in a
failure indication.
• Pilot Power Limit: Sets the upper and lower limits of the pilot power. These
