Troubleshooting Setting Power Levels

Last updated: June 29, 2006

Before turning AWGN on, be sure cell power is not set to a level significantly below the AWGN level, or the connection may be dropped.

A power level may be within the settable range but cause an error message to be displayed. You should verify that:

• The difference between cell power and AWGN power must not be more than 35 dB when both powers are ON.
• The total RF power and amplitude offset must not set the source outside its valid hardware range.
• When the test set is configured to physical layer subtype 2 and both Cell power and AWGN power are On, the power level of any MAC code channel generated must not be greater than 30dB below the current Total RF Power:
  • When any cell or AWGN power level is changed such that any code channel is more than 30dB below the current Total RF Power, an error message is posted to indicate the error condition. When this happens, the cell or AWGN setting is pended (saved but not applied to the hardware) and the current power setting is not updated (remain at previous setting) until the error condition is removed. See Cell Power, AWGN (Additive White Gaussian Noise) Power and Total RF Power .
  • When any MAC code channel level is changed such that the code level is more than 30 dB below the current Total RF Power, an error message is posted to indicate the error condition. When this happens, the code channel level is rejected (remain at previous setting). See Code Channel Parameters .
