To set the active channel threshold level: Step NOTE Notes 1 [Setup] 2 On [Threshold] select Auto or Manual. Each time you press this softkey, the selected option changes. If you choose Manual, you must enter the threshold you want using the numeric keypad, then press [dB]. 3 [Auto Thres Offset] The default value is 0 dB. Optionally, you can enter a negative (more aggressive) or positive (more conservative) value, then press [dB]. Knowing which inactive code channels are contributing the most noise to the overall W-CDMA or W-CDMA (with HSDPA) channel may provide clues to the source of noise, such as a bad channel card in the base station. Setting Measurement Time The Measurement Time setting allows you to alter the speed at which measurements are being made. Three choices exist: Slow, Medium, and Fast. The test set defaults to Medium. Slow measurement time provides a more accurate measurement at the expense of time. Fast measurement time provides a quicker measurement at the expense of accuracy. Medium measurement time strikes a balance between measurement speed and measurement accuracy. Changes in measurement time, or measurement speed, are achieved by varying the amount of data used to plot the CDP trace, and by varying the type of frame alignment used.
