Entering the Channel Power Measurement Bandwidth and Time

---

When performing a channel power measurement, you must specify a measurement bandwidth and measurement time. These parameters determine how the analyzer measures each channel on the Channel Scanner. Depending on the modulation format of signal you are trying to measure (CDMA, GSM, and so forth), different measurement bandwidths and times are required. You have three ways of selecting these parameters:

• Press [Format/BW], then on [Format Type] select List, and then select the format from a list-independently of the channel standard.
• Select [Format/BW], then on [Format Type] select Cust. Then select the measurement bandwidth and measurement time for each channel.

To Select the Channel Format Type:

	Step	Notes
1	[Format/BW]
2	On [Format Type] select Chan.	Each time you press this softkey, the selected option changes. The option you select determines which buttons on the right are active. Each channel standard has an associated modulation format. With this method, the optimum measurement bandwidth and measurement time for the modulation format are automatically selected when you set the channel standard. For example, when you select GSM-950 as the channel standard, with this method the test set selects the bandwidth and time for the GSM format.
3	Select the standard you want. [CS Chan Std] Select the standard using the up and down arrow buttons. [Select]

To Select the List Format Type:

1	Step	Notes
2	[Format/BW]
3	On [Format Type] select List.	Each time you press this softkey, the selected option changes. The option you select determines which buttons on the right are active.
4	Select the format you want. [Format List] Select the standard using the up and down arrow buttons. [Select]	This selection is independently of the channel standard selected under [Freq/Chan], [CS Chan Std].

To Select the Custom Format Type:

	Step	Notes
1	[Format/BW]
2	On [Format Type] select Cust.	Each time you press this softkey, the selected option changes. Each channel standard has an associated modulation format. With this method, the optimum measurement bandwidth and measurement time for the modulation format are automatically selected when you set the channel standard. For example, when you select GSM-950 as the channel standard, with this method the test set selects the bandwidth and time for the GSM format.
4	Set the channel power measurement bandwidth and measurement time. [Meas BW] Enter the bandwidth on the numeric keypad. [GHz] or [MHz] or [kHz] or [Hz] [Meas Time] Enter the time on the numeric keypad. [ms]
