4. Burst Sel	This field selects the burst that the measurement will synchronize to.
	Choices	0
		1
		2
		3
		Ext is used for selecting burst number 0, 1, 2, or 3 in real- time
		using the SYSTEM BUS (rear-panel connector) or using internal
		signals while Activated.
5. Burst Type	This field defines the burst type. Choose from eleven burst types, or User Def for
	specifying a user defined burst type.
	Choices	TSC0 through TSC7 (Training Sequence Codes) are used for
		normal bursts.
		RACH (Random Access Channel) is used for access bursts.
		SCH (Synchronization Channel) is used for synchronization
		bursts.
		FCH (Frequency Channel) is used for frequency correction bursts.
		User Def (User Defined) is used when your burst does not conform
		to any of the burst types listed (such as PRBS), or when measuring
		noisy signals.
	User defined burst lengths must be 87 or 147 (plus 4 guard bits), and the User
	Defined Sync Pattern can comprise part of or all of the bits in the burst.
	To measure a noisy signal (approx 10 deg rms), enter the entire burst in User
	Defined Sync Pattern, and use Midamble Expected (see Screens: DSP Analyzer:
	Data Bits or Phase Err). The ideal phase trajectory will be calculated from the User
	Defined Sync Pattern, eliminating the problem of extremely high peak phase error
	due to bit errors.
	User Def is not allowed for Digital Demod.
6. Burst Type	This field displays a summary of the Burst Type definitions for the four definable
	bursts.
7. Burst Used	This field displays which one of four possible burst types was used for
	synchronization or alignment during a measurement. Refer to the Burst Definition
	or Burst Def fields.
