Bypass RRC Meas Filter (W-CDMA(3GPP)/HSPA)
Selected (See W-CDMA(3GPP) Standard Setups/Presets Table.)
disables , or bypasses, the VSA internal Root-Raised-Cosine (RRC) measurement filter. This feature allows the VSA to measure W-CDMA Code Division Multiple Access: One of several digital wireless transmission methods in which signals are encoded using a specific pseudo-random sequence, or code, to define a communication channel. A receiver, knowing the code, can use it to decode the received signal in the presence of other signals in the channel. This is one of several "spread spectrum" techniques, which allows multiple users to share the same radio frequency spectrum by assigning each active user an unique code. CDMA offers improved spectral efficiency over analog transmission in that it allows for greater frequency reuse. Other characteristics of CDMA systems reduce dropped calls, increase battery life and offer more secure transmission.
