Enable HSPA analysis (W-CDMA(3GPP)/HSPA)
Cleared (See W-CDMA(3GPP) Standard Setups/
Presets Table.)
Enable HSPA Analysis enables/disables the HSPA "High Speed Packet Access" features of 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. See also IS-95.(3GPP)/HSPA modulation analysis. When Enable HSPA Analysis is cleared, the VSA measures standard W-CDMA signals. When Enable HSPA analysis is selected the VSA measures W-CDMA signals with HSPA channels.

Cleared |
Standard W-CDMA modulation analysis. HSPA channel analysis is turned off; HSPAchannels will not be measured correctly. |
1) Some Parameter adjustments are only available when is selected.
2) When HSPA analysis mode is selected, non-HSPA channels may not be measured correctly.
