2.12.5 Menu IS-95 CDMA Standard - Reverse Link Signal without
Channel Coding
Menu DIGITAL STD - IS-95 provides access to settings for IS-95 CDMA signal generation. The
following figure shows the menu for generating the reverse link signal (transmit signal of mobile station)
without signal coding. The previous section showed the menu for generating the forward link signals as
well as the parameters that are identical for both modes.

RATE
Selection of full-rate or half-rate transmission of modulation data. This
selection is only possible in the reverse link mode.
In the half-rate mode, only 8 of 16 power control groups of a frame are
transmitted ("power gating").
IEC/IEEE-bus command :SOUR:IS95:RATE HALF
BURST
RANDOMIZER
Switch on/off of burst randomizer. This selection is only possible during half-
rate transmission in the reverse link mode.
OFF Every second power control group is transmitted.
ON A random algorithm determines which eight of the 16 power
control groups of a frame will be transmitted.
