W-CDMA Off On
Press this softkey to enable Option H98 wideband CDMA functionality.
Activating the feature configures the internal hardware to generate the
structure defined by the W-CDMA experimental system specification. A
10 ms radio frame is constructed for each dedicated traffic channel
consisting of 16 timeslots which include pilot symbols, transmit power
control bits, ACCH fields filled with zeroes, and data fields filled with
selected data (zeros, PN9, or PN15). The
WCDMA and I/Q annunciators
appear in the display when this softkey is toggled on.
In addition to enabling the W-CDMA Off On softkey, you must enable at
least one of the individual channel softkeys (
Perch1 Off On, Perch2 Off On,
and
Channel State Off On) in order to wideband CDMA waveform output. If
none of these channel softkeys are enabled, the output is an
unmodulated carrier.
