Uplink Trigger Delay
[:SOURce]:RADio:WCDMa[:BBG]:ULINK:TRIGger:DELAy <value>
[:SOURce]:RADio:WCDMa[:BBG]:ULINK:TRIGger:DELAy?
Execute this command to change the propagation delay timing between the trigger from
the base station and the RF output of the signal generator. For additional information, see
“Understanding Time Offsets”on page3-8.
Range:
−50 to204 chips
Status after *RST: 0 chips
W Bits
Execute this command to set the value of the Perch1 W bits.
[:SOURce]:RADio:WCDMa[:BBG]:DLINK:PERCh[1]:WBITs <value>
[:SOURce]:RADio:WCDMa[:BBG]:DLINK:PERCh[1]:WBITs?
Range:0 to3
Status after *RST: 0
W-CDMA Operating State
[:SOURce]:RADio:WCDMa[:BBG][:STATe] ON|OFF|1|0
[:SOURce]:RADio:WCDMa[:BBG][:STATe]?
Execute this command to enable Option H98 wideband CDMA functionality. Activating
the feature sets up 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 andI/Q annunciators appear on the display when the
W-CDMA operating state is enabled.
In addition to theW-CDMA mode being enabled, the individual channels must be enabled
before each channel is output. If none of these channel are enabled, the output is an
unmodulated carrier.
Choices:
ON (1) orOFF (0)
Status after *RST: Off
