generator is in the uplink mode, it must be frequency-locked to the base
station receiver using the uplink trigger feature. Refer to“System

Long Code
Press this softkey to enter the long code for the uplink channels.
In multicode mode, all of the multicodes use the same long code. To
enter the long code value, rotate the front-panel knob until the desired
value is displayed, use the up and down arrow keys, or enter the value
using the numeric keypad and press the
Enter terminator softkey.
Long code value changes are not applied to the waveform until long
code reset, 1280 chips before the end of System Frame Number 2
16
−1.
Long code reset only occurs when:
•the W-CDMA operating state (
W-CDMA Off On) is toggled,
•the transmission link direction (
Link Down Up) is toggled,
•the internal System Frame Number transitions from SFN 2
16
−1 to
SFN 0,
•or when externally triggered by a BTS reference SFN reset input (a
low to high transition at the PATTERN TRIG IN rear-panel
connector).
Other setup changes in uplink mode, such as short code, data rate,
channel type, or time offset, do not affect the long code or long code
phase.
