PTO Acceptance Test
This test verifies the transmitted Pilot channel element Pilot Time Offset of each sector -carrier
keyed up at a specific frequency per the current NEC file assignment . All tests are performed
using the external calibrated test set controlled by the same command. All measurements
are via the appropriate TX OUT connector .
The Pilot Gain is set to 171 LSB for each antenna. The sector -carrier is enabled, using both
rfLvl and bay level offsets, to generate a CDMA carrier (with pilot channel element only , W alsh
code 0). Sector -carrier power output is set to 36 dBm as measured at the TX OUT connector
(on the UBS directional coupler).
The calibrated communications test set measures and returns the Pilot Time Offset in us,
verifying results meet system tolerances:
• Pilot Time Offset should be within +/– 3 us of the target PT Offset (0 us).
