TX and RX Testing
The following individual A TP tests can be used to evaluate specific aspects of UBS operation
against individual performance requirements. All testing is performed using the LMF GUI
environment.
TX Testing
TX tests verify transmit antenna paths and output power control. All tests are performed using
the external, calibrated test equipment. All measurements are made at the appropriate UBS
TX OUT connector(s).
TX tests verify TX operation of the entire CDMA forward link using selected sector -carriers
assigned to respective sector antennas. Each sector -carrier is keyed up to generate a CDMA
carrier (using BLO) at the NEC file -specified carrier output power level.
RX Testing
RX testing verifies receive antenna paths for the sector -carriers selected for the test. All tests
are performed using the external, calibrated test equipment to inject a CDMA RF carrier with
all zero long code at the specified RX frequency at the appropriate UBS RX IN connector(s).
RX tests verify RX operation of the entire CDMA reverse link.
Individual Tests
Standard P attern (per the 3GPP2 standard) - F or UBS Macro, the standard pattern is
the total digital gain of the signal (383) that includes the following channels (9 in all) and
their individual digital gain:
• Pilot -171
• P age - 165
• Sync - 83
• 6xTCH - 117
In the UBS Macro, the pilot is set to 36dBm, which brings the total power of this pattern to
43dBm - 7dB higher .
Spectral Purity TX Mask
This test verifies that the transmitted CDMA carrier waveform generated on each sector meets
the transmit spectral mask specification with respect to the assigned NEC file values.
