Measuring RF Loopback BER with Option 300
Connecting the Test Equipment
Refer to Figure 6-2 for connections to the ESG, VSA, and base station.
CAUTION If the base station output power is to be greater than the VSA input power
specification (+30 dBm), an external attenuator needs to be inserted prior to
the RF INPUT connector on the VSA.
Figure 6-2 BTS Loopback Test Equipment Setup
NOTE This example uses an ARFCN of 124 for the BCH and synchronizes to the TCH
midamble in timeslot 2 on ARFCN 124. You can substitute as appropriate for
your BTS.
All key presses assume factory defined defaults at preset.
