Test Equipment Set-up
Connecting Test Equipment to the BTS
All test equipment is controlled by the LMF via an IEEE-488/GPIB bus.
If there is a communications problem between the LMF and any piece of
test equipment, verify that the GPIB addresses have been set correctly
(normally 1 for a signal generator, 13 for a power meter, and 18 for a
CDMA analyzer). See Appendix J for procedures to verify and change
the GPIB addresses.
The following equipment is required to perform optimization:
 LMF
 Test set
 Directional coupler and attenuator
 RF cables and connectors
 Null modem cable (see Figure 3-8)
 GPIB interface box
Refer to Table 3-22 and Table 3-23 for an overview of connections for
test equipment currently supported by the LMF. In addition, see the
following figures:
 Figure 3-12 and Figure 3-13 show the test set connections for TX
calibration.
 Figure 3-14 and Figure 3-15 show test set connections for IS-95 A/B
optimization/ATP tests.
 Figure 3-16 shows test set connections for IS-95 A/B and
CDMA 2000 optimization/ATP tests.
 Figure 3-17 and Figure 3-18 show typical TX and RX ATP setup with
a directional coupler (shown with and without RFDS).
Supported Test Sets
CAUTION
To prevent damage to the test equipment, all TX test connections
must be through the directional coupler and in-line attenuator as
shown in the test setup illustrations.
IS-95 A/B Testing
Optimization and ATP testing for IS-95A/B may be performed using
one of the following test sets:
 CyberTest
 Advantest R3465 and HP 437B or Gigatronics Power Meter
 Hewlett-Packard HP 8935
 Hewlett-Packard HP 8921 (W/CDMA and PCS Interface for
1.7/1.9 GHz) and HP 437B or Gigatronics Power Meter
The equipment listed above cannot be used for CDMA 2000 testing.
