Power Meter
One of the following power meters is required for TX calibration and
audit if an HP8921A or Advantest R3465 analyzer is used:
 Hewlett Packard Model HP HP437B with HP8481A power sensor
 Gigatronix model 8541C with model 80601A power sensor
Timing Reference Cables
 Two BNC-male to BNC-male RG316 cables; 3 meters (10 ft.) long,
used to interconnect the HP8921A/600 or Advantest R3465
communications analyzer to the CSM front panel timing references in
the BTS.
NOTE
Two Huber & Suhner 16MCX/11BNC/K02252D or equivalent;
right angle MCX-male to standard BNC-male RG316 cables;
3m long are required to interconnect the HP8921A/600
communications analyzer to SGLN4132A and SGLN1145A
CSM board timing references.
 BNC “T” adapter with 50 ohm termination.
NOTE
This BNC “T” adapter (with 50 ohm termination) is required to
connect between the HP 8921A/600 (or Advantest R3465)
EVEN SECOND/SYNC IN and the BNC cable. The BNC cable
leads to the 2-second clock connection on the TIB. Erroneous
test results may occur if the “T” adapter with the 50 ohm
termination is not connected.
Digital Multimeter
 Fluke model 8062A with Y8134 test lead kit or equivalent; used for
precision DC and AC measurements, requiring 4-1/2 digits.
Directional Coupler
 Narda model 30661 30 dB (Motorola part no. 58D09732W01) coupler
terminated with two Narda Model 375BN-M loads, or equivalent.
RF Attenuators
 20 dB fixed attenuators, 20 W (Narda 768-20); used with test cable
calibrations or during general troubleshooting procedures.
 Narda Model 30445 30 dB (Motorola Part No. 58D09643T01) coupler
terminated with two Narda Model 375BN-M loads, or equivalent.
Miscellaneous RF Adapters, Loads, etc
 As required to interface test cables and BTS equipment and for
various test set ups. Should include at least two 50 Ohm loads (type
N) for calibration and one RF short, two N-type female-to-female
adapters.
High-impedance Conductive Wrist Strap
 Motorola model 42-80385A59; used to prevent damage from
Electrostatic Discharge (ESD) when handling or working with
modules.
RF Load (at least three for trunked cabinets)
 100 W non-radiating RF load; used (as required) to provide dummy
RF loading during BTS transmit tests.
