DRAFT
Two Huber & Suhner 16MCX/11BNC/K02252D or
equivalent; right angle MCX–male to standard BNC–male
RG316 cables; 10 ft. long are required to interconnect the
HP8921A/600 communications analyzer to SGLN4132A
and SGLN1145A CSM board timing references.
NOTE
BNC “T” adapter with 50 ohm termination.
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.
NOTE
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.
