PRELIMINARY

Timing reference cables

S 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,

S Two BNC–male to BNC–male RG316 cables; 3 meters (10 feet) long,

used to interconnect the HP8921A/600 Communications Analyzer to

SGLN4132B and SGLN1145B (and later) CSM front panel timing

references in the RF Modem Frame.

Digital multimeter

Fluke Model 8062A with Y8134 test lead kit or equivalent; used for

precision DC and AC measurements to four decimal places.

Directional coupler

Narda Model 3020A 20 dB coupler terminated with two Narda Model

375BN–M loads, or equivalent.

RF attenuators

S 20 dB Fixed attenuator, 20 Watt (Narda 768–20), used in conjunction

with calibration of test cables or during general troubleshooting

procedures.

S 10 dB Fixed attenuator, 20 Watt (Narda 768–10), for cable calibration

with a Cybertest CDMA analyzer.

Miscellaneous RF adapters, loads, etc.

As required to interface test cables and BTS equipment and for various

test setups. Should include at least (2) 50 Ohm loads (type N) for

calibration and (1) RF short.

RF load

100W non–radiating RF load used (as required) to provide dummy RF

loading during BTS transmit tests.

High–impedance conductive wrist strap

Motorola Model 42–80385A59; used to prevent damage from ESD when

handling or working with modules.
