Advantest R3465 Analyzer – Including R3561L Test Source Unit

HP8935 Analyzer

CyberTest Communication Analyzer

GPIB Cables

 Hewlett Packard 10833A or equivalent; 1 to 2 meters (3 to 6 feet) long

used to interconnect test equipment and LMF terminal.

Power Meter

 Hewlett Packard Model HP HP437B with HP8481A power sensor

 Gigatronix model 8541C

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.

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.
