DRAFT
Model SLN2006A Man Machine Interface (MMI) Interface Kit
Motorola Model TRN9666A null modem board. Connectors on
opposite sides of the board must be used as this performs a null
modem transformation between cables. This board can be used for
10–pin to 8–pin, 25–pin to 25–pin and 10–pin to 10–pin conversions.
Motorola 30–09786R01 MMI cable or equivalent; used to interface
the LMF serial port connection to Group Line Interface (GLI2), CSM
and LPA debug serial ports.
25–pin D to 25–pin D serial cable; used to interface the PC to the null
modem board.
Communications System Analyzer
The communication system analyzer is used during optimization and
testing of the RF communications portion of BTS equipment and
provides the following functions:
(1) Frequency counter
(2) RF power meter (average and code domain)
(3) RF Signal Generator (capable of CDMA modulation)
(4) Spectrum Analyzer
(5) CDMA Code Domain analyzer
Four types of Communication System Analyzer are currently supported
by the LMF. They are:
HP8921A/600 Analyzer – Including 83203B CDMA Interface,
manual control system card, and 83236A/B Personal communication
Interface (PCS) Interface for 1700/1900 MHz BTS.
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
One of the following power meters is required with the HP8921 and
Advantest analyzers:
Hewlett Packard Model HP HP437B with HP8481A power sensor
Gigatronics 8541C with model 80601A power sensor
Timing Reference Cables
Two BNC-male to BNC-male RG316 cables; 3.05 m (10 ft.) long.
Used to connect the communications analyzer to the front timing
reference of the CSM cards in the BTS frame.
Digital Multimeter
Fluke Model 8062A with Y8134 test lead kit or equivalent; used for
precision dc and ac measurements, requiring 4–1/2 digits.
