Model SLN2006A 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 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 GLI2, CSM and LPA debug serial
ports.
25 pin D to 25 pin D serial cable from PC to 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 analyzers are currently supported
by the LMF:
HP8921A/600 Analyzer – Including 83203B CDMA Interface,
manual control system card, and 83236A/B PCS Interface for 1900 MHz
BTSs.
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 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.
