Operator’s Guide/Tech Ref Manual

See

Figure 3-463 on page 3-161

for the Modulator Settings

Menu Map.

Modulator Data Channel interface parameters and settings are
dependent upon factory settings and hardware configurations.
The following Data Channel interface factory setting options are
available and must be specified when your SCM4000 is ordered:

Off

E3 1

E1 2

ASI 1

E3 2

Eth 1

ASI 2

SMPTE

Eth 2

ASI 3

T1 1

RS232

DS3 1

T1 2

RS485

DS3 2

E1 1

A maximum of four Modulator Data Channel interface options
can be configured by the factory. The Data Channel interface
options can consist of any combination of the factory setting
options. The configured system will depend upon the actual
radio system and the Data Channel interfaces desired.

Note

ASI 2, DS3 2, and E3 2 Data Channel interfaces
are not available in the SCM4000 Modulator/
Encoder configuration.

Data Channel interface options can consist of,

but are not

limited to

, some of the following examples, based on your

particular requirements.

•

Three ASI channels and one T1/E1 channel

•

One ASI Channel, one DS3/E3 channel, and two T1/E1
channels.

•

Two ASI channels, one T1/E1 channel, and one Eth
(Ethernet) channel

•

Two ASI channels and two T1/E1 channels

•

Two ASI channels, one SMPTE channel, and one T1/E1
channel.

Note

Main Screen menus for SCM4000 configurations
containing the Modulator option vary according to
hardware options installed in the unit.

”Overview” on page 3-12

to view the Main Screens

for all configurations of the SCM4000.

Modulator options for each configuration of the
SCM4000 are identical, therefore the Main
Screens shown in the following procedures are
typical.

Monitor/Change Symbol Rate

The procedure required to monitor and/or change the Symbol
Rate (SR) is contained in the following steps. The SR value
range is from 1.0 to 20.2 MS/s. Refer to the

Calculations” Appendix on page C-1

to determine bit rate vs.

symbol rate vs. QPSK, 16QAM, 32QAM, and 64QAM modulation
rates and bandwidth.

1.

Verify the SCM4000 is powered up.

2.

Verify the Main Screen is displayed.

See Figure 3-24

If the Main Screen is not displayed, press the

ESC

key

repeatedly until the Main Screen is displayed.
