5.1.4.1.3 Spectrum Analyzer
The built-in spectrum analyzer mode is available, accessible via remote control, front panel
operation, or web browser. When it is active, the selected demod will not respond to specific Rx

menu controls under the
Test

TX TX | (right-hand display area)
<RX> RXS | (right-hand display area)
In this example, the receiver module installed in Slot#4 (bottom right on the VFD and when viewing
the rear panel of the chassis) is being used as a spectrum analyzer. Only one Rx is allowed to enable
spectrum analyzer in a chassis. To view the spectrum, the user needs to access the CDM-Qx Web
Server Interface via a web browser.
5.1.4.2 VFD – Right-Hand Display Area
The right-hand side display area (or menu screen) facilitates operation of the selected installed
device (module) or group (modules).
Note: To group a modulator and demodulator together requires a modulator module to be
installed above a demodulator module; one of the two modules then needs to be selected via the
left-hand display area. Returning to the right-hand display area, the user must select
Config Æ
Group Æ Modem , then select
Group
(see Sect. 5.7.1.4 for details).
5.2 Front Panel Operation – Opening Screen
The opening screen is displayed whenever
power is first supplied to the unit. On the
menu screen side of the display, the top line
identifies the unit in use (CDM-Qx for 70/140 MHz operation, CDM-QxL for L-Band operation).
The second line of the menu screen identifies the installed firmware version.
Note the following:
• V1.X.X ↑ = Original chassis (units typically manufactured prior to July 2008)
running Firmware No. FW/11245.
• V2.1.1 ↑ = Upgraded chassis (units typically manufactured from July 2008 to
present) running Firmware No. FW0000107.
Control of the selected module is determined by the selection made via the left-hand display (slot
screen). The slot screen can be accessed by using the ◄ arrow key if the menu-level is MAIN,
CONFIG, MONITOR, or INFO (and there is more than one installed module present for
selection).
Press any key to go to the Main Menu screen. Table 5-1 outlines the chapter sections and,
subsequently, the hierarchal structure of the front panel menu tree.
