1.0 GENERAL INFORMATION 1.1 System Overview The MA4367 is a frequency-agile commercial quality transmitter for MMDS applications. Advanced design permits full frequency agility over the 2505 to 2681 MHz frequency band while still maintaining a phase noise specification which exceeds the requirement for 64 and 256QAM. The MA4367 is a Vecima 4000 series system which includes an upconverter, power amplifier and power supply/control module housed in a single chassis.

2.0 INSTALLATION CAUTION: This device must be professionally installed. 1 mW/CM2 is the maximum permissible exposure for radio transmitters between 1.5 to 100 GHz for uncontrolled environments. The installer of this radio equipment must ensure that the antenna is located or pointed such that it does not emit RF fields in excess of the FCC recommended limits. For more information, refer to the Federal Communications Commission guidelines on radio frequency safety, accessible through their Web site: www.fcc.
2.3 Power Requirements The equipment is supplied with either an AC international auto-ranging internal power supply which allows it to be powered from any 100 to 240 VAC; 50 to 60 Hz source, or a DC supply capable of operating from –36 to –60 VDC. Check the total current consumption of all equipment on the same line before applying power to the MA4367 system. Avoid sharing a power source that feeds heavy motors or other equipment, which require large current drains. 2.

3.2 Front Panel Operating Modes 3.2.1 MA4061B Upconverter Modes FREQUENCY When this mode is selected, the display will read: Frq XXXX.XXXX MHz The displayed frequency is the current configured Output Frequency. To adjust the output frequency, use the UP/DOWN buttons. Single stepping will allow 62.5 kHz adjustment, while holding the buttons depressed will change the frequency more quickly. ( ( The displayed frequency represents the center of the band.
OUTPUT ENABLE/DISABLE When this mode is selected, the display will read: Output Enabled or Output Disabled Pressing the Up or Down buttons will toggle the display between Enabled and Disabled. When enabled, the RF output from the MA4061B Upconverter is enabled. When disabled, the RF output from the MA4061B Upconverter is disabled. ( An RF output is only present when there is a valid IF input configured as described in the previous sections.
OUTPUT ENABLE/DISABLE When this mode is selected, the display will read: Output Enabled or Output Disabled Pressing the Up or Down buttons will toggle the display between Enabled and Disabled. When enabled, the RF output from the MA4070C Power Amplifier is enabled. When disabled, the RF output from the MA4070C Power Amplifier is disabled. TEMP When this mode is selected, the screen indicates the internal temperature of the amplifier.
3.2.3 MA4011B/MA4012B Power/Control Module Modes ADDRESS When this mode is selected, the display will read: Address XXX ( The displayed address is the currently selected MA4003 chassis Address. A different address can be selected by pressing the Up or Down buttons. The MA4003 chassis has an address from 001 - 999. The address is only used for remote control and monitoring purposes. The factory default address is 999.
This SNMP breakout feature has been added in order to provide the function of exiting from the SNMP control via the front panel. When the MA4012B power supply indicates SNMP SELECTED or SNMPext SELECTED, the modules in the chassis will be periodically polled and "R" is displayed in the corner of the display to indicate only remote control is allowed. SNMP Breakout Procedure To break out of SNMP control: 1. Press and hold the Module Select button for approximately 10 seconds. 2.
