Positioning Methods
Designate: Automatically moves the antenna in each axis to one of 99 pre-stored satellite positions. Direct Az/El: Automatically moves the antenna in each axis to the coordinates entered via the front panel. Jog: Manually moves the antenna in each axis in response to front panel controls.
Peak: Performs a peaking algorithm on the current target.
Step Track: Automatically performs peaking algorithm in response to input signal level decreasing below a programmable minimum.
Program Track:Automatically moves the antenna in each axis along a sidereal time tagged path.
External: Moves the antenna in each axis in response to commands received through the serial port.
Performance
Accuracy: Antenna pointing accuracy within ten percent of the 3dB beamwidth.
Tracking Resolution: > 0.05 degrees with properly specified position sensor.
Tracking Resolution: > 0.05 degrees with properly specified position sensor.
Interfaces
Reference: Accepts input of linear, analog signal reference from 0 - 20 VDC. Internal op amp circuit provides pre-scaling of gain and slope of tracking reference signal. Final scaling is provided through software.
Serial Data: Accepts RS-232 or RS-485 (4-wire) data for remote monitor and control of all controller functions.
M&C: Ethernet via RJ 45 10/100 Base T. Probecom monitor software suite.
Front Panel: Large Graphic VFD displays antenna position, signal level and operating mode. Keypad provided for user inputs.
Motor Control: The rack mounted microprocessor controller is linked to any of Probecom's motor control options by serial interface cable.

Power (ACU): 90 - 260 VAC, 47 - 63 Hz, single-phase, auto sensing, 65 watts maximum
Monitorand Control Software for AC3000 Antenna Controller
• Event triggered alarms - Any alarm conditions can be sent to the user via email to your cell phone. Events can be triggered via signal strength, AZ, EL & POL movements, communication errors and other threshold parameters.
• Large easy to read signal strength panel.
• Event triggered alarms / Easy to use email control. Email multiple users / Multiple alarm parameters.
• Status monitor – The status monitor panel allows for immediate real time data of your systems status.
• Strip Chart utility – Strip charting utility allows for recording of signal strength and AZ&EL motor movements.
Events are recorded and presented on time based event chart. Additional logging feature allows for tab delimited file that can be imported into your favorite spreadsheet program. The log files can be automatically saved and restarted on a daily basis and pulled up later for review of tracking performance.
• Revolving log file saving feature allows user to automatically back up log files for later analysis of controller events. Easily imported to Excel or other spread sheet programs.
