Key Technical Data:

Testing Signals
Freq. selection: 698-960MHz transmit working freq.; 1800-2200MHz transmit working freq.; 2300-2700MHz transmit working freq.
Freq. accuracy: +2ppm, typical±5ppm, maximum (refer to N5182B signal generator manufacturer’s technical specifications).
Output power accuracy: ±0.25dB typical ±0.3dB maximum
System testing software: Chinese/English interfaces, power testing platform compatible with external signal generator (N5182B etc.), spectrum analyzer (N9010A etc.), power sensor (N1912A etc.), provide with remote monitoring test software.
Instrumental controlling: The system can be easily operated through IPC Software.
Working parameters setup: setups for signal freq., signal transmit power, power amplitude, system test on or off, as well as setup of testing system loss compensation etc.
Working mode selection: select continuous wave or pulsed wave testing modes.
Test power monitoring: real-time software controlled power sensor monitoring output average power, peak power and VSWR etc. also displayed on system software.
Warnings: support testing status indications, as well as abnormal working warnings. Allowed to setup warning thresholds and next emergency operation prompts.
Data access: test data and test curves allowed to save on hard-disk, easy to retrieve with software, supports database detection management.
Test result output: support auto test report generation, allows to generate and save test report using testing instrument or external PC.
System calibration: Testing software is capable to execute auto. calibration for testing system losses etc. of all testing routes,
calibration data will be auto retrieved when testing starts.
Protection and Inspection
Over-drive protection: when output power is larger than rated ( e.g. AVG>1000W), over-drive protection activates.
Over-current protection: when current output is larger than rated (200A), over-current protection activates, power supply without output or reduces output.
Over-voltage protection: when voltage output is larger than rated (28-32V), over-voltage protection activates, power supply without output.
Over-VSWR protection: the output port of the power amplifier open-circuit or short-circuit will not burning-down the Power amplifier, when power amplifier reflective VSWR>2, warning will be given or stops working immediately.
Breakdown detection method: Software supports monitoring power detection and VSWR variation.
Breakdown protection: Under auto detection mode, once breakdown has been detected (breakdown threshold provided by the customer, manufacturer default value is reflective VSWR>2 ), system automatically stops working to avoid further deterioration.
Over-heat protection: ≥60℃
Power indications: (± 0.25dB/100MHz) status indication, various warning indications, warning will be given with buzzer, timer function.
Interfaces type: impedance 50Ω, input ports on front panel, N-F type; output ports on front panel, 7/16-F type; VSWR<1.5, RS232, LAN & USD2.0 communication ports
System Software
Testing modes: continuous wave and pulsed wave
Remote control (optional): USD, LAN, GPIB
