★ Data format: Loy, Phase, Smith, Polar, Lin, SWR , Real, Imagmary, Expand Phase, Positive Phase etc.
★ Analyzer Function
◆Fixture Simulator：Network de-embedding. Port reference impedance conversion. Matching circuit embedding. 4-port network embedding/de-embedding. Differential/Common port reference impedance conversion. Differential matching circuit embedding。
◆Absolute value measure: Amplifier harmonic distortion can be measured.
◆Limit Test : With limit, Ripide limit, Bandwidth limit testing function, Convenient for user to judge the products qualified or unqualified, thus greatly improving the testing efficiency.
◆Marker: The max total 9 marker can be displayed at the same time. Different curves of marker can be operated independently.
◆Marker search: Max, Min, Peak, Target, Tacking, Bandwidth search, etc.
★ Calibration methods
◆Full 4-port SOLT calibration.
◆Response calibration: Enhanced Response effectively eliminates the directivity error, crosstalk, source match error, frequency response reflection tracking error, and frequency response transmission tracking error from the test setup in a transmission or reflection test using those ports.
◆Port Expansion: In some cases, the user can not make a calibration on the testing interface, port expansion can make a compensation for the shift or delay between the testing interface and the device under test to meet the user and improve the testing accuracy.
◆TRL calibration: Effective for non-coaxial device measurement.
◆Power meter calibration: Calibrate the output power and level.
◆Receiver calibration: Calibrate the single receiver gain in absolute value measurement.
★ External Interface: USB 、LAN、RS232、Keyboard & Mouse PS/2 interface、 VGA、GPIB（option）。
★ Easy to make automatic control test system
◆Open windows XP operating system: Can use macros VBA programming. Interface : 6 USB, standard LAN and GPIB (option）。
◆GPIB、LAN Interface: Convenient to make automatic control test system。
◆LAN Interface: Convenient for the users to connect LAN,WLAN card, which is easy for users to carry out the remote data transmission.
