■ Impedance analysis of piezoelectric ceramics, ultrasonic transducers and other devices

 ■ System impedance: 50Ω or 75Ω, suitable for CATV users.

 ■ Instrument interface: Chinese or English

 ■ Double-ended test: Simultaneously test 4 S parameters (S11, S21, S12, S22) of two-port devices, which greatly improves the test efficiency.

 ■ WindowsXP operation interface: 10.4-inch TFT color LCD display, touch screen, clear display, simple and quick operation.

 ■ 4 independent measurement channels: each channel can independently set source parameters to meet the user's test requirements for the same device under different conditions.

 ■ With storage/recall function: the measurement results can be saved on the hard disk or U disk.

 ■ Macro instructions can be used for VBA programming: automatic control test.

 ■ LAN interface: It is convenient for users to connect to local area network and wireless network card, and it is convenient for users to carry out remote data transmission and form an automatic test system.

 ■ Data format: logarithm, phase, group delay, Smith chart, polar coordinate, linear, SWR, real part, imaginary part, extended phase, positive phase, etc.

 ■ Scan mode: linear scan, logarithmic scan, segment scan, power scan.

 ■ Trigger mode: continuous, single, hold.

 ■ Powerful analysis function:

    Limit test: limit test, fluctuation limit test, bandwidth limit test, etc. Users can screen for qualified and unqualified products.

    Frequency markers: 9 frequency markers are displayed at the same time, and the frequency markers on different curves can be operated independently.

    Frequency mark search function: maximum value, minimum value, peak value, automatic frequency mark tracking, bandwidth search, concave peak search, etc.

 ■ Unique calibration method:

    Enhanced response calibration: It can eliminate directivity, crosstalk, source matching, reflection tracking, transmission tracking errors, and improve measurement accuracy.

    Port expansion: In some cases, users cannot perform calibration on the test end face. Port expansion can satisfy the user to compensate for the phase shift or delay between the test end face and the DUT, and improve the test accuracy.

■ Numerous external interfaces: USB, LAN, RS232, keyboard PS/2 interface, mouse PS/2 interface, external VGA display interface
