Vector Network Analyzer VT4300
VT4300 Series Vector Network Analyzer is composed of high precision synthetic signal source, narrow-band receiver, high-speed embedded PC and Windows operating system. It features high-test precision, quick test, friendly operation interface and good test suitability. It has strong test function and widely used in wireless communication, broadcasting, CATV, education and research. It can test amplitude-frequency characteristic, reflection characteristic, phase characteristics and delay phase characteristics of RF components and device, like Amplifier, Coaxial Cable, Power Divider, De-multiplexer, Antenna, Coupler, Attenuator, Filter, Isolator and etc. 

It can quickly and accurately measure Insertion Loss, Return Loss,3dB Bandwidth, Attenuation, Isolation, Gain, Band Rejection, Impedance Bandwidth, Smith chart, VSWR, Group Delay, Phase, Frequency Response, and etc. 
Features
1. System impedance 50Ω or 75Ω,75Ω for CATV 
2. Windows operation system 
3. Dual-port and 4 parameter test (S11、S21、S12、S22) 
4. 10.4" colorful touch screen 
5. 4 separate channel and each channel parameter could 
be set separately to meet different test requirement of same component 
6. Storage function which can easily download to hardware or U stick 
7. Using Macroinstruction for VBA programming to realize auto test 
8. GPIB port is easily for customer to compose auto test system 
9. Connect to LAN or wireless network card for remote data transmission Like GPIB port, it can also used to compose auto test system 
10. 25ms sweeping time (201point,IFBW:30KHz) 
11. Multi-scanning mode:  Linearity Scanning, Logarithm Scanning, Fractional Scanning and Power Scanning 
12. Triggering Mode: Continuous, Single and Hold 
13. Strong analyzing function: 
     --Limit Test: it has Limit Test, Fluctuation Limit Test, Bandwidth Limit Test functions, which are easy for
        customers to decide pass or fail and improve the working efficiency. 
     --Frequency Marker: Max display 9 frequency marker at one time. Different marks from different curve could be
         operated separately. 
    --Frequency Marker Searching Function: Max Value, Min Value, Peak Value, Auto Frequency Marker Tracking,
        Bandwidth Searching, and Concave Peak Searching…. 
14. Special Calibration Method： 
      --Enhanced Response Calibration: it eliminates the error caused by directivity, cross talk，
        source matching,  back-reflection tracking and transmission tracking, and improve the test precision. 
     --Port Extension: in some occasion, customers cannot calibrated on the under test interface.
      With port extension function, it can meet the Phase Shift or Delay between Compensation Test Interface
       and Under Test Components to improve test precision. 

15. Multi External Port: USB,LAN, RS232, Keyboard PS/2, Mouse PS/2,VGA and GPIB(optional)
