Description

3657 Series Vector Network Analyzers (9kHz/100kHz to 4.5GHz/9GHz)

The 3657 series vector network analyzer can be used in such fields as wireless communication, cable TV, education and automotive electronics for measuring the performance of RF components such as filters, amplifiers, antennas, cables and cable TV taps. The product has such functions as error calibration, time domain, fixture simulator, automatic fixture removal, advanced time domain analysis, with many display formats such as logarithm magnitude, linear magnitude, standing wave, phase, group delay, Smith pie chart, polar coordinates, etc. for multi-channel and multi-window display, as well as many interfaces such as USB, LAN, HDMI and DP. It can quickly and accurately measure the amplitude, phase and group delay characteristics of the S-parameter of the DUT, and has efficient and powerful error correction capability.

Main features

  • 3657 series has a dynamic range of up to 140dB for accurate measurement of devices with high rejection ratio
  • The test speed of 4us/point can greatly improve the production line test efficiency
  • Higher stability can meet the needs of high-precision testing;
  • Its functions are more abundant; in addition to the standard time domain analysis function, there are automatic fixture removal function and advanced time domain analysis function for selection
  • It is smaller in size and lighter in weight, and more testing instruments can be arranged in the same footprint.
  • 3657 has two models, namely, overhead (2U) and desktop (5U);
  • It has a four-port option, and a single connection can realize measurement of all 16
    S- parameters of the four-port network, and measurement of balance parameters;
  • 3657 has powerful data analysis capabilities, such as ripple test, bandwidth test, limit test and other functions, which is convenient for users to determine the qualification and improve the test efficiency;
  • 3657 has a LAN interface for remote control and system interconnection and comes with six USB ports
  • It can record SCPI instructions synchronously and generate scripts with one click.
  • It uses 12.1-inch screen to display multi-parameters on the same screen, with multi-touch operation.
