TYPICAL APPLICATIONS
Network Analysis
The 4957D/E/F microwave analyzer has the network analysis frequency range of 30kHz~18GHz/26.5GHz, 50MHz~40GHz, provides standard full 4S parameter vector network analysis and measurement capability and can carry out fully S-parameter analysis against amplifier, filter, attenuator and duplexer, and its display format includes logarithm, linearity, phase, group delay, impedance, polar coordinates, standing wave ratio, etc.
Spectrum Analysis
The 4957D/E/F microwave analyzer has the spectrum analysis function (spectral analysis, channel power, occupied bandwidth, adjacent channel power ratio, and frequency counting) and has a frequency range of 100kHz~18GHz/26.5GHz/40GHz, featuring with wide frequency bandwidth, high sensitivity, high dynamic range and good phase noise and has the capability of implementing fast and efficient signal detection and measurement. In addition, this analyzer can display 3 traces at the same time, and has provided different detector mode selections such as standard, sampling, positive peak, negative peak and average. What’s more, it has provided interference analysis, spectrogram, waterfall, data recording and playback.
Cable and antenna analysis (Optional)
As a cable and antenna analyzer, the 4957D/E/F microwave analyzer can measure the return loss, voltage standing wave ratio, impedance, cable loss, and fault point distance of the analyzed components such as cables and antennas, and return loss and Distance-To-Fault measurement will help user determine the specific cause of the fault in the cable and antenna system that degrades the overall system. What’s more, it has provided built-in common cable and antenna feeder parameters for easy use.
Vector Voltage Measurement (Optional)
The 4957D/E/F microwave analyzer has the vector voltage measurement frequency range of 30kHz~18GHz/26.5GHz, 50MHz~26.5GHz, which can accurately match and measure the electrical length and phase shift of the device under analysis, and can perform reflection and transmission analysis.
USB Power Measurement (Optional)
The 4957D/E/F microwave analyzer can perform power measurement by selecting the CETC 872XX series USB continuous wave power sensor, which can analyze the RF/microwave power up to 40GHz.
Power Monitoring (Optional)
The 4957D/E/F microwave analyzer can also be used for power monitoring measurements through the spectrum input port, and has a frequency range of 100kHz to 18GHz/26.5GHz/40GHz.
Field Strength Measurement (Optional)
The 4957D/E/F microwave analyzer can also be used for field strength measurement with the corresponding analysis antennas (such as CETGC’s 89101A/B/C/D, etc.), which is widely used in space electromagnetic environment monitoring and radio management. It supports user antennas, allowing users to customize their own antennas.
Supporting List Sweep
In addition to frequency sweep, including spectrum analysis, cable and antenna analysis, network analysis, etc., it also supports list scanning mode and makes the parameters in each segment become independent of each other.
Supporting Upper and Lower Limit Lines
Spectrum analysis, cable and antenna analysis, and network analysis support limit line analysis. The limit line can be used as a visual reference or as a basis for PASS/FAIL judgment. If the analysis data exceeds the upper limit line or is lower than the lower limit line, the speaker will send a “beep” sound to remind the user that the data is out of tolerance.
Menu in Both Chinese and English for Easy Operation
Both Chinese and English menus are available in the machine, which is very convenient to switch with one button.
Sleep and Energy Saving Function
It provides the function of displaying sleep for energy saving, set the sleep time, and when the sleep function is turned on and is not operated for a certain period of time, it will automatically turn off the display or shut down, thus saving energy, and effectively extending working time and life of battery.
More Markers
It provides up to 8 independent markers to display the parameters of the marker position, as well as provide maximum, minimum or peak search. Each marker provides a △ mode to make analysis readings become easier. In addition, the ruler on the left side of the display facilitates the judgment of the analysis results.
Automatic Software Upgrade through U Disk
The 4957D/E/F microwave analyzer provides a USB interface that can be used for software intelligent upgrade and data backup. User can conveniently use the USB flash drive to upgrade and maintain the instrument, which only takes a few steps to operate and is simple and quick. The instrument should be restarted after the upgrade.
Typical Applications
The 4957D/E/F microwave analyzer is characterized by compact size, light in weight, easy to carry, numerous analysis parameters and comprehensive analysis functions. What’s more, it is very suitable for multi-parameter analysis requirements and is battery-powered, serves as a powerful tool for routine maintenance and repair of field engineering installation and debugging of various microwave electronic equipment. In addition, it is widely used in radar, communications, radio and television, radio management and other fields. Besides, it is also an optimized choice for college teaching.
