The 4957D/E/F microwave analyzer has a frequency range of up to 18 GHz/26.5 GHz/40 GHz, and is provided with various functions, including dual port vector network analysis, cable and antenna analysis, vector voltage measurement, spectrum analysis (channel power, adjacent channel power, occupied bandwidth, interference analysis and frequency counting), field strength measurement and power measurement, providing users with powerful comprehensive analysis capabilities!
Dual-port vector network analysis has the capability of fast and accurate measurement of RF network parameters, provides logarithm, linearity, phase, group delay, impedance circle diagram, polar coordinates, standing wave ratio and other displaying formats and also provides time domain measurements option.
The cable and antenna analysis can measure the standing wave ratio, return loss, impedance, cable loss and other parameters of the microwave network such as antenna, transmission line and cable. In addition, the Distance-To-Fault (DTF) function enables to conveniently measure the impedance discontinuous point of the cable antenna feeder and cable.
The vector voltage measurement function replaces the traditional vector voltmeter with an integrated solution that accurately analyzes the electrical length of cables and other devices under analysis.
The spectrum analyzer is a standard function spectrum analyzer that comprehensively measures the spectral features of the electromagnetic environment.
The field strength measurement function features user-friendly interface and high analysis sensitivity, can effectively monitor the electromagnetic spectrum with the corresponding analysis antenna and is widely used in space electromagnetic environment monitoring and radio management.
The USB power sensor is configured to achieve large dynamic range and high-precision power measurement, or implement power monitoring through the spectrum input port.

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.
