Used ANDO AQ2140 #105283 for sale

ANDO AQ2140 is a high performance, automatic vector network analyzer (VNA) covering a frequency range from 10 MHz to 8.5 GHz. It is a type of electronic test equipment which is used to measure the electrical parameters of two-port networks such as impedance, scattering parameters, and most importantly, the gain and phase characteristics of linear electrical networks. AQ2140 is an ideal VNA choice for the research and development community as well as those applications requiring high performance VNA's. ANDO AQ2140 VNA consists of two parts, the mainframe and the electronic calibration kit (ECK). The mainframe consists of two components, the controller part and the measurement part. The controller part consists of the frequency synthesizer, pattern generator, command processor and GUI for user interface. The measurement part consists of the receivers, mixers and other components to generate and receive the reflected signals. The ECK is a calibration kit that includes a variety of components such as a power splitter, power source and variable attenuators. AQ2140 VNA uses a variety of techniques for amplitude, phase, gain and return loss measurements. It uses a through calibration technique for amplitude and phase measurements, as well as a source reflection method to measure the return loss of the network. It also uses a source vector method for gain measurement and a switched a reflect method for vector analysis. ANDO AQ2140 also has the ability to measure small signals with high sensitivity. It has a dynamic range of greater than 80 dB and a dynamic accuracy of better than 0.2 dB. In addition to the test and measurement capabilities of AQ2140, it has a number of additional features including data storage, multi-channel measurement capability, high-speed scans and pulse measurements. The data storage feature allows the user to store up to 10,000 scanned results in a single file on the hard drive. The multi-channel measurement feature allows the user to measure more than one network at the same time. The high-speed scans feature allows the user to scan up to 12,000 points in less than 30 seconds. Finally, the pulse measurement feature allows the user to measure pulses with rising and falling times of 300 nsec or less. Overall, ANDO AQ2140 is an ideal choice for a wide range applications requiring vector network analysis. It provides high performance measurements with high sensitivity and accuracy, and has a variety of features that improve its usability and convenience. This makes it an extremely reliable and versatile vector network analyzer for research and development of RF electronics.
