In the development and verification of wireless communications and radio frequency (rf) devices, the signal purity, frequency-band coverage and modulation capabilities of signal-occupancy equipment are key to ensuring the orderly advance of testing. A wide-compatible, operating and stable signal generator is a good match to the performance test needs of various radio frequency modules and communication terminals. The angelen e4436b, as a classic radio-frequency vector signal generator, with mature hardware configurations and a rich functional module, has long been applied to a variety of scenarios such as communications development, radio-frequency device calibration, teaching and research, and is a basic test instrument of greater common use within the industry。
On the core frequency segment configuration, the device covers a range of 250 khz to 3 ghz and covers most of the civilian wireless communications, routine radio frequency test bands that are suitable for the testing of common devices such as radio frequency amplifiers, filters and antenna modules. The equipment has a good spectrum purity, the phase noise control is performed well, it is effective in reducing disruption of the test process by discrete signals, the output of more clean and smooth radio frequency signals, providing reliable signal baselines for the various routine radio frequency performance tests, and suitable for daily r & d and calibration work requirements。
The richness of the modem is one of the main advantages of this equipment. The equipment is compatible with a variety of modems, not only supporting conventional modems such as am, fm, pulse modems, but also with more than a dozen mainstream digital modems that match the signal simulation needs of different communication protocols. Combining 35 mhz radio frequency band bandwidth, 40 mhz sampling and 14-bit i/q resolution, the standards and customized wave-form details can be carefully adjusted to meet the needs for simulation testing of the diversity of signal profiles and calibration of different types of communication equipment。
The device carries a functional waveform storage and extension configuration, incorporates a waveform storage space from a 1m sample, supports the preservation and relaying of multiple sets of commonly used waveforms, and does not require repeated editing of waveform parameters in the context of repeated testing and standardized experimental scenarios, which can simplify the testing process and increase operational efficiency. At the same time, the equipment can be fitted with an arbitrary waveform generator and a real-time base belt generator, which can generate all types of sudden waveforms, customized waveforms, which can respond to non-standard test conditions and further broaden the use of the equipment。
The fit-for-modernity test needs, which can be used in combination with specialized testing software, capable of generating mobile communications that meet industry standards, wireless interconnection testing signals, adaptation of traditional communication equipment to the development, ageing testing and performance calibration of conventional wireless modules. The equipment is in a stable state of continuous operation, with relatively small fluctuations in parameters during long periods of continuous output signals, consistent output levels, suitable for long-term reliability testing and bulk sample testing。
The operational and fit level corresponds to popular use needs, equipment functional layouts are aligned, parameters are adjusted, mode-to-mode operation logic is aligned to the industry's generic norms, and it is difficult to do so. At the same time, conventional programming expansion is supported, which allows for the establishment of automated testing systems for off-site equipment, appropriate scientific step testing and enterprise-standard mass testing. Both teaching experiments in higher education and radio frequency testing at the enterprise's research and development end are well suited。
In terms of integrated overall performance, angeline e4436b does not focus exclusively on extreme performance, but rather on comprehensiveness and utility, with broad band coverage, multiple modem capabilities and stable signal output as its core characteristics. The integrated configuration is balanced and the landscape is highly adaptable, meeting the vast majority of routine radio frequency testing and scientific experimental needs and is a classic instrument of high utility in the field of radio frequency testing。
