Keysight Technologies N5191A Signal Generator Details and Parameters In the modern field of electronic testing and measurement, signal generators serve as crucial equipment, providing indispensable stimulus signals for the research, development, production, and testing of various electronic systems. Keysight's N5191A signal generator, with its superior performance and advanced technology, stands out among numerous similar products and is widely used in cutting-edge fields such as radar, electronic warfare, and antenna testing. This article will detail the parameters of the N5191A signal generator to help readers gain a deeper understanding of this high-performance device. 1. Frequency Range The N5191A signal generator boasts an extremely wide frequency coverage range, reaching 10 MHz to 40 GHz. This wideband characteristic allows it to precisely meet various complex testing needs. Whether in the microwave frequency bands commonly used in the communication field or in emerging millimeter-wave applications, the N5191A can stably output high-quality signals. Engineers conducting experiments with different frequency requirements do not need to frequently change equipment; the N5191A's wideband design greatly improves testing efficiency and reduces equipment costs. 2. Output Power In terms of output power, the N5191A performs exceptionally well. At a frequency of 1 GHz, its standard output power reaches +10 dBm, providing sufficient signal strength for most conventional tests. Simultaneously, this model is equipped with an optional attenuator with a rapid adjustment range of up to 80 dB, allowing the minimum settable power to be as low as -130 dBm. This flexible power adjustment capability allows users to precisely adjust the signal power according to the sensitivity of the device under test and actual testing requirements, ensuring that the testing process neither damages the equipment due to excessive power nor results in the signal being undetectable due to insufficient power. This greatly expands the applicable range of testing. 3. Phase Noise Phase noise is one of the important indicators for measuring the performance of a signal generator; it directly affects the stability and accuracy of the signal. The N5191A has achieved industry-leading levels in phase noise control. When the carrier frequency is 10 GHz and the offset is 20 kHz, its typical phase noise is as low as -117 dBc/Hz. Low phase noise characteristics are crucial for applications with stringent signal accuracy requirements. For example, in high-precision radar systems, even minor phase noise can lead to deviations in target detection. The N5191A's low phase noise ensures high resolution and reliability of radar signals, effectively improving the radar system's ability to detect and identify targets. 4. Frequency Switching Speed The N5191A's frequency switching speed is exceptional. Within a frequency range of up to 31.6 GHz, its switching speed is only 100 μs; even when the frequency is extended to 40 GHz, the switching speed remains at 500 μs. This rapid frequency switching capability allows it to switch signals of different frequencies in a very short time, quickly generating complex frequency sequences. When simulating fast frequency-hopping communication systems, the N5191A can simulate rapidly changing frequency signals in real time, providing strong support for testing the anti-interference performance of communication equipment and ensuring that communication equipment can still operate stably in complex and changeable electromagnetic environments. 5. Modulation Functions The N5191A has a wide variety of modulation functions, including AM (amplitude modulation), FM (frequency modulation), PM (phase modulation), and pulse modulation. In terms of amplitude modulation, the modulation rate range is 0 to 10 MHz, and the maximum modulation depth can reach 80%. Users can flexibly adjust the modulation parameters according to their actual needs to generate signals with various amplitude changes. In frequency modulation, with a 100 kHz frequency deviation, the frequency modulation rate can reach DC to 10 MHz, capable of simulating signals with different frequency offsets to meet the testing needs of frequency modulation signals in fields such as wireless communication and satellite navigation. The integration of these modulation functions allows the N5191A to simulate various complex signal forms in practical applications, providing a comprehensive and realistic signal environment for the performance testing of electronic devices. 6. Pulse Characteristics The N5191A also performs exceptionally well in generating pulse signals. It can produce pulses as narrow as 10 ns, with a pulse rise/fall time of only 3 ns, meaning that the edges of the pulse signal are steep, allowing for more accurate simulation of the characteristics of actual pulse signals. At the same time, its on/off ratio is as high as 90 dB, ensuring good isolation between the on and off states of the pulse signal and effectively avoiding signal crosstalk. Using Pulse Description Word (PDW) technology, users can generate long pulse sequences and independently control the characteristics of each pulse, such as pulse width, pulse interval, and pulse amplitude. In electronic warfare system testing, it is necessary to simulate various complex pulse signal threats from the enemy. The N5191A's powerful pulse generation capability can accurately simulate these signals, helping electronic warfare equipment developers evaluate the anti-interference and signal identification capabilities of the equipment and improve the combat performance of the electronic warfare system. 7. Connector Configuration To facilitate connection with various testing equipment, the N5191A's connector configuration also fully considers user needs. For the 20 GHz model, a 3.5 mm (female) to 3.5 mm (female) connector adapter is provided. This common connector specification allows seamless connection with most devices with the same type of interface, ensuring the stability and reliability of signal transmission. The 40 GHz model is equipped with 2.4 mm (female) to 2.4 mm (female) and 2.4 mm (female) to 2.9 mm (female) connector adapters to adapt to the special needs of higher-frequency signal transmission, reducing signal loss and interference caused by connector mismatches, and providing reliable hardware support for high-frequency testing. 8. Other Characteristics In addition to the core parameters mentioned above, the N5191A also has several other practical features. It has a frequency resolution of 10 kHz, enabling high-precision frequency setting to meet testing scenarios with extremely high frequency accuracy requirements. In terms of automation and communication interfaces, it is equipped with 1000BaseT LAN, USB 2.0, and GPIB interfaces, facilitating integration with other testing equipment and computers to build automated testing systems, improving testing efficiency and data processing capabilities. This signal generator complies with the LXI standard, provides SCPI and IVI-COM drivers, and is compatible with Aeroflex fast switching signal generator code, further enhancing its versatility and scalability in different testing environments, allowing it to better integrate into various complex testing systems and provide users with convenient and efficient testing solutions. In summary, Rohde & Schwarz's N5191A signal generator, with its comprehensive and excellent parameter performance, demonstrates strong competitiveness in the field of electronic testing and measurement. Whether it is used in research institutions for cutting-edge technology research or in enterprise production lines for product quality testing, the N5191A can provide users with efficient and accurate signal generation services with its superior performance, helping to promote the continuous development and innovation of electronic technology. -
