Phase noise testing: The E8257D's excellent phase noise performance makes it an ideal reference for use in phase noise test systems, especially in the high-frequency band.
RF and Microwave Component and Device Characterisation: By adding AM, FM, PM and/or Pulse Modulation, the E8257D can accurately characterise RF and microwave components and devices for RF and microwave system design and verification.
Millimetre-wave testing: With the frequency expansion module, the E8257D can meet the frequency requirements of test systems up to 1.1 THz, suitable for communication system testing in the millimetre-wave band.
The E8257D PSG analogue signal generator is widely used in the communication industry, whether in radar, satellite communications or RF device testing, etc., and has demonstrated its excellent performance and flexibility.
What are the unique advantages of the E8257D PSG Analogue Signal Generator over other PSGs?
High output power: The E8257D's ability to deliver high output power means that users do not need to install additional external amplifiers for testing high power devices, thus reducing test cost and complexity and minimising test uncertainty.
Excellent level accuracy: The unit's very high level accuracy, which is important for accurate measurement and control of signal levels, helps to improve test accuracy and reliability.
Excellent phase noise performance: The E8257D has industry-leading phase noise performance, which is especially critical for applications such as performing native oscillator, low-jitter clock substitution, and adjacent channel testing, which are very sensitive to phase noise.
Wide frequency coverage: The unit's ability to cover a frequency range from 250kHz to 67GHz makes it suitable for a wide range of test scenarios, including the testing of radar systems, satellite communications, terrestrial microwave radio systems, and components.
Rich Functionality Options: The E8257D offers a wide range of performance enhancement options, such as output step attenuator, high RF output power, enhanced phase noise performance, AM, FM, phase modulation and LF outputs, pulse modulation, and narrow pulse modulation, which allow users to flexibly configure the unit according to their specific testing needs.
With its high output power, excellent level accuracy, outstanding phase noise performance, wide frequency coverage, and extensive feature options, the E8257D PSG analogue signal generator is the ideal tool for developing radar systems, satellite communications, land microwave radio systems and components.
