Tracking Generator
A tracking generator is a swept RF source that follows the analyzer frequency steps. It's typically used to test filters, amplifiers and cables. The tracking generator hardware from Siglent is included with all versions of the SSA3000X Plus family of spectrum analyzers.
All-Digital IF Technology
Siglent’s SSA3000X Plus Series of spectrum analyzers incorporate an all-digital intermediate frequency (IF) processing system. This core technology is designed to be faster, provide better resolution, and better accuracy compared to traditional analog IF designs. Digital IF allows for greater flexibility in signal analysis and processing, which is vital for modern applications like wireless communication testing (Wi-Fi, Bluetooth, RFID), EMI pre-compliance testing, and general R&D in RF circuits.
Siglent SSA3000X Plus Series
The Siglent SSA3000X Plus Series spectrum analyzers are powerful and flexible tools for RF spectrum and signal analysis with a frequency range to 7.5 GHz, the analyzer delivers reliable automatic measurements and multiple modes of operation. Typical applications for the SSA3000X Plus Series include broadcast monitoring and evaluation, site surveys, S-parameter measurements, analog/digital modulation analysis, EMI pre-compliance testing, research and development, education, production, and maintenance.
