Introducing IMD-TP1
A comprehensive solution for IMD characterization
Advanced, fully automated test system designed to simplify and accelerate inter-modulation distortion (IMD) measurements for linear power amplifiers, from LF to VHF. With its intuitive PC interface, it brings seamless control of power supplies, signal generators, spectrum analyzers and has precision filtering into one streamlined solution. Featuring automatic filter selection, the IMD-TP1 ensures maximum signal integrity with minimal setup time. Paired with ULTA-10 Ultra Linear Test Amplifier (250kHz–220MHz), it delivers highly accurate 3rd and 5th order IMD analysis — making it the perfect tool for RF Engineers and laboratories focused on high-power amplifier performance and reliability.
- IMD3 system performance: -70dBc typ.
- 2nd / 3rd harmonic system performance: typ. -65dBc / -57dBc
- automated testing: ensures high repeatability for dependable results
professional reporting: generates comprehensive engineering reports
