The Low Frequency Tuner (LFT) is a unique product technology using M algorithms for low frequency wideband tuning. Three or more cascaded tuning sections use series transmission cables and parallel rotary capacitors. The length of the cables and number of tuning sections are optimized for maximum tuning range over a given bandwidth. HLFT tuners use 6 tuning sections allowing second harmonic frequency tuning.

-
Ease of use – Less experienced operators can perform an RF calibration up to 500 GHz by simply pushing a button. This reduces the need of experienced users full time on each system.
-
Reduced Soak Time – The system will automatically re-align the probes to the pads if they drift from alignment. This reduces test time and increases throughput.
-
Unattended Use – Measurements can be left running over night or the weekend, testing all devices on the wafer, and at different temperatures without the need of an operator.
-
Calibration Monitor and Re-calibration – System will continuously monitor calibration drift, and automatically re-calibrate the system should the drift exceed a predefined limit.
