The ideal generator for the TDR system should have an infinitely short rise time and a perfectly rectangular edge of the signal. As it is known, there are no ideals but you can try to get valuable parameters.
We have designed a TDR generator based on Step Recovery Diode (SRD). It will provide a short rise time - about 100ps and a smooth slope (we hope that). We are already sure of the rise time (confirmed by previous models), but the quality of the slope still requires work. At the moment PCBs are being made for the next version of the system.
- rise time: 100ps +- 20%
- amplitude: adjustable in range of 1..5V
- repetition rate: 1MHz
You can measure
even 1 nH !!!
