Picometer Resolution Capacitance Measurement System
The D200HD is a two-channel, picometer scale, capacitance based, displacement measurement instrument for conductive targets.
The D200HD achieves very high resolution with the aid of external preamplifiers that are located close to the probes that eliminate parasitic capacitance effects which cause noise. Digital communication is provided via Ethernet or USB. The bandwidth and range extension of the probes are digitally programmable. Resolutions as low 20pm may be achieved with a 10um range probe.
Resolution ≤ 0.0000001 √(Hz) FSR Temp Amplifier useable from 0-40°C, Preamp up to 50°C, Probes up to 150°C Drift < 200 PPM / ° C (Amplifier & Probe Preamp ) Probe Standoff 10% of specified probe range Linearity ± 0.01% FSR (at 1X) Range extensions Up to 5X, and up to 10 range extensions per channel (2 standard) Digital Frequency response 5kHzt
