※ Installation Results Summary
| Test Direction | Axis | VC-Class (Base — floor) | VC-Class (Top — above Active) |
|---|---|---|---|
| ACTIVE | Z | C | E |
| X | C | E | |
| Y | D | E |
Good performance in all directions.
Vertical axis Z is C Class, the horizontal axis X is C Class, the horizontal axis Y is D Class. It was measured vibration environment in floor.
Vertical axis Z is E Class, the horizontal axis X is E Class, the horizontal axis Y is E Class. It was measured vibration environment in top of Active state.
Used data of internal program to making performance graph, show “Result 1”.
conversion unit in 1/3 octave band, Show “Result 2“.
conversion unit in ‘g’, Show “Result 3“.
As a result, contact the FEI korea, the equipment is new model. Because of the very high-magnification equipment, it is very susceptible to noise and vibration. Therefore, the environment is very important. Therefore, when determining the equipment installation site, FEI guys would have checked the floor vibration, noise and EMI effect. And when the first measurement, you must ensure that the environment is different now.
Result 1 <Performance graph used data of internal program – Transmissibility >
Result 1 — Z — Internal program transmissibility
Result 1 — Z — Autospectrum of table
Result 1 — Z — Autospectrum of floor
Result 1 — X — Internal program transmissibility
Result 1 — X — Autospectrum of table
Result 1 — X — Autospectrum of floor
Result 1 — Y — Internal program transmissibility
Result 1 — Y — Autospectrum of table
Result 1 — Y — Autospectrum of floor
Result 2 <Performance graph used data of PULSE – 1/3 Octave band>
Result 2 — Z — PULSE 1/3 octave band
Result 2 — X — PULSE 1/3 octave band
Result 2 — Y — PULSE 1/3 octave band
Result 3 <Performance graph used data of PULSE – g data>
Result 3 — Z — PULSE g data
Result 3 — X — PULSE g data
Result 3 — Y — PULSE g data
