There is only one solution. Hard copy, not just hard copy but high paper rate copy. Copy where a full 110 mm width can be allocated to one of multiple channels, where the paper streams out at not less than 200 mm per second, 8 dots per mm, and 250 kHz real time. In street language that means you can see evidence of events which occur in 0.65 of a millisecond, or you can clearly see 1000 + Hz activity. The point is that now you have original detailed hard copy, playbacks are easily identifiable and valid at any scale, making truly substantial analysis possible.Product(s) / Service(s): LDI Services Source / Origin of Design: M.Packer US Contact Information: PO Box 506 Hampstead, NC 28443 USA Phone: 910.270.2737 Fax: 910.270.0320 Email: analysis@liquid-dynamics.com UK Contact Information: PO Box 47 Stockport, UK SK3-OLH Phone: 44(0)161-480-9625 Fax: 44-161-480-9627 Email: di@ldi.co.uk Web Site: http://www.liquid-dynamics.com/pulsation_and_shock_analysis_prediction_diagnostics_services... |
