The Peripheral Vascular Spectrum Analyzer is widely used in clinical departments to easily test the blood stream status of arterial/venous with a bi-directional Doppler power spectrum. The 3.2 inch TFT(320*RGB*240) provides real time monitoring, displays multiple predefined templates for power spectrum, PI, RI, SD and other hemodynamic parameters. High sensitive and muti-frequency probe design is optionally available. The bi-directional doppler power spectrum provides bi-directional continuous wave. The probe works at 8.0 MHz (5MHz for option), measures 2-200cm/s, works on 100-240VAC, 50-60Hz and contains built-in Ni-MH rechargeable batteries.
