Impact of Changing Instrument Settings Parameters Input Bandwidth (not available with Signatec digitizers) Decreasing the Input Bandwidth decreases the response time of the detector, and can reduce higher frequency noise. A lower setting can improve resolution and smooth out a baseline, but may also decrease signal-to-noise ratio. Because the Input Bandwidth is an electronic analog filter, it may slightly shift peak centroids toward higher masses relative to peaks recorded with Full Bandwidth. Suggested settings Use the settings listed below as a starting point for Input Bandwidth. Adjust as needed to eliminate noise. NOTE: To maintain signal-to-noise ratio, use a lower Input Bandwidth setting. Input Bandwidth Mass Range (Da) Linear Mode Reflector Mode 0–500 Full Full 500–6,000 200–250 MHz Full 6,000–50,000 200–250 MHz 200–250 MHz >50,000 20–25 MHz 20–25 MHz PSD Mode 200–250 MHz or 20–25 MHz on PSD segments below 0.3 Mirror Ratio NOTE: Settings below 200 in Linear mode may not allow resolution of isotopes. 5 Voyager™ Biospectrometry™ Workstation User’s Guide 5-53
