1. Denotes warranted specifications. All others are typical.
2. Requires infinite persistence in order to visually display 1,000,000 wfm/sec.
3. Specifications are valid after a 30-minute warm-up period and ± 10 °C from firmware calibration temperature. 1 mV/div and 2 mV/div are a magnification of
4 mV/div setting. For vertical accuracy calculations, use full scale of 32 mV for 1 mV div and 2 mV/div sensitivity setting.
