* Specifications (valid within ± 10° C of auto-calibration temperature, excluding bandwidth−see note 1 for bandwidth specification.)
1. Upper bandwidth reduces by 2.5 MHz for every degree C above 35° C.
2. Specification applies to the maximum sampling rate. At lower rates, the specification is:± [(0.005% x ∆t)+(2 x 10
-6
x delay setting) +
(0.15 x sample interval)] for bandwidth limited signals (t
