[1] BS440 has 4 analog channels each of which can select from a BNC or POD source.
[2] Analog bandwidth refers to the bandwidth of the analog input circuitry.
[3] The A/D convertor on each channel has a bandwidth is 75 MHz. BS440N includes compensation for this convertor to achieve 100 MHz bandwidth throughout.
[4] Specifies minimum viewable voltage with resolution enhancement.
[5] In addition to the fast sample rates, a wide range of "slow clock" and "burst clock" rates are supported (to below 1 Hz). Burst clocking also supports further increased bit resolution (ENOB).
[6] Specifies the maximum effective number of bits (ENOB) achieveable with resolution enhancement enabled.
