1. Maximum DC voltage limited
to
400 V DC in DSAC or SSAC
functions.
2. ±1°C and within 24 hours of
last ACAL ACV.
3. Limited to 1 x10
product.
4. Effective sample rate is
determined by the smallest
time increment used during
synchronous sub-sampling of
the repetitive input signal,
which is 10 ns.
5. <25 ns variability between
multiple 3458As
