Coupling : DC
Impedance : 1 MΩ in parallel with 25 pF (nominal)
Ranges : A/D responds to the difference of the two input voltages on
the(+) and (-) connectors.
-0.10225V to 0.10230V
-0.2045V to 0.2046V
-0.51125V to 0.5115V
-1.0225V to 1.0230V
-2.045V to 2.046V
-5.1125V to 5.115V
-10.225V to 10.230V
-20.45V to 20.46V
-51.125V to 51.15V
-102.25V to 102.30V
Overload: On-the-fly flagging includes amplifier overload. Ranges 0.1V to
5V: input impedance remains nominally constant up to ±10V.After removal
of ±20 Vpk input, recovery is typically to within 1% of peak-to-peak
full-scale in 250 µsec. Ranges 10V to 100V: input impedance remains
nominally constant upto ±102.3V. After removal of ±100Vpk input,
recovery is typically to within 1 % of peak-to-peak full-scale in 30 µsec.
Never exceed ±102.3V input.
CMRR : Ranges 0.1023V to 5.115V:
for |Vcm|<= 10 volts peak and slew rate <150 v/µs:
DC: >68 dB
AC: >60 dB (1 MHz)
Ranges 10.23V to 102.3V:
for |Vcm|<=102.3 volts peak and slew rate <1500 v/µs:
DC: >45 dB
AC: >40 dB
CMRR is measured by applying a signal from a 50Ω through a "Tee"
connector to both inputs.
