Standard Universal Module Input Switch Configuration for COM A
3-68.
The A and B input amplifiers have independent LEVEL and SLOPE controls regardless of
the mode of operation (SEP or COM A).

OPTION
040 UNIVERSAL MODULE.
In COM A position, the INPUT B connector is
disconnected and the A and B input amplifiers are connected together at the INPUT A connector
as shown in Figure 3-15. As can be seen in the figure, the channel B AC-DC switch is disabled
when in COM A. The channel A AC-DC switch also determines the coupling for the channel B
amplifier. The impedance becomes 500 kN when in COM A and in the high impedance position
(and the input capacitance increases to approximately 65 pF). In 500 position, the impedance
remains 500 for COMA.
The sensitivity, dynamic range and damage levels remain unchanged.
