1.3.1 STATIC SPECIFICATIONS
The static specifications are listed in Table 1-3. The BOP output effects, in response to the tabu-
lated variations in the Influence Quantities, are given In Table 1-3 for the built-in input and feed-
back resistor values of the voltage and current channel preamplifiers.
The tabulated Preamplifier Offset values (see Table 1-3) may be used to calculate the BOP out-
put effects if the BOP voltage or current channel is remotely programmed and different values
for the feedback resistors (R
f
) and the input resistors (Ri) are used. In this case, the tabulated
Preamplifier offsets and the values of the feedback and input resistors are combined in an “Error
Equation,” which represents the “Worst Case” output effect for the application at hand:
NOTE: Variations in the value of the feedback and input resistors are considered secondary
effects in the Error Equation.

(1) Output effects, expressed as a percentage, are referred to the maximum rated output voltage or current.
(2) Measured with the common terminal grounded so that the common mode current does not flow through the load.
(3) Peak-to-peak ripple Is measured over a 20 Hz to 10 MHz bandwidth.
(4) To permit calculating of the effect of non-standard control current (less than the normal 1 mA) of non-standard gain
ratios.
