2.6.4.3 Resistor-Programmable Gains (version 1 only)
The resistor-programmable gains option increases the versatility of the XVME-
500/590-l. In order to utilize these gains, it is necessary to install:
1)
A fixed-value resistor (value determined by equation following)
2)
A potentiometer (for fine adjustment of the gain), and
3)
A cut on the printed circuit board.
Installing Resistors To Modify Fixed Gain (Procedure)
1)
Remove power from the module.
2) Remove module from the cardcage.
3)
Locate the circuit trace in Figure 2-4.
Figure 2-4A shows the circuit
trace for the XVME-590/l).
