5.9.3.11. ANALOG INPUTS (XIN1…XIN8) OPTION CONFIGURATION

To configure the analyzer’s external analog inputs option, define for each channel:

gain (number of units represented by 1 volt)

offset (volts)

engineering units to be represented in volts (each press of the touchscreen button scrolls the

list of alphanumeric characters from A-Z and 0-9)

whether to display the channel in the Test functions

To access and adjust settings for the external Analog Inputs option channels press:

5.9.4. ELECTRICAL TEST

The electrical test function creates a current, which substitutes the PMT signal, and

feeds it into the preamplifier board. This signal is generated by circuitry on the pre-

amplifier board itself and tests the filtering and amplification functions of that assembly

along with the A/D converter on the motherboard. It does not test the PMT itself. (See

also Section 12.5.7.2).
