Sample Instrument .xml File

The following example illustrates a sample structure for an instrument .xml file. The instrument used in this example is an Elektro-Automatik Bidirectional Power Supply.

<?xml version="1.0" encoding="utf-8" ?>
<EA-PSB Category="Cycler">
    <InstrumentChannel Path="Voltage Setpoint">
        <VoltageInputAttributes Unit = "Volts"
		MinValue = "0" MaxValue = "600"/>
    </InstrumentChannel>
    <InstrumentChannel Path="Voltage Feedback">
        <VoltageInputAttributes Unit = "Volts"
		MinValue = "0" MaxValue = "600"/>
    </InstrumentChannel>
    <InstrumentChannel Path="Current Setpoint">
        <VoltageInputAttributes Unit = "Volts"
		MinValue = "0" MaxValue = "600"/>
    </InstrumentChannel>
    <InstrumentChannel Path="Current Feedback">
        <VoltageInputAttributes Unit = "Volts"
