| For the ALM1000 module we use the following terminology when referring to the connections to the connector and configuring the hardware. The analog I/O channel pins are referred to as CA and CB. | For the ALM1000 module we use the following terminology when referring to the connections to the connector and configuring the hardware.

| - | The ALM1000 hardware module is capable of producing and measuring single ended voltages from 0.0 to 5.0 V. It also can source and measure bipolar currents from -200 mA to +200 mA. It provides fixed +2.5 and +5 volt power supplies that can also source or sink up to 200 mA. The use of external voltage divider networks can extend the 0 to +5 V measurement range of the ALM1000 to almost anything depending on the resistor divider ratio chosen. | + | The ALM1000 hardware module is capable of producing and measuring single ended voltages from 0.0 to 5.0 V.

| The ALM2000 hardware module is capable of producing single ended voltages from -5.0 to 5.0 V. It can measure differential voltages well beyond that range but for purposes here we can confine the voltage range to that same -5.0 to 5.0 volts. It provides adjustable 0 to -5.0 and 0 to +5 volt power supplies that can also source or sink up to 50 mA. The waveform generator outputs include 50 Ω series termination resistors which will reduce to output voltage swing possible depending on the impedance of the load being driven. For example when driving a 50 Ω load the available output swing would be reduced to +/- 2.5V from the +/- 5V when the outputs are not loaded. | The ALM2000 hardware module is capable of producing single ended voltages from -5.0 to 5.0 V.
