 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.

 When configured to force voltage / measure current –V is added as in CA-V or when configured to force current / measure voltage –I is added as in CA-I. When a channel is configured in the high impedance mode to only measure voltage –H is added as CA-H. The fixed power and ground connections are referred as GND, +5 and +2.5. When configured to force voltage / measure current –V is added as in CA-V or when configured to force current / measure voltage –I is added as in CA-I.

-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.
