-As in all the ALM labs we use the following terminology when referring to the connections to the M1000 connector and configuring the hardware. The green shaded rectangles indicate connections to the M1000 analog I/O connector. The analog I/O channel pins are referred to as CA and CB. 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.+As in all the ALM labs we use the following terminology when referring to the connections to the ALM1000 connector and configuring the hardware.

 Scope traces are similarly referred to by channel and voltage / current. Such as CA-V , CB-V for the voltage waveforms and CA-I , CB-I for the current waveforms. Scope traces are similarly referred to by channel and voltage / current.

 This configuration allows the oscilloscope to look at the input voltage of the circuit and the current through the inductor on channel A and the output voltage of the circuit on channel B. Make sure you have checked the Sync AWG selector. This configuration allows the oscilloscope to look at the input voltage of the circuit and the current through the inductor on channel A and the output voltage of the circuit on channel B.
