Digital Output Characteristics¶
The AL-1010 supports a variety of ways to configure a system that can output a digital state or PWM output to a device under test. The following sections outline what configurations are available and what control modes are compatible with each configuration.

BUS+/-, Open (Internal State)¶
The module controls a voltage from LOAD, AUX1 or AUX2. When the state is high, the source is connected. When low, the source is disconnected.

AL.PWM_Period |
Physical Channel |
UInt32 |
Set period time for PWM generator. The period time is set in multiples of 10 ns. The minimum value that can be set is 2, this will set the period time to 20 ns (50 MHz). |

AL.PWM_DutyCycle |
Physical Channel |
UInt32 |
Set duty cycle for PWM generator. The duty cycle is set in multiples of 10 ns. |
1..4294967295 |
AL.PWM_PhaseOffset |
Physical Channel |
UInt32 |
Set phase offset for PWM generator. To set phase offset x [degrees] use this formula to calculate the phase offset value: PH = (x/360) * PER |
