Channel Sub-System

The channel sub-system configures the range of voltages the oscilloscope acquires and how the oscilloscope couples the input signal to the acquisition sub-system. The main channel sub-system properties include:

• IviScope Vertical Range
• IviScope Vertical Offset
• IviScope Vertical Coupling
• IviScope Probe Attenuation
• IviScope Channel Enabled

All of the channel sub-system properties are channel-based. They can be set individually or they can be set as a group with the IviScope Configure Channel VI.

Channel Sub-System Properties

The IviScope Vertical Range property specifies the absolute value of the range of voltages that the oscilloscope acquires. The IviScope Vertical Offset property specifies the center of the range specified by the IviScope Vertical Range property with respect to ground. The IviScope Vertical Coupling property specifies how to couple the input signal to the channel sub-system. The IviScope Probe Attenuation property specifies the scaling factor by which the probe attenuates the input signal. Typically, the value of the IviScope Probe Attenuation property determines the range values the driver accepts for the IviScope Vertical Range and IviScope Vertical Offset properties. The IviScope Channel Enabled property specifies whether the oscilloscope acquires a waveform for the channel.
