Modes

Modes are applied to resources. Each resource can be in a different mode. The modes available with Surveyor depend on the underlying hardware resource as shown in Table 5-2 below:

Hardware Devices

The monitor and capture functions look at the same bit stream being received by a device. The difference between monitor and capture modes is how the bit stream is stored, viewed, and displayed by Surveyor. Because each device has different capabilities for storing and viewing the bit stream, you must understand the capabilities of the device you are using to completely understand what is possible in each mode.

The capabilities of each hardware device supported by Surveyor are described in Table 5-3. See Appendix A for more information on the implementation of Surveyor and a summary of all differences between hardware devices.
