10.2.3 USB On-The-Go
USB On-The-Go option sets the Analyzer to record the USB On-The-Go traffic. This
protocol lets you run two devices, specify one of them as the host, one of them as the
device, and to assign each device a name.
10.2.4 Generator-related Parameters
You can set traffic generation parameters:
• Disable Generator Memory: Use the whole Capture Buffer for the trace.
• Default to IntelliFrame Mode: Rather than Bitstream Mode.
• Device Emulation Mode: Limit tracing to Channel 0. You can check
Device Resumes, then set the Delay Time Before Resume (in milliseconds, from
1 to 65535) and Resume Time (in milliseconds, from 1 to 65535).
You can set traffic generation parameters for the Device Address:
• Use Address in .utg file: The traffic generation file has an address.
• Emulated Device’s Hex Address (01-3F): Enter the Mask and Match for the
emulated device.
You can also enter the Host Chirp Reset Length (in milliseconds, from 1 to 69).
10.2.5 Data Truncation Option
• Truncate Data Fields (2.0): Allows data fields to be truncated during recording in
order to save Analyzer memory and allow recording of more packets. Enter a
minimum data length value in the Bytes box. The system truncates the data to the
stated value (or up to 5 bytes more to optimize operation efficiency in the Analyzer
hardware).
Note: Truncation of data may cause incorrect transaction or transfer decoding.
