7. Capturing Traffic
Supported wireless traffic in the vicinity of the analyzer and/or supported wired traffic attached to the analyzer
is not recorded until the user acts to capture this traffic (typically by clicking the Record button in the analyzer
software). Wireless traffic is captured over the antennas or via a conducted recording directly to the antenna
SMA antenna port. Wired traffic is captured at the Logic/GPIO connector and the USB HCI connection (Explorer
and Vanguard).
Traffic captured by the analyzer is temporarily buffered on the analyzer hardware then uploaded over the
Control Connection to the hard drive on the Control Computer, giving the user ample capture depth. For very
long capture sessions, an automatic segmentation feature allows the user to automatically separate one long
capture into smaller, more manageable captures by rolling a capture over from one to the next based on time,
file size, or both (see Recording Options | Capture Management).
An alternative browser-based remote capture feature is also provided (see
Section 7.14. Using the Web Control Interface.
Traffic may also be captured
using the remote API or CLI, which can be downloaded from a link provided in
Section 26, Remote API and CLI
.
The analyzer is designed such that little to no configuration is required to take a capture, although the
Recording Options
menu provides for inclusion and exclusion of selected traffic types as well as an optional
user designation of pins to be used for captures taken using the wired Logic/GPIO Connection.
7.1 Analyzer Hardware Setups
The basic setups for taking a wireless (over-the-air) recording are described in this section. The analyzer is
connected over the Control Connection to the Control Computer that hosts the analyzer application. The Control
Connection is used to program the analyzer for any capture characteristics selected by the user, and to upload
traffic to the analyzer application. Depending on the model, this connection may also be used to power the
unit (Tracker and Vanguard).
When successfully connected, the analyzer’s serial number will be visible in Record | Select an Analyzer.
