Capturing Data
63
3.1
Hardware Status
The lower right corner and the upper right corner of the main window display Hardware Status
information. This information will keep you informed of the hardware's buffer usage and capture
state.
Buffer Usage
The hardware buffer's usage is displayed as a bar graph and numerical percentage indicating
the used portion of the buffer. As data is stored in the buffer. the bar and the percentage will
increase. When the buffer reaches 100%, the data will be transferred to the PC for analysis.
The buffer may take mere milliseconds to fill or up to months to fill depending on the signals
defined (see: Signals 8 ) and the amount of activity on those signals. If you have configured
the buffer's prefill option to 'forced' (no early trigger), the buffer indicators may appear to stall.
This is correct behavior when very little or no signal activity is present or when the analyzer is
waiting for the trigger condition.
During a "waiting for Trigger" period, the analyzer continues to capture and store the newest
data in the prefill portion of the buffer, while discarding the oldest data. Once the trigger event
occurs, the buffer will stop discarding the oldest data, keep the newest data (the prefill portion)
and continue to capture until the buffer is full (see: Enforce Prefill in Analyzer Options 49 ).
To clear the buffer, click on the percentage indicator.
Analyzer State
The upper right corner of the main window will display the current state of the Analyzer using a
"light Bulb" symbol and a short text message (next to the run buttons), while the lower right
corner will display the state of the hardware as simple LED indicators with a letter abbreviation
for a reminder.
Message Example:
The 'Light Bulb" is lit, indicating that a trigger event occurred. The current status is
"Post-Filling", indicating that the remainder of the buffer is being filled with post-trigger data.
