Start
This button can be used to start monitoring the currently defined signals. The button will be disabled
(grayed out) whenever the Mil1394 Signal Monitor is already active.
Stop
This button can be used to stop monitoring currently defined signals. The button will be disabled (grayed
out) when the Mil1394 Signal Monitor is not active. After stopping the Mil1394 Signal Monitor the captured
data will remain loaded.
Clear
This button can be used to clear the captured signal values (data). This button will not clear the Signal
Definitions. This button will be disabled (grayed out) when the Mil1394 Signal Monitor is active.

Indicators
Active
This indicator will be on when the Mil1394 Signal Monitor is active and monitors signals.
Frames skipped
This indicator will be on when the Mil1394 Signal Monitor detected one or more skipped frames during the
currenly loaded capture.
Frame buffer
The Mil1394 Signal Monitor contains a memory buffer in FireSpy internal memory. The host fetches
frames of data from the FireSpy as quickly as possible. This indicator shows the fill level of the buffer in
FireSpy memory. When this indicator shows a value close to 100% then the host has problems keeping
up with fetching the data from FireSpy. You can then either reduce the number of signals being monitored
or try on a faster pc.
Skipped
This counter indicates how many frames were skipped during the current capture.
Last
This counter indicates how many frames were captured.
Selected
This counter shows the frame number currently selected. The plot view will show the cursor at this frame
number on the X-axis and the Signals View and Controls Views will show the signal values captured in the
selected frame number.
13.1.2.3. Signals View
The Signals View can be used to select signals to be monitored from a set of predefined signals or define
signals to be monitored manually. It also shows current signal values when the Mil1394 Signal Monitor is
active. Below a picture of the Signals View is shown. It contains the following components.
