The Low and High Pass Filter settings for all channels using group settings can also be set on this tool
bar. The filters can be turned off, or the cutoffs can be selected from the values in the drop down menus.
The Notch Filter setting for all channels using group settings can be turned off, set to 50Hz, or set to
60Hz.
To modify the parameters for ALL channels at once, click on the Lock/Unlock Controls button on the
View Toolbar. The properties (including range, zoom, and filtering options) for all channels will now be
set using the controls on the View Toolbar.
Clicking on Reset Channels will reset ALL of the channel parameters to the default settings.
Clicking on Reset Heights will cause all channels to revert to the default height on the screen, which is
defined to give all channels an equal height.
Status Bar
Located at the bottom of the screen, the Status Bar provides real-time status of the data acquisition and RF
link operation. This information includes:
• RF Link Status: The bar graph shows an approximate measure of the signal strength from the
Transmitter. The bar shrinks when the received signal is getting weaker and there is greater chance for
losing data. The percentage displays the current percent of received packets from the transmitter.
When the percent of received packets is 100%, the percentage displayed is highlighted in green. When
this number drops below 100%, the percentage displayed appears highlighted in yellow. If this number
drops below 50% it is highlighted in red. This occurs because RF transmission is being impeded.
When this happens, move the Transmitter closer to the Receiver or remove the number of obstacles
between the Transmitter and Receiver.
• COM Port: Displays the current serial port setting for communicating with the Receiver.
• Output File Size: Displays the size of the
current output file, when recording data to
a file.
• Playback Speed/Timescale/Sample
Rate: Displays the speed of playback for a
file, timescale (viewing width), and the
sample rate of the Transmitter.
Setting Capture Options
Before capturing data with Capture, you must
configure the hardware.
