Amplitude Window ( only available with Ultra Receiver )
– The amplitude window
defines the dynamic range of the signal that is recorded. The larger amplitude windows
will collect a wider range of amplitude values, but smaller amplitude windows will record
more precise amplitude data. This also determines the resolution of the digitally
sampled signal.
Pressing the + and - buttons under Amplitude Window in Figure 5-36 will increase or
decrease the vertical scale. Remember that the value shown is the entire range, so if
1000 mV is selected, then the scale goes from -500 mV to +500 mV. Unless clipping of
the signal is desired, the amplitude window should be large enough to encompass the
maximum amplitude of the pulse.

Auto Amplitude Window
– pressing this button will automatically search for the
smallest amplitude window that does not clip the signal, and adjust the scale
accordingly.

Note : if the pulse cannot be found, and all connections are made, check the batteries in the
transmitter. If the batteries are OK, there could be a problem with the transmitter.
5.2.6 GPS
The GPS test will ensure that the system is communicating properly with the GPS and receiving
data. Pressing
GPS will show the screen in Figure 5-37.
