For Olympus FocusPX, this will also require two devices.

	<p>If all you have is a single Pulser-Receiver and a single channel A/D board, you can do a P/E scan or a TT scan, but generally not both at the same time.

This is because the output signal of the pulser has to come from either the P/E source or the TT source.</p>		<p>If all you have is a single Pulser-Receiver and a single channel A/D board, you can do a P/E scan or a TT scan, but generally not both at the same time.

	<p>If the user only has one single-channel A/D board, it is possible to do simultaneous P/E-TT by combining the signal outputs of both pulsers using a JFW divider/combiner or similar device. Since the TT signal occurs later than the P/E signal, it is possible to set up gating that collects both results. This also depends on the type of transducer and the amount of delay between the reception of the P/E signal and the TT signal.</p>		<p>If the user only has one single-channel A/D board, it is possible to do simultaneous P/E-TT by combining the signal outputs of both pulsers using a JFW divider/combiner or similar device.
