Imaginant Inc.

Repetition Frequency (PRF) value that is set by control software such as JSR .Net Control Panel.    To
synchronize the PureView operation to other instruments such as an oscilloscope or waveform digitizer, a
~4V positive-polarity Sync pulse is generated on the Trig/Sync connector in synchronization with the
transducer-excitation pulse.    This Synchronization Pulse can then be used to trigger an oscilloscope or
waveform digitizer to capture the waveform present on the PureView Output connector.    Additional
details of this mode of operation are contained in the Operation section.

PureView Status Indicators

The PureView front panel has Power and Pulse LED indicators that illuminate to indicate the instrument status
as shown in the image below.

The Power and Pulse LED indicators indicate the following:

Indicator

Function

Power

The Blue LED indicates that the PureView Pulser-Receiver is powered On. This LED can be set
to blink (if desired) to identify a particular PureView instrument in a system incorporating
multiple PureView instruments.

Pulse

This Red LED indicates that the unit’s pulser is being triggered. When triggered, the pulser
will produce transducer-excitation pulses on the T/R connector if the pulser voltage supply is
enabled.

PC Setup

JSR .Net Control Panel software is a Windows application written and distributed by Imaginant Inc. You may
install this software on a PC running the Windows

®

operating system version 7 with SP1, 8.0, 8.1 or 10. Once

you download the software, locate the software installer package and double-click the Setup.exe icon.
