<p>Two oscilloscopes were connected to Solenoid QD #2 Ch 8 using differential probes for diagnostic testing.</p>
<p>Oscilloscope #1 has a 830 mV trigger level (top scope in attached picture). Oscilloscope #2 has a 740 mV trigger level (bottom scope in attached picture). The attached PDF shows the points on the QD board where the probes were attached.</p>
<p>Attached is also a picture of the connections of the probes at the QD board.</p>
<p>Oscilloscope #1 has an ethernet connection, allowing it to be accessed remotely. Its IP is 129.57.96.41 with hostname hb-oscope.jlab.org. If its IP address or hostname are typed into a web browser on a Hall B subnet PC, the scope's web interface can be accessed. </p>
<p>To monitor Oscilloscope #2, a webcam (hostname hallbcam09.jlab.org) was set up. The camera's web interface can be reached by typing its hostname into a web browser on a Hall B subnet PC.</p>
