Connect the power cable to the power jack of Pulsarand plug it into an AC outlet. The power cable is already included in the package accessories. ▪ Power Up Pulsar. ▪ Connect the device to the network* using a RJ45/LAN cable.
Figure 3: Connection failure notification. *To add the device to the network, consult Appendix I at the end of this manual Connection & Mode Selection After connecting to the instrument by typing its IP in the appropriate text box, select the desired mode of operation and press “Configure”.
This section will list and explain how to perform all measurements that fall under this umbrella. Time-Domain Reflectometry TDR can be used for many applications, such as to characterize the impedance of DUTs, backplanes, and other physical media, locating faults, discontinuities or breaks along a cable, cable matching, and more.
▪ Disconnect the twinax (SMPM to 2.4 mm) cable from the host and click on “Confirm”then “done”. Figure 6 Confirm Alignment ▪ Close the page to exit the calibration wizard. ▪ Plug the OSFP/QDD connector in the host. TDR Measurement ▪...
Figure 7 Impedance profile Graph. Locating Faults & Discontinuities One popular application for TDR is locating faults and discontinuities in a physical medium. As the velocity of propagation of electromagnetic waves in vacuum is known, additional information related to the characteristics of the physical medium such as the copper cable’s velocity of propagation (VoP) allows the speed of propagation to be estimated and the distance between two points can therefore be calculated.
Figure 9 Ohm Offset It is also possible to add a positive or negative ohm offset to each/all channels. User defined mask Figure 10 User defined mask The user can define in the measurement section a custom mask by setting the minimum and maximum time, as well as impedance.

− Return Loss Pulsar can also be used to measure return loss. Similarly to impedance profile, Pulsar performs a TDR measurement in time domain and then converts it to the frequency domain, resulting in return loss measurements.

Return Loss Measurement Press to measure continuously or for a single capture. Figure 16 Return Loss Measurement Measurements and masks can be loaded in the software by pressing “Measurement” on the bottom right side of the page. The available measurements for return loss are loss at Nyquist and the return loss mask, for which the mask type is available for different standards that the...
Appendix 1 – Adding Pulsar to the Network To create a local network connection, please follow these steps: ▪ Create a local network connection between the laptop and Pulsar using Internet Protocol Version 4 (TCP/IPv4). o Open “Control Panel” and choose “Network and Internet”.

This will be used to ping the instrument once the IP Address is changed to match that of the network. ▪ Connect the laptop directly to Pulsar using an Ethernet cable. ▪ Copy the IP Address found on the back of the unit.
