1. Connect the DUT to the test port of the PIM Master.
2. Press the Measurements main menu key to display the Measurements menu.
3. Press the Test submenu key so that On is underlined and the Test submenu key is outlined in Red. Testing begins.
4. Save the current measurement by pressing the Save Measurement submenu key. The Save Measurement dialog box opens.
5. Type a name for the measurement to be saved and press Enter. Refer to File Management for additional information about file handling.
DTP Measurement Example
The example DTP measurement that is shown in Figure: DTP Measurement Example displays two peaks, one at the jumper to feed line connection (refer to Marker 1 in the figure), and the other at the antenna (top of the tower, refer to Marker 2). With the aid of Markers, the exact location and amplitude is displayed in the Marker Table.
Note the amplitude of these two peaks. The site is passing its specifications, as determined by a PIM vs. Time measurement (DTP is for troubleshooting, not for pass/fail criteria). If Anritsu Line Sweep Tools (LST) is used to save this measurement, then other line sweeping measurements can be compared for this site, and later PIM measurements can be compared to observe for relative degradation over time.
Up to six markers can be placed on the trace at points of interest, and the marker table will display the signal parameters at each marker point.
