Chapter 8 — One Port Cable Loss Measurement Testing

Introduction

This chapter provides an overview of performing Cable Loss measurements with the E7000L SitePROFILER Cable
Analyzer. The One Port Cable Loss measurement checks the signal attenuation level (insertion loss) of the
RF cable. Excessive cable loss will negatively affect cell site coverage.
This measurement can be especially useful in measuring the loss of feed line connected to the antenna. By
placing a short at the end of the cable or leaving it open, the signal is reflected back and the energy lost in
the cable can be computed. Cables with larger diameter generally have less insertion loss and better
power handling capabilities than cables with smaller diameter.

Setting Up a One Port Cable Loss Measurement

The following is a step-by-step guide for preparing to conduct a cable loss measurement using the E7000L
SitePROFILER cable analyzer.
Procedure:
1. To set the instrument in the cable analyzer mode, press the Menu button to view the measurement
mode desktop. Tap the Cable & Antenna softkey.
2. Tap the Measurement main menu softkey to open the Measurement menu on the right side of the
display. Under the Advanced submenu, select Cable Loss.
3. Tap the Freq/Dist main menu softkey. Under the Frequency submenu, set your desired Start and
Stop frequencies. There are two ways to accomplish this.
a. Manually enter the desired start frequency by tapping Start Freq and using the arrow keys,
data keypad, or rotary knob. Press Enter to confirm. Repeat for Stop Freq.
b. Open the Signal Standard submenu and tap Select Signal STD. Double-tap your preferred
signal standard on the list to select it and return to the submenu, then select the signal type
by tapping Uplink, Downlink, or Uplink + Downlink.
4. Still under Freq/Dist, open the Distance submenu. Enter the start and stop distance; be sure that you
toggle Dist Units to highlight the correct unit.
