Chapter 9 — One Port Phase Measurement Testing

Introduction

This chapter provides an overview of performing One-Port Phase measurements with the E7000L SitePROFILER
Cable Analyzer. The One-Port Phase application measures S11 phase of a reflection measurement, which is
commonly used to tune antennas and phase match cables. It is also favored when one end of the cable
cannot be brought up to the test instrument – or in cases where "measure-and-snip" operations must be
performed to create cables of exactly the right phase length for a prescribed frequency.
The one-port phase measurement is most useful when making relative measurements (comparing the
phase of one device to the phase of another) by utilizing the Data Math function. See subsection 4-1.8 for
more details on Data Math in the Trace menu.)

Setting Up a One Port Phase Measurement

The following is a step-by-step guide for preparing to conduct a one-port phase 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 1-Port Phase.
3. Tap the Freq/Dist main menu softkey. Under the Frequency submenu, set your desired Start and
Stop frequencies to cover the normal operating range of the antenna or cable to be measured,
plus a suitable margin. 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.
