Utility Procedures Measuring Swept Return Loss Measuring Swept Return Loss This procedure measures the return loss (VSWR) of an antenna using an IBASIC program that is in the Test Set’s memory. An external directional bridge must be provided (such as an Eagle RLB 150X5 Option N5A or equivalent). Press the Menu key to access the SOFTWARE MENU screen, and follow the instructions illustrated on the following pages. Figure 3-4 Loading and Running the Return Loss Program Select ROM. Select RFTOOLS.
Utility Procedures Measuring Swept Return Loss Figure 3-5 Entering Swept Return Loss Measurement Information Enter the Start and Stop Frequency values for the measurement. The Max expected loss value is used to determine the graphics scaling when the measurement is displayed. The DUPLEX OUT level is adjustable to reduce the RF level used when measuring the loss of sensitive devices, and to minimize the amount of transmitted power during the test (if necessary). Select Begin Tst (k1) to continue.
Utility Procedures Measuring Swept Return Loss The plot in Figure 3-7 is for a cellular band antenna, swept from 800 MHz to 999 MHz. The plot (and the text above it) indicates that the maximum return loss is at 885.4 MHz. This is the point where the antenna is radiating the maximum amount of signal being fed into it from the return loss bridge, and therefore the Test Set is receiving the least amount of reflected (returned) energy back.
Utility Procedures Tracking Generator Tracking Generator The tracking generator is typically used for measuring return loss and insertion loss. It also allows for quick and accurate characterization of filters, duplexers, combiners, and RF to IF conversions. Broadband RF devices can be characterized with single sweeps due to the full-span sweep capability to 1 GHz. The tracking generator also includes amplitude and frequency offset.
