Figure 3.6 Connection Type for Return Loss/VSWR Measurement AV3680A mainly tests RF cable. Take the cable with length of 25m, radio frequency of 2.1GHz and VSWR of 1.05 as an example, this part makes a detailed instruction on test steps of return loss (Measurement steps of return loss and VSWR test are the same, therefore, it only takes return loss measurement as example here). - Page 15 Quick Start Guide for AV3680A Handled Cable & Antenna Tester Figure 3.7 Selection of Measurement Format 3. Press【FREQ/DIST】to enter the frequency menu; select [Start Freq] menu, then use the numeric keys, knob or arrow keys to input the start frequency value and select the corresponding unit menu to complete the input;...
- Page 16 Quick Start Guide for AV3680A Handled Cable & Antenna Tester Figure 3.9 Return Loss and SWVR Test Diagram at 2,100MHz Return loss or VSWR is the matching degree of DUT at each frequency point in the whole frequency band. Sweep span can be specifically set according to CAUTION operating frequency of the measured cable or DUT during measurement.

Page 24: Test Skills
As there have given a detailed description to the test steps for several test formats, this part will make a brief introduction on some common skills used in the measurement process. 1. Amplitude: AV3680A provides three ways for amplitude adjustment: First, through the top and bottom adjustment; Second, through automatic ratio adjustment; Third, through the adjustment on reference value, location and ratio. - Page 25 Figure 3.27 Return Loss Curve after Automatic Ratio Adjustment 2. Limit line: Users have their own eligibility criteria in batch test. In this regard, AV3680A provides 【Limit】 function for the setting of limit line, making it easier to test products. Thus, when large quantities of products need to be tested, it only needs to replace DUT and observe limit line to judge whether the product is qualified or not.
- Page 26 5. Cable Model: It has given detailed steps for setting velocity factor and cable loss in DTF test. To make it easier to test and set parameters, AV3680A offers a series of common cable models for user’s recall. Users can directly use[Cable Model] menu in the menu bar of 【FREQ/DIST】to enter the interface for cable model selection.
- Page 27 The more the sweep points are, the longer the measured maximum distance will be. In terms of cable loss, nominal value of effective directionality of AV3680A is equal to or more than 42dB. If the reflected signal energy is less than the effective directionality, the valid test result is not available.
