DTF measurement supports three data formats: ● Log Mag: Faults are displayed on the Y-axis in return loss format. expressed in unit dB. ● Lin Mag: Faults are displayed on the Y-axis in linear(unitless)format. www.siglent.com...
Page 224 10 dB of power. Considering DTF measurement is perfomed with 1 port, the signal traveled down the cable and then back, for a total loss of 20 dB. Cable Loss settings: www.siglent.com...
Page 225 Therefore, the window should be applied to gradually reduce the marginal frequency response and control the side lobe formed by the truncation. Click Meas > Distance to Faul > DTF[Port1]/DTF[Port2] > Meas Setup > Kaiser Beta/DTF Window to open the window setting interface and set the window. www.siglent.com...

It helps quickly locate the fault point on the cable, and preliminarily identify the fault type.If there is multiple mismatchs in the cable. The measurement steps are the same with DTF. www.siglent.com...
Page 227 Velocity Factor is a the ratio of the velocity of the electric signal in the cabl to that in the vacuum. For example, A polyethylene dielectric cable has VF =0.66 and a cable with PTFE dielectric has VF =0.7. www.siglent.com...
Page 228 Sidelobe level will be suppressed by applying window function, the larger the Kaiser beta is, the more obvious the suppression effect will be, but at the same time, it will increase the rise time of stimulus signal, thus reducing the resolution www.siglent.com...
Page 229 Gate Type: Set the type of filtering perfomed by the gating function. • Band Pass: Keep the response in the gating span. • Notch: Remove reponse using the gating span. Gate Shape: Set the filter characteristics of the gating function. There are four options: minimum, www.siglent.com...
Page 230: Insertion Loss Measurement
A 2-port Insertion Loss measurement is usually more accurate than a 1-port Cable Loss measurement. Insertion Loss Operating Steps: In the CAT measurement mode, click Meas > Insertion Loss to open the Insertion Loss setting interface, and select the Insertion Loss measurement. www.siglent.com...
Page 231: Return Loss Measurements
0 dB return loss is displayed.When measuring a LOAD, very little power is reflected and values of 40 dB to 60 dB are displayed. Return Loss Operating Steps: In the CAT measurement mode, click Meas > Return Loss to open the Return Loss setting interface, and select the Return Loss measurement. www.siglent.com...
Page 232: Cable Loss Measurements
Average cable loss can be measured, and Avg Cable Loss satisfies the formula: Avg Cable Loss = ∑ (measured cable loss)/number of points Cable Loss Operating Steps: In the CAT measurement mode, click Meas > Cable Loss to open the Cable Loss setting interface, and select the Cable Loss measurement. www.siglent.com...
Page 233: Vswr Measurements
The formula of VSWR is: (1+r)/(1-r) (where R is the reflection coefficient). Only valid for reflection measurement. VSWR Operating Steps: In the CAT measurement mode, click Meas > VSWR to open the VSWR setting interface, and select the VSWR measurement. www.siglent.com...
