Page 119: Distance To Fault Measurements
The distance to fault (DTF) measurement determines the exact location of possible faults in a transmission system. If you connect the end of the cable to the R&S ZNH, the DTF measurement shows you the exact distance to the fault (in meter or feet), regardless by what the fault is caused.
Page 120 Because of its sensitivity by first measuring in the frequency domain and subsequent IFFT, the measurement is able to locate faults in a cable accurately. To keep this accu- racy, the R&S ZNH also accounts for any attenuation that occurs over distance in a cable.
Page 121 The R&S ZNH displays the DTF configuration submenu. 3. Select "Split Screen" softkey. The R&S ZNH displays the DTF measurement in the top screen window and the reflection measurement in the bottom screen window. 4. Tap on the desired trace window to select the screen window.
Page 122: 1-Port Cable Loss Measurement
By default, the R&S ZNH evaluates the cable loss over its entire frequency range (full span of the R&S ZNH). When you reduce the span, make sure to define a span that is appropriate for the measurement, especially for high center frequencies, and consider the cable length and the wavelength of the selected center frequency.

Cartesian diagram with a linear vertical axis. The horizontal axis repre- sents the measured frequency range. In the default state, the R&S ZNH shows the phase only from -200° to +200°. In that case, the R&S ZNH displays measurement results correctly only if the phase difference between two adjacent test points is less than 180°.
Page 127: Calibrating Measurements
"Delay Time" - Enable or disable the check box to display cable delay time. 7.1.7 Calibrating Measurements In its default state, the R&S ZNH uses factory calibration. Factory calibration is a full 2- port calibration over the full frequency range (i.e. span) of the R&S ZNH. When the fac- tory calibration is active, no calibration status is shown on the trace label.
Page 128 Calibration also remains valid after turning off the R&S ZNH or changing into another operating mode as calibration data is saved in the internal memory of the R&S ZNH. If you save the measurement in a dataset, calibration data is part of that dataset. When you restore the dataset and perform the same measurement again, you do not have to recalibrate the R&S ZNH.
Page 129 "Trans Norm P1", "Trans Norm P2" and "Trans Norm Both". User calibration After a user calibration is performed, the R&S ZNH allows you the option to apply user calibration ("cal" or "norm") or resume factory calibration data on the measurement.
Page 130: Configuring Cable And Antenna Tests
If you want to test a cable that is not listed, you can also define cable models manually, either directly on the R&S ZNH or with the "Cable Model Editor" of the R&S InstrumentView software package that is delivered with the R&S ZNH.
Page 131 The R&S ZNH opens the file manager to select a cable model. 5. Select the cable model that you are testing. The R&S ZNH loads the selected cable model. Note that the selected cable model is also displayed in the title bar.
Page 132 The first way is to define a cable model with the "Cable Model Editor" that is part of the R&S InstrumentViewsoftware package. The R&S InstrumentView is delivered with the R&S ZNH. With this software, you can define a cable model on a computer and then transfer it to the instrument.

2. Select "DTF Config" softkey. The R&S ZNH displays the DTF configuration submenu. 3. Select the "DTF List" softkey. The R&S ZNH opens a table that lists the peaks it has found during the measure- ment. 1 = Shows the peak results 2 = Shows the distance from the measurement plane to the peak.
Page 134 Setting the Frequency Range for DTF Measurements In the default settings, the R&S ZNH automatically selects a center frequency of 1 GHz and a distance of 50 m. The R&S ZNH optimizes the settings for the best resolution, if you change the stop distance.
Page 135 The R&S ZNH adjusts the frequency range according to your settings. Note that the distance from start to stop frequency has to be equal to the span. The R&S ZNH adjusts the values if you enter a frequency range that is not the same as the span.
Page 136 In auto span mode, the R&S ZNH adjusts the frequency settings in order to get the best display resolution. If you have set the span manually, the R&S ZNH zooms in to the section of the cable you have defined. The results maintain their accuracy in that case.
Page 137: Configuring The Vertical Axis
When you change the reference value, the R&S ZNH adjusts the labels of the vertical axis. Changing the reference value results a change in the vertical position of the trace.
Page 138 The "0" value corresponds to the top grid line and the "10" corresponds to the bottom grid line. When you change the reference position, the R&S ZNH also shifts the position of the trace by the magnitude of the reference position change. It has no effect on the refer- ence value itself.
Page 139: Configuring The Tracking Generator
The R&S ZNH opens an input field to specify the measurement bandwidth. 3. Enter the measurement bandwidth you require. As an indicator that the "Meas BW" is no longer coupled to the span, the R&S ZNH displays a blue dot in front of the "Meas BW" item in the parameter view.
Page 140: Setting The Measurement Sweep
Single sweep mode performs the sweep in the defined span once, then the R&S ZNH goes into an idle state. If the trace averaging is set, the R&S ZNH performs the sweep a certain number of times (depending on the number of averages you have set) over the defined span and then stops measuring.

Page 142 7.3.1.3 Working with Memory Traces The R&S ZNH can transfer a trace to the trace memory and also display the current trace and the trace in the trace memory for comparison. The saved trace is always dis- played in a lighter yellow to distinguish it from the current trace. See Figure 7-9.
Page 143: Using Markers
7.3.2.1 Using Markers and Deltamarkers The R&S ZNH has six markers, five of which can be used as either markers or delta markers. The markers cannot leave the trace and indicate the horizontal and vertical coordinates of the point they are positioned on.
Page 144 ® Cable and Antenna Test Mode R&S Analyzing Measurement Results the delta marker level unit is always dB. The delta marker frequency is always relative to the main marker – in other words, the delta marker frequency is the frequency differ- ence between the frequency at the point marked by the main marker and the frequency at the point marked by the delta marker.
Page 145 The R&S ZNH activates a delta marker and positions it on the next maximum level that has been measured. In addition, the delta marker input field opens. The R&S ZNH adds the delta marker to the marker list and shows the marker posi- tion relative to the normal marker (M1).
Page 146 M2) and its coordinates are now absolute values. Automatic Positioning of Markers The R&S ZNH offers functions that make setting the markers easier or allow to make instrument settings on the basis of the current marker position: 1. Press the [MARKER] key.
Page 147 3. Select the "Delete All" menu item. The R&S ZNH deletes all markers and delta markers. Using Marker Search Limits The R&S ZNH allows you to use only a limited section of the trace for the marker auto- matic positioning functions. See "Automatic Positioning of Markers"...
Page 148 7. Confirm the entry with one of the unit keys. If the span is wide enough, the R&S ZNH displays a blue and green line to indicate the limit line for "Search Range 1" and "Search Range 2" respectively. By default, the search limit range is over the whole span.
Page 149: Using Display Line
1. Press the [LINES] key. 2. Select the "Display Line" softkey. The R&S ZNH displays the display line as a blue horizontal line. It shows the verti- cal position of the line in a table above the diagram area. When you activate the display line, the R&S ZNH also opens an input field to define the vertical position of the line.
Page 150 Values that define the vertical characteristics are always level values in dB. If the scal- ing of the vertical axis is currently a linear one (units V or W), the R&S ZNH automati- cally switches to a logarithmic scaling after you turn on the limit line.
Page 151 Before selecting a limit line, you need to decide if you want to use it as an upper or lower limit line. In case of upper limit lines, the R&S ZNH checks if the signal is above the limit line. In case of lower limit lines, the R&S ZNH checks if the signal is below the limit line.
Page 152 As long as the signal does not violate the limit line, the R&S ZNH shows a "Pass" message in the measurement diagram. When one single value (i.e. one pixel) is outside of the limits, the R&S ZNH displays a "Fail" message in the diagram area and, in addition, sounds a beep.
Page 153: Vector Network Analysis
The network analyzer mode provides the functionality to characterize networks with one or two test ports. All R&S ZNH models have a tracking generator and VSWR bridge that are necessary to use the network analyzer. The network analyzer provides measurements to deter- mine the reflection or transmission characteristics in both directions of the device under test (DUT).
