5.2. Instrument Setup
5.2.1. Recalling a State File
This section describes how to recall an instrument setup file on the ENA. The file includes
all the measurement settings for BroadR-Reach link segment tests. Copy the state file to
the ENA directory via an USB mass storage device and recall the state file using the TDR
software. Necessary parameters for testing are automatically set up on the ENA. Refer to
the Appendix for the details on manually setting up the instrument.
If the TDR Setup Wizard is shown, click the Close button in the TDR Setup Wizard main
window.
1. Open Setup tab.
2. Click Advanced Mode.
3. Click Yes. (Uncheck "Use Advanced Calibration Methods")
4. Click File and select Recall State to open the Recall State dialog box.
5. Specify a folder and a file name, and click Open.
The ENA channel 1 is controlled by the TDR software and Channel 2 is controlled using
the soft keys on the right side of the screen, or hard keys on the front panel.

5.2.2. Saving a State File
All the measurement settings, including calibration information, can be saved to a state
file (*.tdr). When saving a state file after performing calibration, all necessary calibration
coefficients can be saved in the state file and can be recalled for subsequent
measurements.
1. Press Save/Recall > Save Type and select State & Cal as a state file type.
2. Click File of the TDR software.
3. Select "Save State".
4. Enter file name and save the state file with calibration information.

5.3. Calibration
5.3.1. Channel 1 Calibration
The purpose of this step is to calibrate out the delay, loss, and mismatch of the test
cables for measurements in channel 1. Full calibration is performed by using the 4-port
ECal module at the end of test cables connected to the ENA test ports. After connecting
the test fixtures to the cables, the delay of the fixtures is removed by the fixture
compensation function.
5.3.1.1. ECal Calibration & Fixture Compensation
Calibration for Channel 1 is performed from the TDR software. The 4-port ECal module (i.e.
N4431B) is necessary for the calibration procedure.
1. Press Channel Next to select Channel 1.
2. Click Setup tab of the TDR software.
3. Click ECal to launch calibration wizard.
4. Connect all test cables to the ECal Module and click Calibrate. Once the green check
mark appears, click Next>.
5. Disconnect the ECal Module and connect the test fixtures to the test cables. Click
8
Keysight Technologies MOI for BroadR-Reach Link Segment Tests
Fixture Comp to perform fixture compensation. Once the green check mark appears,
click Finish to complete the compensation.
6. Connect DUT to the test fixtures.
7. Click Setup tab.
8. Click Auto to launch the DUT Length dialog box.
9. Click Measure to measure the DUT length. Once the green check mark appears, click
Finish.

Keysight Technologies MOI for BroadR-Reach Link Segment Tests
10. If the DUT Length value is less than 15 nsec, manually enter 15 nsec.
5.3.2. Channel 2 Calibration
The purpose of this step is to calibrate out the delay, loss, and mismatch of the test
cables for measurements in channel 2. Full calibration is performed by using the 4-port
ECal module at the end of test cables connected to the ENA test ports. After connecting
the test fixtures to the cables, the delay of the fixtures is removed by the auto port
extension function.
5.3.2.1. ECal Calibration
Calibration for the frequency domain measurement is performed from the ENA soft keys.
The 4-port ECal Module (i.e. N4431B) is necessary for the calibration procedure.
1. Press Channel Next key to select Channel 2.
2. Connect all test cables to the ECal Module.
3. Press Cal > ECal > 4-Port Cal.
5.3.2.2. Auto Port Extension
1. Connect the test fixtures to the test cables. Do not connect the DUT to the test
fixture (the fixture end is left open).
2. Press Cal > Port Extension > Auto Port Extension > Select Ports and check all ports
(Port 1 to Port 4).
3. Press Cal > Port Extension > Auto Port Extension > Measure Open and select All to
perform auto port extension.

Keysight Technologies MOI for BroadR-Reach Link Segment Tests
5.4. Measurement
The time-domain and frequency-domain measurement procedure is detailed in this
section.
There is no FEXT or NEXT as BroadR-Reach is a one-pair solution. When multiple cable
pairs are bundled, the alien crosstalk (ANEXT/AFEXT) is an interference source. In order
to limit the noise for a 6-pair bundle UTP cable, the Power Sum Alien NEXT (PSANEXT)
and Power Sum Alien Attenuation to Crosstalk Ratio Far End (PSAACRF) is specified. For
alien crosstalk measurements, the DUT is the victim cable and the other 5-pairs of cables
are the aggressor cables. The 6-pair bundle should be connected to the A+/A-, B+/B-,
C+/C-, D+/D-, E+/E-, and F+/F- differential pairs of the test fixtures respectively.
5.4.1. Differential Characteristic Impedance
1. Connect the DUT to the ENA (Figure 5-1).

near end crosstalk (PSANEXT) is specified. The PSANEXT measurement procedure is
detailed in this section. The DUT (TF1 A+/A-) is the victim cable and the other 5 cables
are the aggressors (TF1 B+/B-, C+/C-, D+/D-, E+/E-, F+/F-).

5.4.6. Power Sum Alien Attenuation to Crosstalk Ratio Far End (PSAACRF)
Power Sum Alien Attenuation to Crosstalk Ratio Far End (PSAACRF) is specified to limit
the crosstalk at the far end of the 6-pair bundled cable. Far-end crosstalk (FEXT) is noise
that appears at the far end of the victim cable (DUT) which is coupled from other
aggressor cables. The ELFEXT is equal to FEXT minus the insertion loss of the victim
cable (DUT). To limit the total FEXT coupled into the cable, the PSAACRF is specified as
the power sum of the individual ELFEXT aggressors. The measurement result of ELFEXT of
each aggressor cable is used to calculate PSAACRF.
16
Keysight Technologies MOI for BroadR-Reach Link Segment Tests
The PSAACRF measurement procedure is detailed in this section. The DUT (connected to
A+/A- pair of test fixtures) is the victim cable and the other 5 cables are the aggressors
(connected to B+/B-, C+/C-, D+/D-, E+/E-, and F+/F- pairs of the test fixtures). Because
the insertion loss result is required for calculating EFLEXT, the insertion loss
measurement (5.4.2) should be performed before the PSAACRF measurement.
