5.2. Instrument Setup
This section describes the procedures for recalling the state file and VBA macro that support
the instrument setup. Download "E5071C-TDR Test Package for MIPI D-PHY Tx/Rx
Devices" from www.keysight.com/find/ena-tdr_dphy-txrx.
Extract the zip file and transfer the extracted files to the instrument with a USB flash
memory. For manual measurement settings, refer to 6 Appendix.


5.2.1. Recalling State File
1. If TDR setup wizard appears, click Close button on the wizard.
2. Open Setup tab (item1).
3. Click Advanced Mode (item2).




4. A dialog box appears requesting for confirmation. Then click Yes. (Clear the check box
for "Use Advanced Calibration Methods")




5. Click File (item3) and select Recall State to open the Recall State dialog box.
6. Specify the folder and appropriate state file name, and click Open.
E5071C Test Set Option State File Name
240/245/260/265/280/285/440/445/460/465/480/485 MIPI_D-PHYv1.1_TxRx_24x-48x.tdr
