34 Keysight N5990A MIPI M-PHY Receiver Test User Guide2 N5990A M-PHY StationOscilloscope BandwidthAutoIf the Auto option is selected, Keysight discovers the maximum supportedoscilloscope bandwidth automatically and adjusts to the recommendedvalue for each gear. Firmware version 5.20 or above is required for thispurpose.ManualIf the oscilloscope firmware is below version 5.20, it can be complicated forKeysight to find the maximum oscilloscope bandwidth automatically. Toavoid this situation, select the Manual option to set the desired bandwidthmanually.Once the M-PHY station is configured, you must set the InstrumentAddress. An example for the instrument configuration is as shown below(see Figure 8).Figure 8 M-PHY Instrument Configuration WindowAfter the installation process, all instruments are configured by default inOffline mode. In this simulation mode, the hardware does not need to bephysically connected to the test controller PC. N5990A cannot connect toany instrument in this mode. In order to control the instruments that areconnected to the PC, the instrument address must be entered. Theaddress depends on the bus type used for the connection, for example,GPIB (General Purpose Interface Bus) or LAN (Local Area Network). Most
