Clicking on the measurement tab at the upper left corner of the display opens the Mode/Measurement/View Selector, which you can use to select a particular kind of measurement.
  • Page 60 Operating Tasks Receiver Setup Most measurement settings are made from the menus, which can be accessed by selecting the dropdown button near the upper right of the display. Figure 5-4 Accessing Menus Selecting a menu from the dropdown list displays the menu selections (usually the selections are indented under multiple tabs shown at the right).
  • Page 61 Operating Tasks Receiver Setup For example, the Amplitude menu has three tabs; the selections under the Y Scale and Range tabs are shown below. Figure 5-5 Measurement Menus Getting Started Guide...
  • Page 62 Operating Tasks Receiver Setup Although some menu choices involve only a simple selection (On | Off) or a value to be entered (17 GHz), some choices cause a more elaborate selection screen to appear in the display. In the example illustrated below, Trigger > Trigger Settings Diagram opens an interactive display (the trigger source can be changed from Free Run to Ext 1 by clicking on the graphic).
  • Page 63 Operating Tasks Receiver Setup Another type of complex screen which some menu selections open is a configuration window such as the Meas Setup Summary Table, which gathers together multiple settings on one screen to make it easier to review them. Figure 5-7 Meas Setup Summary Table The menu choices are different for each measurement.

  • Page 64: Source Setup

    Operating Tasks Source Setup Source Setup The source function of the E6680A relates to generation of test signals to be transmitted to the DUT. (Not all measurement scenarios require these signals, but many do.) Most source settings are made from the Input/Output > RF Source menu, illustrated below.
  • Page 65 Operating Tasks Source Setup The Modulation Setup > ARB Setup window can be used to configure various functions of the arbitrary waveform generator. Figure 5-9 ARB Setup Window Getting Started Guide...
  • Page 66 Operating Tasks Source Setup Often the source will employ a user-defined waveform file for modulation (typically such a file would be created in Keysight Signal Studio software). To load a waveform file that is saved in a location on the disk drive, click the File icon at the bottom of the screen, and click the Recall icon which appears.

  • Page 67: Port Configuration

    Operating Tasks Port Configuration Port Configuration Each TRX unit has its own analyzer and RF source; these communicate with a set of eight RFIO ports through the RF interface matrix illustrated below. Each RFIO port can be an input port (accepting a signal to be analyzed), as an output port (providing an RF stimulus), or as a full-duplex port (doing both).

  • Page 68: Port Usage

    Operating Tasks Port Configuration Port usage Because the RF source sends signals to the ports through splitters, while the analyzer receives signals from the ports through a switch, the same signal can be sent simultaneously to as many as four ports, while only one port at a time can send back a signal to the analyzer.
  • Page 69 Operating Tasks Port Configuration Port combinations for paired ports For any port pair (7/4, 6/1, 2/5, or 3/8), the following rules apply: — If one port is used to transmit, the other can be used only to receive. — If one port is used in full duplex mode (simultaneous transmit/receive), the other port is unavailable for use, because all the resources of the pair are assigned to the full duplex port.
  • Page 70 Operating Tasks Port Configuration Setting input and output ports To set the Tx (RF Output Port), go to the menu Input/Output > RF Source menu, and select the port from the RF Output Port dropdown list. To set the Rx (RF Input Port), go to the menu Input/Output > Input menu, and select the port from the RF Input Port dropdown list.

  • Page 71: Scpi Commands For Port Setup

    Operating Tasks Port Configuration SCPI commands for port setup Input port command The SCPI command for setting an input port is: :FEED:RF:PORT:INP RFIO{n} The value of n can be 1 through 8. For full duplex mode, set the same port as both input and output.

  • Page 78: Configuration Examples (Switched Mimo)

    Operating Tasks Port Configuration Configuration Examples (Switched MIMO) For WLAN modulation accuracy measurements, a form of MIMO measurement can be made with a single TRX, using a time-division multiplexing process. The same source/analyzer pair within the TRX switches between the antenna ports of the Device Under Test.
  • Page 79 Operating Tasks Port Configuration For 3x3 MIMO, the RFIO 2, RFIO 4, and RFIO 6 ports capture the data stream from the first, second, and third antenna ports of the DUT. Figure 5-22 3X3 switched MIMO connections For 3x3 switched MIMO in Sequence Analyzer mode, three separate acquisitions are used for the three separate ports, and must be integrated.

  • Page 80: Configuration Examples (True Mimo)

    Operating Tasks Port Configuration Configuration Examples (True MIMO) In WLAN mode, True MIMO (simultaneous rather than switched MIMO) is supported for the MIMO Modulation Analysis measurement. (This functionality is not available in Sequence Analyzer mode.) Setting up this type of measurement requires configuration of two separate TRXs.
  • Page 81 Operating Tasks Port Configuration Here is an example of 3x3 MIMO: Figure 5-24 3X3 true MIMO connections In the example setup shown here, TRX 1 runs the MIMO Modulation Analysis measurement, and is also configured to control TRX 2 and 3, which collect the second and third data streams.
