  • Page 47: E6640A Calibration Status

    E6640A. There isn’t a single instrument-level calibration (or calibration due-date) that covers the E6640A as a whole and all of the TRX modules (and the Reference module) within it. Each module is calibrated independently, and not necessarily at the same time that the others in the test set are calibrated.

  • Page 48: Certificates Of Calibration

    The EXM is a scalable test set and can be purchased with 1 to 4 TRX modules. The TRX modules, along with the Reference module (supplied with each E6640A), are the only items that require calibration, and therefore they are the only items supplied with a CoC and calibration sticker at shipment.
  • Page 49 Operating Tasks To summarize: calibration of the E6640A is not done at the instrument level, but an E6640A is fully calibrated when all of the modules (Reference module and TRX modules) are calibrated. At initial shipment, this information is provided in the yellow envelope supplied with each unit.

    Operating Tasks Launch XSA On bootup, the E6640A opens an XSA application window for each TRX which is (1) installed and (2) enabled in the TRX Configurator described above. If you have closed any of the XSA application windows, you can reopen them without rebooting, by clicking the Launch XSA icon.

  • Page 52: Port Configuration

    Operating Tasks Port Configuration Any of the TRXs four RF ports can be configured as an input port (accepting a signal to be analyzed) or as an output port (providing an RF stimulus). Two of the ports (RFIO 1 and RFIO 2) can also be used in full-duplex mode (that is, with a single port used for both input and output simultaneously).

    Operating Tasks For 3x3 MIMO , the RFIO 1 port (a full-duplex port) captures the data stream from the first antenna port of the DUT. The other full-duplex port, RFIO 2, captures the data stream from the second antenna port of the DUT. One of the half-duplex ports, RF3 I|O or RF4 I|O, captures the data stream from the third antenna port of the DUT.

    Operating Tasks 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. For MIMO Modulation Analysis, two or more measurement data streams are captured simultaneously, by two or more separate TRXs in the EXM test set.

    Operating Tasks Source Settings for MIMO Unlike measurement settings, which are made only to the primary TRX and applied to the others, source settings are made separately for each TRX, and cannot be made from the primary TRX alone. However, when the measurement is run, the primary TRX communicates with the other TRXs to ensure that they begin playing ARB files simultaneously.

    Test Set Operating System Keysight Licensing Options Keysight test sets use three licensing types: Fixed Perpetual, Transportable Perpetual, and Trial. Fixed Perpetual licenses are also required to enable hardware options. Fixed Perpetual Fixed Perpetual licenses are the traditional license type (Fixed) with the same duration (Perpetual) that have been available for all features since the Keysight X-Series introductions.

    Test Set Operating System Time-Limited Licenses (Trial Licenses) Trial licenses are available so that you may try applications before you buy the full applications. These licenses are time limited for a 14 day period, and are restricted to one trial for an individual application per instrument. The restriction is enforced through the license redemption process of the Keysight Software Manager (KSM) system.
