    Quick-Start About the Test Set About the Test Set The E6640A EXM Wireless Test set contains one to four Keysight M943xA TRXs. The specific TRX model number is dependent on the options and applications ordered with the test set: — M9432A (Option 2FD) has 2 half-duplex and 2 full-duplex ports.

  • Page 13: Elements Of The Trx

    Quick-Start About the Test Set Elements of the TRX Each TRX contains the full set of hardware elements illustrated below. Two separate examples are shown, for models M9432A (Option 2FD) and M9433A (Option 4FD). Figure 1-1 TRX elements Each TRX is run by its own instance of the XSA firmware application. A fully loaded test set shows four independent XSA windows on its monitor display.
