About the Test Set
The E6640A EXM Wireless Test set contains one to four Agilent M9430A TRXs. Each
TRX contains the full set of hardware elements illustrated below, and 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).
The TRX includes a signal analyzer and a signal source, both of which interface with the
front panel of the test set through an input/output matrix, and each of which is controlled
by an independent list sequencer (the two sequencers exchange trigger signals to
coordinate their operations). The input/output matrix is illustrated below. Ports RFIO 1
and RFIO2 are full-duplex ports (simultaneously inputs and outputs). Ports RF3 I|O and
RF4 I|O can be inputs or outputs, but not simultaneously. See also: “TRX Selection" on
page 18,“Port Configuration" on page 24.
