Differences between E7515B and E7515E
The E7515B model of the UXM 5G differs from the economy version (E7515E)
in that it includes circuit boards which the economy version omits., and it omits
some internal circuit boards. Consequently, it has some limitations on
functionality, and particularly on RF port usage, which are explained here for
the benefit of users who may be familiar with the UXM 5G in its E7515B
version.
The eight Tx/Rx ports on the front panel (RF 1-8) communicate with the
instrument’s interior source and analyzer by way of the RFIO board. Although
the RFIO board is the essentially the same as the E7515E version, it must
interface with the Mixed Signal and Radio Frequency boards, which in the case
are different. The E7515B contains two Mixed Signal Boards (MSB 1 and MSB
2) rather than one, and also two Radio Frequency Boards (RFB 1 and RFB 2)
rather than one. This expands the capacity of the RFIO board to exchange
signals with the source and analyzer.
