The IF input signal to the upconverter can be supplied at any one of these
ports: the
LO/Pwr/Ctrl/IF In
port, the
IF In
port, or the bi-directional
IF In/Out
port.
The IF output signal generated by the downconverter can be routed to the
bi-directional
IF In/Out
port or the bi-directional
LO/IF Out
port.
Signal routing is controlled from the instrument to which the M1740A is
connected; the combined signal at the
LO/Pwr/Ctrl/IF In
port includes a
control signal for this purpose. It also includes a DC voltage to power the test
head.
License-based restrictions apply to various bands within the full frequency range
of the M1740A, but the licenses are issued specifically for other instruments
which interface with the M1740A (for example, theE7760B Wideband
Transceiver, which has licensed options for several different frequency bands).
