Agilent 8719ES, 8720ES, or 8722ES Option 012
Option 012 adds RF loops that provide direct access
to the A and B samplers in the port 1 and port 2
receivers. This allows transmission measurements
that bypass the receiver coupler for improved signal-
to-noise and sensitivity. The system is capable of
antenna measurements to –110 dBm at 40 GHz,
and filter rejection measurements to 120 dB. Use
of multiple antennae provides improved signal-to-
noise for free-space transmission and reflection
measurements. The RF loops can also be used to
integrate components into the test set. Adding a
20 dB attenuator increases the test port 0.1 dB com-
pression level to +30 dBm. With front panel jumpers
installed, the system operates as a standard system
and meets standard instrument specifications.
