Agilent 8719ES, 8720ES, and 8722ES Option 007
Agilent 8719ES, 8720ES, and 8722ES Option 085
Includes instruments with Options 012 1 and/or 089.
Option 007 replaces the standard solid-state
transfer switch with a mechanical switch to pro-
vide higher output power.
Option 085 adds internally controlled 0 to 55 dB
step attenuators (5 dB steps) in the receiver path
of both ports, an RF loop that allows the addition
of an amplifier before the transfer switch, and RF
loops after the switch that allow insertion of isola-
tors, required for measurements above 1 watt. An
internal reference channel switch is added and inter-
nal bias tees are deleted. This system is capable of
full two-port calibrated measurements to 20 watts.
Measurements up to 100 watts may be possible
using specific configurations. Option 085 includes
direct sampler access (Option 012). Option 085 is
not compatible with Option 400.
