Claim 0:
1. A radio frequency (RF) load-pull tuner comprising:
a slotted coaxial airline having a test port, an idle port, a cylindrical center conductor, and two remotely controlled mobile carriages, carriage #1 and carriage #2, both moving along the slotted airline, two dielectric toroid tuning probes, toroid tuning probe #1 and toroid tuning probe #2, having associated thicknesses T1 and T2, traversed axially by the center conductor, riding on the center conductor and sliding inside and along the slotted coaxial airline,
and
an RF energy-absorbing sliver insertable into the slotted coaxial airline,
wherein
the carriage #1 controls the toroid tuning probe #1 and carriage #2 controls the toroid tuning probe #2,
and wherein
the RF energy-absorbing sliver is placed between the test port and the toroid tuning probe which is closest to the test port;
and wherein
the carriage #1 positions the toroid tuning probe #1 at a distance X1 from the test port equal or greater than the furthest extension A of the RF energy-absorbing sliver away from the test port, and the carriage #2 positions the toroid tuning probe #2 at a distance X2 from the test port equal or greater than the distance X1 of the toroid tuning probe #1 from the test port plus the thickness T1 of the toroid tuning probe #1.
