Focus manufactures Manual Microwave Tuners since 1997. They are available with single probe (limited bandwidth) and double probes (extended bandwidth). They are also available as MHMT (Manual tuners with a harmonic resonator for independent control of one harmonic frequency). Positioning repeatability is excellent, because the probe and slabline technology are the same as used in the automatic high-end tuners. MMT's are available from 400MHz to 50GHz. The presented model (with enhanced positioning control) has two probes covering from 600 MHz to 18 GHz.
