Also available in the M197x series are the M1971 series USB Mixers, which provide
additional inputs and outputs for special functionality as described below. These
mixers have multiple signal paths which allow them to function in three different
states:
–
Normal, in which the mixer functions as a classic external mixer with a single
conversion:
–
Dual Conversion, which gives you a wider image-free range. In Dual Conversion,
the first conversion is to a higher IF frequency and you provide a 10 MHz signal
to which an internal PLL is locked, to effect a second downconversion:
–
Aux Equipment, wherein the first mixer output drives an output connector on the
mixer and the instrument is out of the circuit:
External Mixing is only supported in certain Modes and Measurements in the X-
Series, as shown in the table below. When External Mixer is selected in a
