Mixer Paths (External Mixer)
Menu Path:
The drop-down menu allows you to select the external mixer path when a mixer is attached to the LO/IF port of an X-Series Signal Analyzer. The drop-down list will only enable valid path choices that apply to the current measurement hardware.
- The mixer functions as a classic external mixer with a single conversion, as shown in the example illustration:
- After a single conversion using the signal analyzer's LO signal, the converted IF signal is routed to an auxiliary output connector on the mixer instead of being routed to the signal analyzer. This makes it possible to use an E-Band mixer with instruments like Keysight Infiniium oscilloscopes.
- The signal is converted two times, providing a wider image-free range. The signal is first converted to a higher IF frequency. The signal is then downconverted using an internally PLL Phase Locked Loop is a major component in the frequency synthesizer scheme. This device provides a wide, flexible range of internal frequency dividers which allow the designer the ability to create a synthesizer to match design requirements.-locked, user-supplied 10 MHz Megahertz: A unit of frequency equal to one million hertz or cycles per second. signal, as shown in the example illustration:
