Overview
Multiple source control is an application to independently control the internal source and receiver as well as up to four external synthesizers.
Since there are no constraints on frequency linkage (other than the ranges the hardware is capable of), a wide array of mixer, multiplier, converter and other specialized measurements can be performed. Some examples include:
• Mixers (up and down conversion, many conversion stages)
• Frequency multipliers
• Dividers
• Harmonic measurements (including the ability to look at fractional harmonics)
• IMD measurements
• Very high frequency measurements where the source and LO are generated externally
Since the interface is extremely flexible, this procedure also works for broadband/mm-Wave measurements for applications where the broadband/mm-Wave interface is too limiting.
