What is the difference between the two RF cables attached to the U7227A/C/F?

There is a slight change in the mechanical dimension and color for the RF cable that is attached to the USB preamplifier.

 The new RF cable is more robust and has been qualified in accordance to Keysight requirements. Due to the firm ruggedized cable, the USB preamplifier may not sit flush on a flat surface. This is normal, and does not impact the general performance of the amplifier.
