    "A Conceptual Model for the Reflection Measurements of a Vector Network Analyzer System and its Practical Application" - Abstract - "We present
    the gradual building of our conceptual model for the reflection
    measurements of a VNA Vector Network Analyzer System. In this way, we
    reveal the fundamental idea behind this kind of measurements and prepare
    the studier for a deeper comprehension of this subject. Moreover, since
    this abstract model is exclusively based on technical specifications
    supplied by the manufacturers of system components, it is directly
    applicable in practice. To demonstrate this fact, we use a specific VNA
    System to compute and draw both the frequency dependent systematic error parameters of it and of the reflection coefficient and input impedance
    of a particular antenna we constructed and measured by using it." -

    We got a 6 GHz nanoVNA from Amazon recently. $300.

    It seemed to be pretty simple.

    The difference between a -50 dBm noise floor and -100 dBm noise floor at
    6 GHz is about $49,700 give or take

    I have the 1.5 GHz SEESI nanoVNA clone which seems OK for crude log mag measurements up to its claimed bandwidth but the phase response sucks
    much above 1 GHz:

    This the unwrapped phase of S21 with about 500p of port extension, and a
    100mm length of microstrip on FR4 as the DUT.

    We just want to make some S21 and S11 magnitude graphs to put in some
    manuals. The RF boys expect that. You know, the guys with slide rules
    and pocket protectors.
