When using the DIQ application, what happens when I set the internal receiver to measure beyond the frequency range of my instrument?

While the displayed frequency range is not limited by the instrument hardware, the range of legitimate data provided from the internal receivers is. Data for frequencies beyond the instrument hardware limitations is extrapolated from the hardware’s maximum and minimum limits.

For example, when attempting to measure up to 50 GHz on a 27 GHz instrument, the data collected at 27 GHz will extend to the 50 GHz point.
