Amplitude Accuracy of Calibrated ERASynth

Open-loop Calibration:

Erkin has developed a search algorithm for finding the optimal attenuator settings for a given power level. He used U2001A USB power-meter by Agilent for calibrating the prototype. This power-meter works from 10MHz to 6GHz and measures power levels between -60 to +20 dBm. We have ordered a new power-meter that will measure up to 26.5 GHz, it is on its way to Turkey. Once we get our new power-meter, we will be able to calibration beyond 6 GHz. After the calibration, amplitude uncertainty is below 0.5 dB and setting resolution is 0.1 dB.

Quick demo of REF IN:

We also show a quick demo of REF input, showing a 1 GHz signal move on the spectrum analyzer when REF input is switched between internal and external.
