KV versus Frequency Calibration
Description
This calibration determines the tuning sensitivity of the synthesizer loop. To measure the sensitivity, the
tuning voltage is measured as the frequency is stepped from 500 to 1000 MHz in 10 MHz steps. At each
incremental frequency, the tuning voltage is measured (Vtune1) and again at the incremental frequency
+300 kHz (Vtune2). The sensitivity is then calculated in units of MHz/V and stored in the signal generator’s
firmware.
