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.

Required Test Equipment

• Agilent 3458A Option 002 digital multimeter
