3. Waite 3-4 seconds and release both front buttons.
4. On CH1 select the highest output frequency for your generator model. Set an amplitude of 0,3-1,0 V.
5. Press “SYS” and then “More”.
6. Now on the screen you can see “Oscillator” and on display 10.000.000.000 MHz
7. Press F5 to go to frequency calibration.
8. Connect a frequency meter to CH1 output.
9. Using cursor and the dial obtain reading of the frequency meter the same as set on the generator. If measured frequency is lower – dial should be rotated CCW, if higher – CW.
After calibration press the “Dial” and then CH1 to return to normal operation.
