Hi
I'm calibrating a 8563E spectrum and having a problem with the 10 MHz point in frequency response adjustment routine.
Any other point up to 26.5GHz is responding when the DAC are changed as called by the calibration routine.
But the 10 MHz point, the DAC can be changed but no effect on the frequency correction.
The software version is 990108.
Can anybody help?
Thanks.

13.If the firmware revision is later than 920528, perform steps 13
through 17. Otherwise, skip to step 18.
14.Press Ý until 10 MHz is displayed in the active function block.
Record the RF gain DAC value at 10 MHz.
10 MHz RF gain DAC value ______________
15.Add 67 to the 10 MHz RF gain DAC value and record as the 2 MHz
RF gain DAC value.
2 MHz RF gain DAC value ______________
16.Add 62 to the 10 MHz RF gain DAC value and record as the 6 MHz
RF gain DAC value.
6 MHz RF gain DAC value ______________
17.Press ß until 2 MHz is displayed in the active function block. Use the
DATA keys to enter the 2 MHz RF gain DAC value recorded in
step 15.
18.Press Ý until 6 MHz is displayed in the active function block. Use the
DATA keys to enter the 6 MHz RF gain DAC value recorded in
step 16.
