AC Flatness Adjustment Procedure - 10 MHz Filter (cont’d)Adjustment Procedure
(cont’d)
NOTE Rev A.02.00 (use the *IDN? command to determine the firmware revision)
allows the 10 MHz filter to be replaced with a filter that has a lower cutoff
frequency (the 10 MHz filter must be replaced at the factory). If the 10
MHz filter has been replaced, change the value for Max_freq in line 570 of
the example program to the new cutoff frequency. Changing Max_freq may
change the constants that are sent with the CAL:DATA:FILT command in step
3 (see SUB Load_magic_num).
4. Transfer the calibration co nstants to the AFG in arbitrary block data
format:
CAL:DATA:AC2 <data > Transfer cal constants
NOTE See SUB Adj_flat in the example program to see how step 4 is performe d in
Agilent BASIC.
