Calibration Commands (cont’d)
• CALibration:DATA:FILTer <block> transfers the two calibration
constants that are used to determine the frequency points that will be
calibrated for the 10 MHz filter. The query form returns the current
constants in IEEE-488.2 definite block data format. See the AC
Flatness Adjustment procedure for the 10 MHz filter for more
information on the use of this command.
• CALibration:DATA:SKEW <data> transfers the calibration
constant that is used by the skew DAC to synchronize the AFG’s
DAC’s. The query form returns the current constant in IEEE-488.2
definite block data format. See the Skew DAC Adjustment procedure
for more information on the use of this command.
NOTE
The CAL:DATA:FILT and CAL:DATA:SKEW commands are available only
on units with firmware rev A.02.00 or higher (use the *IDN? command to
determine the AFG’s firmware revision).
• CALibration:STATe:AC <state> enables or disables AC
corrections using the calibration constants. If <state> is ON,
corrections will be used. If <state> is OFF, corrections will not be
used.
• CALibration:STATe:DC <state> enables or disables DC
corrections using the calibration constants. If <state> is ON,
corrections will be used. If <state> is OFF, corrections will not be
used.
• CALibration:STATe <state> enables or disables both AC and DC
corrections using the calibration constants. If <state> is ON,
corrections will be used. If <state> is OFF, corrections will not be
used.
• *PUD <data>stores the specified data in non-volatile "protected
user data" memory. The data must be sent in IEEE-488.2 definite or
indefinite block format. The query form (*PUD?) returns the
current protected user data in IEEE-488.2 definite block format.
