FAULT?
Returns the error code number of an error that has occurred. The command
may be entered when the previous command did not do what it was meant
to do.
For example, if a value for current output is entered that is bigger than the
supported range (0-24mA) FAULT? Would return:
103 which is the code number for an entry over range.
Refer to the Error Codes table for more information on error code numbers.
FREQ_LEVEL
Sets the amplitude of the wave used in the Frequency Out and Pulse
modes. The range for amplitude entered may be found in the Specifications
section.
For example:
FREQ_LEVEL 5 V sets the amplitude at 5Vpp.
FREQ_LEVEL?
Returns the amplitude of the wave used in Frequency Out and Pulse
modes.
FREQ_LEVEL? with the above example would return:
5.000000E+00, V 
FREQ_TYPE
When in frequency mode, sets the calibrator to output a continuous wave
(Frequency Out), or a pulse train. To set the calibrator to continuous wave
enter CONT after the command. To set the calibrator to pulse enter PULSE
after the command. For example:
FREQ_TYPE CONT will set the calibrator to FREQ OUT.
Note: This command does not put the calibrator in frequency mode. Use
the OUT command to put the calibrator in frequency mode.
FREQ_TYPE?
Tells whether calibrator is sourcing a pulse or a continuous wave. The
command will return CONT if the calibrator is in FREQ OUT mode, and
PULSE if the calibrator is in PULSE mode.
