25
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.
FREQ_UNIT
Sets the unit for frequency. There are three ranges of frequencies for frequency and pulse
modes, CPM (cycles per minute), Hz, and kHz. Use this command to select the right range.
For example:
FREQ_UNIT HZ sets the frequency to Hz range
FREQ_UNIT?
Returns the frequency unit currently being used by the frequency and pulse modes.
FUNC?
Returns the current mode of the display. For example if the calibrator is set to volts FUNC?
Would return:
DCV
