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 upper and lower displays. For
example if the calibrator is set to volts on the upper display, and
pressure on the lower display, FUNC? Would return:
DCV, PRESSURE
GET_CLOCK
Returns the current calibrator time and date as "yyyy/mm/dd
hh:mm:ss", for example:
2006/03/25 19:02:56
GET_SN
Returns the calibrator serial number of up to 10 digits, for example:
12345678
