BOP-VISA 010906
Reset KpBop_psReset Resets the instrument to a known state and sends initialization com-
mands to the instrument.
Self-Test KpBop_selfTest Runs the instrument's self test routine and returns the test result(s).
Error-Query KpBop_errorQuery Reads an error code from the instrument's error queue.
Error Message KpBop_errorMessage Takes the Status Code returned by the instrument driver functions,
interprets it and returns it as a user readable string.
Calibration Status On/Off KpBop_CalStatus Used to enter or exit the calibration state. To enter the calibration state
an 11-character password is required. When the instrument is shipped
from the factory the calibration password is "DEFAULT". The password
protects the instrument against unauthorized calibrations.
Calibration Mode KpBop_CalMode Allows the user to select the calibration mode (either voltage or current
calibration) and also allows selection of 0 (min) or full scale (max) cali-
bration.
Calibration Output KpBop_CalOutput Allows the user to perform the power supply calibration in both voltage
or current mode. By moving the digital to analog converter the number
of LSB's specified in the repeat count, the user can approach the 0 or
full scale value of the corresponding power supply. This is a fine adjust-
ment for the 0 or full scale value. The user can specify a repeat count
between 1 and 9 in order to avoid having to repeat sending the com-
mand
Calibration Zero KpBop_CalZero Used to zero the output of the power supply before switching from volt-
age calibration to current calibration (to allow a calibration resistor to be
connected between the power supply output terminals.
Zero Voltage Calibration Kpbop_CalVoltZero Calibrate output zero in Voltage mode.
Zero Current Calibration Kpbop_CalCurrZero Calibrate output zero in Current mode.
Volt_low Calibration
constants Kpbop_CalVLSD Read Calibration constants when unit is in low-volt calibration mode.
Volt Calibration con-
stants Kpbop_CalVSND Read Calibration constants when unit is in voltage calibration mode.
Curr_low Calibration
constants Kpbop_CalCLSD Read Calibration constants when unit is in low-current calibration
mode.
Curr_high Calibration
constants Kpbop_CalCSND Read Calibration constants when unit is in current calibration mode.
Calibration Save KpBop_CalSave Stores the calibration results in the nonvolatile calibration memory of
the instrument.
Security Code KpBop_CalCode Allows the user to change the password to prevent accidental or unau-
thorized calibrations of the instrument. The password is stored in non-
volatile memory, and does not change when power has been off or
after a reset. To change the password, the instrument must already be
in calibration status, ensuring that the user knows the current pass-
word. If the password is lost, call the factory for support.
Disable Password Kpbop_PassDis Allow user to disable the security code.
Dump Calibration Kpbop_CalDUMP Save Calibration constants in files.
Restore Calibration Kpbop_CalRestore Restore Calibration constants from files.
Close KpBop_close This function takes the instrument off-line.
