2. PROGRAMMER REFERENCE
2.1 VISA INSTRUMENT DRIVER FUNCTIONS
Kepco’s BOP VISA instrument driver provides programming support for Kepco’s BOP Power Supply (VISA
I/O). It contains functions for opening, configuring, taking measurements from, test, calibration and closing
the instrument. To successfully use this module, the instrument must be connected to the GPIB and the
GPIB address supplied to the initialize function must match the GPIB address of the instrument.
Table 3 lists the functions that are available.
TABLE 3. BOP VISA DRIVER FUNCTIONS
Purpose Function Name Description
INITIALIZE FUNCTION
Initialize KpBop_init Initializes the instrument and sets it to a default configuration.
APPLICATION FUNCTIONS — This class of functions contains high-level test and measurement routines. These functions call
other instrument driver functions to configure, start, and get readings from the instrument.
Set and Measure KpBop_ApplicSetMeas Used to either set and read back, or just read back the output voltage,
current and operating mode of the power supply
CONFIGURATION FUNCTIONS — This class of functions configures the instrument by setting system configuration parameters.
Get Current Range
Status Kpbop_getCurrRange Unit can operate in either auto, high or low range. The function will
return 0 for auto, 1 for high range and 4 for low range
Set Current Range Kpbop_setCurrRange Sets the current operating range (auto, high or low)
Get Voltage Range
Status Kpbop_getVoltRange Unit can operate in either auto, high or low range. The function will
return 0 for auto, 1 for high range and 4 for low range
Set Voltage Range Kpbop_setVoltRange Sets the voltage operating range (auto, high or low)
Get Minimum or Maxi-
mum Value KpBop_GetMinMaxValue Gets the minimum or the maximum output voltage, output current of the
power supply depending on the min_max switch and slide selection
position.
Set Trigger Voltage and
Current KpBop_SetTrig_Volt_Curr Sets the trigger voltage and trigger current at the same time
Set Trigger Value KpBop_SetTrigValue Sets the trigger voltage or trigger current level, depending on the switch
position.
Get Trigger Value KpBop_GetTrigValue Gets the trigger voltage or the trigger current level, depending on the
switch position.
ACTION/STATUS FUNCTIONS — This class of functions executes commands and queries. It also provides functions which allow
the user to determine the current status of the instrument.
Set Voltage and Current KpBop_Set_Volt_Curr Sets the output voltage and current at the same time.
Set Value KpBop_SetValue Sets the output voltage, the output current of the power supply,
depending on the slide selection position. The values are checked
against the maximum acceptable values for the corresponding power
supply.
Get Value KpBop_GetValue Gets the output voltage, the output current of the power supply depend-
ing on slide selection position.
Transient pulse in volt-
age mode Kpbop_TransVolt Sets the power supply to the required value for the indicated time
Transient pulse in cur-
rent mode Kpbop_TransCurr Sets the power supply to the required value for the indicated time
Clear List parameter Kpbop_ListClr Clears all the parameters of a list, set direction to UP and SEQ to
Default (DSEQ)
Count list parameter Kpbop_ListCount Sets the LIST seq to run for COUNT periods
