APS-1102 LabVIEW Driver Manual
1.1 General
The APS-1102_LabView driver.llb is a LabVIEW measuring instrument driver for the GW Instek
APS-1102 programmable AC/DC power source.
This driver allows application configuration without bothering with details of the APS-1102 program
messages.
* During creation of this driver, operation under the following environments was confirmed:
OS: Windows 2000 and Windows XP
LabVIEW: Ver. 6.1, 7.1, 8.0
VISA: Ver. 3.5 or higher
With some versions of LabVIEW, vi may automatically be changed for inter-version consistency. In
such a case, follow the instructions shown on the computer screen.

APS-1102 LabVIEW Driver Manual
2.1 About vi
Error input and output are provided in each APS-1102 operation vi. Error cluster chains are
generated by connecting an error output to the error input of the next vi. This allows a natural error
I/O for the LabVIEW data flow architecture to be obtained. An application can monitor the
intermediate error status as required.
APS-1102 operation vi, except for Close, has a VISA session input and a duplicated VISA session
output. Use chain connections for these as well. Close has a VISA session input only, so the
application forms a chain from Initialize to Close.
Vi, of which input items contain Read, can output the contents set in the APS-1102. When
outputting, set the bool controller to ON (True). The default setting is OFF (False).
Parentheses ( ) at the end of an item name indicate default setting. For example, “Read (F)”
indicates that the default setting is “False”. In the same way, square brackets [ ] for numerical
controllers or the display device indicate quantity units.
See the sample application for actual connections.
The following sections describe error I/O, VISA session and I/O terminals except Read.

2.4 VISA Initialization
GW APS-1102 Initialize.vi
Performs initialization. Internally executes the APS-1102 Reset to return the various settings to
those at memory initialization.
<Input>
IDCheck
Specify whether to check the ID. The default setting is “Yes (True)”.
Reset
Specify whether to execute resetting. The default setting is “Yes (True)”.
2.5 VISA Close
GW APS-1102 Close.vi
Stops using the APS-1102 operation vi and closes the VISA session.

2.6 SOURce Subsystem
GW APS-1102 SOUR Curr Ave.vi
This sets the upper limit of the output average current.
<Input>
Average_Rn100V [A]
This sets the upper limit of the output average current in the 100 V range. The default
setting is “10.5”.
Average_Rn200V [A]
This sets the upper limit of the output average current in the 200 V range. The default
setting is “5.3”.
Rn_set
This specifies the range to be set. The default setting is “100 V (False)”.
<Output>
Output [A]
When Read = True, outputs the upper limit of output average current set for the APS-1102.
When Read = False, “99.9” is set.
GW APS-1102 SOUR Curr High.vi
This sets the upper limit of the output peak current (positive polarity).
<Input>
High_Rn100V [A]
This sets the upper limit of the output peak current (positive polarity) in the 100 V range.
The default setting is “42.0”.
High _Rn200V [A]
This sets the upper limit of the output peak current (positive polarity) in the 200 V range.
The default setting is “21.0”.
Rn_set
This specifies the range to be set. The default setting is “100 V (False)”.
<Output>
Output[A]
When Read = True, outputs the upper limit of output peak current (positive polarity) set for
the APS-1102. When Read = False, “99.9” is set.

This sets the upper limit of the output peak current (negative polarity).
<Input>
Low_Rn100V [A]
This sets the upper limit of the output peak current (negative polarity) in the 100 V range.
The default setting is “–42.0”.
