Install the GPIB driver software Check the documentation for your GPIB controller for information about where to acquire drivers. Keithley Instruments also recommends that you check the website of the GPIB controller for the latest version of drivers or software.
Page 37 They directly call the GPIB driver support libraries. For the KPCI-488LPA and KUSB-488B GPIB controller from Keithley Instruments, the configuration utility is called the KI-488 Diagnostic Tool. It is available from the Windows Start menu at Keithley Instruments > KI-488 > KI-488 Diagnostic Tool.
Page 38 If you want to use the GPIB controller with instrument driver (such as VXIPnP or IVI) or high-level software, you must also install I/O software, which installs the VISA layer. See How to install the Keithley I/O Layer. Terminator When receiving data over the GPIB, the instrument terminates messages on any line feed character or any data byte with EOI asserted (line feed with EOI asserted is also valid).
Page 39 Section 2: Installation Series 3700A System Switch/Multimeter Reference Manual The remote enable (REN) command is sent to the Series 3700A by the controller to set up the instrument for remote operation. Generally, the instrument should be placed in the remote mode before you attempt to program it over the bus.
Page 40 Keithley Instruments > KI-488 > KI-488 Diagnostic Tool. For the KUSB-488A GPIB controller from Keithley Instruments, the configuration utility is called GPIB Configuration. It is available from the Windows Start Menu at Keithley Instruments > GPIB-488 > GPIB Configuration. For National Instruments (NI ) GPIB controllers, you can use NI-MAX.

Place the instrument in the talk state by addressing it to talk with the correct talk command. TALK is off when the instrument is in the talker idle state.
Page 42 Series 3700A System Switch/Multimeter Reference Manual Section 2: Installation Overview of LAN instruments When ethernet ports became standard on computers, it was logical that instrumentation would follow. The VXI-11 protocol, which was standardized on in the early 1990s, is the standard used to emulate GPIB over ethernet.

Page 44 Section 2: Installation Instrument driver types There are several different styles of instrument drivers. Keithley Instruments provides three different instrument drivers for the Series 3700A: A native LabVIEW driver, an IVI-C driver, and an IVI-COM driver. You need to pick the style that best suits the application development environment (ADE) that you are using.
Page 45 , you can also go to the National Instruments website and search their instrument driver database. Instrument driver examples All Keithley drivers come with examples written in several programming languages that show you how to do the most common things with the instruments. ®...
Page 46: Keithley I/O Layer
Keithley I/O layer The Keithley I/O Layer (KIOL) is a software package that contains several utilities and drivers. It is mainly used as a supplement to IVI drivers or application software like Test Script Builder (TSB). The KIOL contains: •...
Page 47 If you do not have NI software installed, to use Keithley drivers or application software, you must install the KIOL. This installs a valid, licensed copy of the NI-VISA runtime to use with Keithley drivers or application software. KIOL installs a valid license for the NI-VISA Run-Time Engine only (not the full version of NI-VISA).
Page 48 VISA to malfunction. The recommended way to resolve this situation is to perform the following steps: 1. Exit the Keithley I/O Layer software when the warning message is displayed. Make note of the VISA vendor in the warning message (if any).
Page 49 8. If the pre-existing version of VISA was supplied by a vendor other than Tektronix or Keysight, we recommend that you do not reinstall it, because this will likely cause the Keithley I/O Layer software to malfunction.
Page 50: Addressing Instruments With Visa
The following sections describe the resource strings for some of the communication types that Keithley supports. Any field that has [] (square brackets) around it is optional and will revert to a default value. Addressing instruments through the LAN VISA supports two different LAN protocols, each of which has a different resource string.
Page 51 Section 2: Installation Series 3700A System Switch/Multimeter Reference Manual Addressing instruments through GPIB There are two different resource classes in VISA for the GPIB bus. INSTR is the basic class that everyone uses. It allows application software to send and receive data and commands without dealing with some low level GPIB nuances.

Page 214: Hardware Trigger Modes
(on page 11-336) Hardware trigger modes Use the hardware trigger modes to integrate Keithley Instruments and non-Keithley instruments into an efficient test system. The hardware synchronization lines are classic trigger lines. The Series 3700A contains 14 digital I/O lines and three TSP-Link synchronization lines that you can use for input or output triggering.
Page 215 Section 5: Switching and scanning Series 3700A System Switch/Multimeter Reference Manual A trigger overrun generates if an input trigger is received before the previous input trigger processes. To determine if a trigger overrun has occurred, reference the trigger overrun attributes. For additional information on the hardware trigger modes, see TSP commands (on page 11-8).
Page 216 Use the rising edge master (RisingM) trigger mode (see the figure titled "RisingM output trigger") to synchronize with non-Keithley instruments that require a high pulse. Input trigger detection is not available in this trigger mode. You can use the RisingM trigger mode to generate rising edge pulses.
Page 217 Section 5: Switching and scanning Series 3700A System Switch/Multimeter Reference Manual Output characteristics: • In addition to trigger events from other trigger objects, the digio.trigger[N].assert() and tsplink.trigger[N].assert() commands generate a low pulse that is similar to the falling edge trigger mode. Figure 89: RisingA output trigger Either edge trigger mode The either edge trigger mode generates a low pulse and detects both rising and falling edges.

IEEE-1588 is a requirement of the LXI B and C Functional Classes.
Page 224 Series 3700A System Switch/Multimeter Reference Manual Section 5: Switching and scanning UTC suffers from discontinuities because of nonperiodic adjustments known as “leap seconds." These adjustments present problems because they can make events that occurred at different periods of time appear to occur at the same time. PTP is a time standard that does not have any discontinuities and has no adjustments for local time (that is, it is not time-zone aware).

Page 313: What Is A Script
Section 10: Instrument programming Series 3700A System Switch/Multimeter Reference Manual What is a script? A script is a collection of instrument control commands and programming statements. Scripts that you create are referred to as user scripts. Your scripts can be interactive. Interactive scripts display messages on the front panel of the instrument that prompt the operator to enter parameters.
Page 314: Commands That Cannot Be Used In Scripts
To manage scripts, you can send messages to the instrument, use your own development tool or program, use Keithley Instruments Test Script Builder (TSB) software, or use TSB Embedded on the instrument's web interface. TSB and TSB Embedded are described below.
Page 315 Section 10: Instrument programming Series 3700A System Switch/Multimeter Reference Manual Named scripts A named script is a script with a unique name. You can have as many named scripts as needed in the instrument (within the limits of the memory available to the run-time environment). When a named script is loaded into the run-time environment with the loadscript or loadandrunscript commands, a global variable with the same name is created to reference the script.
Page 316 Series 3700A System Switch/Multimeter Reference Manual Section 10: Instrument programming To load a named script by sending commands: 1. Send the command loadscript scriptName, where scriptName is the name of the script. The name must be a legal Lua variable name. 2.

Page 497: Digio.trigger[N].Mode
If the programmed state of the line is low, the digio.TRIG_RISING mode behavior is similar to digio.TRIG_RISINGM. This setting should only be used if necessary for compatibility with other Keithley Instruments products. digio.TRIG_EITHER or 3 Detects rising- or falling-edge triggers as input. Asserts a TTL-low pulse for output.
Page 498: Digio.trigger[N].Overrun
Use of either digio.TRIG_SYNCHRONOUSA or digio.TRIG_SYNCHRONOUSM is preferred over digio.TRIG_SYNCHRONOUS, because digio.TRIG_SYNCHRONOUS is provided for compatibility with the digital I/O and TSP-Link triggering on other Keithley Instruments products. To control the line state, set the mode to digio.TRIG_BYPASS and use the digio.writebit() and digio.writeport() commands.

Page 906: Status Model
TSP-Link system status ............C-20 Overview Each Keithley Instruments Series 3700A provides a number of status registers and queues that are collectively referred to as the status model. Through manipulation and monitoring of these registers and queues, you can view and control various instrument events. You can include commands in your test program that can determine if a service request (SRQ) event has occurred and the cause of the event.
Page 907 Appendix C: Status model Series 3700A System Switch/Multimeter Reference Manual • Positive Transition Register (PTR) (.ptr): When a bit is set in this read-write register, it enables a 0 to 1 change in the corresponding bit of the condition register to cause the corresponding bit in the event register to be set.
Page 908: Status Model Diagrams
Series 3700A System Switch/Multimeter Reference Manual Appendix C: Status model Status model diagrams The register sets (and queues) monitor various instrument events. When an enabled event occurs in one of the five registers, it sets the associated summary bit in the Status Byte register. When a summary bit of the Status Byte is set and its corresponding enable bit is set (as programmed using status.request_enable), the MSS bit will set to indicate that an SRQ has occurred.
