Over the bus, send the 'SOUR:FUNC VOLT' command to output voltage or the 'SOUR:FUNC CURR' to output current. Press the …70931 Speed: What is the difference between 'source delay' and 'trigger delay'?
The trigger delay occurs between the trigger event (for example, the Trigger Link or digital input trigger signal) and turning on the SourceMeter instrument output. The source delay occurs after the output is turned on and before the measurement is …70901 Compliance: What does it mean when the CMPL (compliance) blinks on the front panel?
It means the clamping compliance value that is programmed is reached. To stop hitting the compliance limit, verify that your device is not defective and the programmed limit is correct or just increase the compliance limit to a level where the limit …70941 Sweep: Which instrument parameters are saved in each Source Memory location?
Not every setting of the instrument is saved in memory for a sweep. Certain settings affect the instrument and can't be changed from point to point in the sweep. Refer to the SourceMeter Series User Manual for a well-defined list of settings (shown …70976 Remote Operation: How can I program a SourceMeter Instrument to Measure Resistance?
How can I program a SourceMeter Instrument to Measure Resistance? The MANUAL resistance measuring mode of the Model 2400 allows the user to select a source of voltage or a source of current. If current is sourced then voltage is measured. If voltage …69606 Do you have a SCPI Sequence for 100V @ 10A on Model 2461 SMU?

What is the difference between Auto and Manual mode for resistance in the Model 2400? The AUTO resistance measuring mode of the Model 2400 configures the unit to source current, measure voltage and calculate resistance. The magnitude of the …71671 Sweep: How many discrete points can be programmed into a sweep?
The SourceMeter instruments can do sweeps of up to 2500 points when performing linear, logarithmic, or custom sweeps. These sweeps output only voltage or current, not a mix of both. These types of sweeps also use the same source delay (soak time) and …70971 Remote Operation: Can I use GPIB cards from Agilent with Keithley's Instrument Drivers?
Can I use GPIB cards from Agilent with Keithley's Instrument Drivers? Yes, so long as the instrument driver makes use of VISA for instrument communication. This will be true of any instrument driver that is IVI or VXI/PnP based. This applies to an …71456 Sweep: Can I use an external trigger to stop a SourceMeter sweep?
Can I use an external trigger to stop a SourceMeter sweep? The SourceMeter trigger model does not have provisions for stopping a sweep using a trigger signal.

Answer: The specified output impedance of …69601 Sweep: Is it possible to send a command to the SourceMeter that will interrupt the sweep?
Is it possible to send a command to the SourceMeter that will interrupt the sweep in progress? There are several commands you can use to interrupt a sweep. You can send a SCPI abort (:ABORT) command, which will abort the sweep and return the …71926 Specs: How does the 2400-LV differ from the 2400?
The Model 2400-LV SourceMeter is a reduced capability version of the Model 2400 not intended for general release. Designed for a narrow range of applications, the 2400-LV eliminates the high voltage supplies internal to the instrument, thereby …69596 Speed: In what circumstances might I need to use a measurement speed other than Normal?
It depends. There is always a trade-off between speed of the measurements and their accuracy. The accuracy specifications for the SourceMeter family are stated in terms of an NPLC setting of 1 (in other words, Normal speed). The Normal speed setting …70906 Speed: How fast can the 2400 series output a pulse?
How fast can the 2400 series output a pulse? The Models 2400, 2410, 2420, 2425, and 2440 can be configured to output a voltage pulse in approximately 360 microseconds or a current pulse in 640 microseconds. The Model 2430 can be configured to …69631 Remote Operation: Does it matter if I use upper or lower case characters when sending commands?
No, the case used doesn't matter. The 'SOUR:DEL 0.01' command and the 'sour:del 0.01' or 'Sour:Del 0.01' commands are the same.70961 Remote Operation: What are VXIPnP Drivers?
72036 Ohms: Which SourceMeter instrument do you recommend for four-point probe measurement techniques?
All Keithley Series 2400 SourceMeter instruments, as well as the Model 6430 Sub-Femtoamp Remote SourceMeter, are capable of making four-point probe measurements. That is, along with the input/output HI and LOW terminals, there is a corresponding …70186 Speed: What factors affect the speed of a SourceMeter?
What factors affect the speed of a SourceMeter? The execution time of Single measurements, Sweeps (linear or log) or custom sweeps via a source memory list for Model 2400 series can be influenced by several factors. Source-Delay-Measure Cycle …69636 Ohms: What type solder can I use when I cannot make direct threaded connections to my sample?
In the past, cadmium solder was used because it had a low thermal property. Unfortunately, cadmium solder has been determined to be toxic and its use has been eliminated. Silver type solder is about the only solder that is commercially available …71316 Remote Operation: What Front Panel Settings are Required to use the VXIPnP drivers for SourceMeter?
What Front Panel Settings are Required to use the VXI PnP drivers for the SourceMeter Instruments? Selection and configuration of GPIB or RS-232 communication is important. Both are supported by the VXI PnP driver, however, the instrument must be …69611 Specs: How does a SourceMeter instrument differ from a DMM?
Traditional DMMs generally only measure the result of a certain physical phenomena, such as AC voltage, DC current, resistance, frequency, or temperature. The SourceMeter products have built-in sources that can source voltage or current to the device …70881 Compliance: What does it mean when the units for the compliance value blink on the front panel?
The instrument is in range compliance. Generally, this occurs when the measurement range is less than the programmed compliance value. If the compliance limit is set to 100mA and the instrument is set to the 10mA measurement range, an output value of …70946 Ohms: How do I select 4-wire ohms measurement?
Over the front panel, select the following: CONFIG button ohms button SENSE-MODE menu selection 4-WIRE menu selection ENTER button. Via the bus, send the 'SYST:RSEN ON' command. Once you've selected this function successfully, the '4W' annunciator …70926 Remote Operation: Why do I get a VISA timeout (BFFF0015) using RS-232 with a SourceMeter?
Product(s) : SourceMeter Instruments: 2400, 2410, 2420, 2425, 2430, 2440 Question : Why do I get a VISA timeout (BFFF0015) using RS-232 with a SourceMeter? Answer: When programming a SourceMeter through the VISA layer into RS …72011 Remote Operation: Which communication buses do the SourceMeter Instruments support?
All SourceMeter instruments are shipped with General Purpose Instrument Bus (GPIB) and RS-232 ports standard.70956 Feature: How do the various SourceMeter instruments differ from each other?
All instruments in the SourceMeter product line share much of the same functionality and are programmed and controlled similarly. The only functional difference is the dynamic output range for each.
