Setting The Source Delay; Saving Setups - Keithley 2450 Reference Manual

Section 2: General operation

Setting the source delay

Using the front panel:
1. Press FUNCTION and set the source and measurement function.
2. Press the MENU key.
3. Under Source, select Settings.
4. Select the button next to Source Delay and enter a value.
5. Click OK.
Using SCPI commands:
To set the source delay, set the command to a value. For example, to set the delay to 2 seconds,
send:
SOURce:CURRent:DELay 2
To set an automatic source delay, send the command:
:SOURce:CURRent:DELay:AUTO ON
To set these commands for a voltage source, replace CURRent with VOLTage.
Using TSP commands:
To set a specific value, set the source function and send the command smu.source.delay =
sDelay where sDelay is the delay in seconds. For example, to set a 0.5 s delay, send the
command:
smu.source.delay = .5
To set an automatic source delay, send the command:
smu.source.autodelay = smu.ON
To turn off the automatic source delay, send the command:
smu.source.autodelay = smu.OFF

Saving setups

You can save the present settings and any source or measure configuration lists that you have
defined for the Model 2450 to internal memory or an external USB flash drive.
After the settings are saved, you can recall the settings. You can also set them to be the default
settings on power up.
If you are using TSP commands, saved setups are scripts and can be added, modified, and deleted
like any other script. See
working with scripts.
