Execute SCPI commands when not in Model 2400 emulation
mode
You can execute SCPI commands when not in Model 2400 emulation mode. To accomplish this,
send the Initialize2400() command once and then send the Execute2400() command with
the SCPI command as a parameter in quotes. For example, to execute the SCPI
command :SOURCE:VOLTAGE 1, send Execute2400(":SOURCE:VOLTAGE 1"). If quotes are
needed in the SCPI command, use single quotes or use '\' as an escape character. For example,
send one of the following commands to execute the SCPI command :SENSE:FUNCTION
"VOLT:DC":
Execute2400(":sens:func 'VOLT:DC'")
Execute2400(":sens:func \"VOLT:DC\"")
To return to the Model 2400 emulation mode, send the Engine2400() command. After returning to
the Model 2400 emulation mode, you must execute a *RST before running any further commands.
Model 2400 compatibility
This section provides information on programming the 2600B in Model 2400 emulation mode. The
information provided includes details of general compatibility and tables that contain listings of the not
supported, partially supported, and fully supported commands.
General compatibility
Observe the following details when operating the 2600B in Model 2400 emulation mode.
Busy signal
As in a non-emulated Model 2400, the BUSY signal is active from the point that a start-of-test (SOT)
signal is received until all measurements, limit testing, and digital I/O operations have completed. To
use a BUSY signal in a non-emulated Model 2400, the binning control must be set to END. If the
trigger count is set to a value less than the number of points in the source memory sweep, the BUSY
signal indefinitely stays in the busy state. When the 2600B is in Model 2400 emulation mode, the
BUSY signal works in either binning control modes (END or IMM) if one or more of the Calculate2
limit tests are enabled and is not in the busy state indefinitely.
Source autodelay
While in Model 2400 emulation mode, when the source auto delay feature is enabled, the 2600B
source delay is used and is set to automatic delay (smua.source.delay = smua.DELAY_AUTO).
