COMMANDS NOT SUPPORTED

C-SCPI does not support the commands listed. However, these commands are still supported in the Command Module version.

Macro commands not supported: MEM:DEL:MACR, *DMC, *RMC, *GMC, *PMC, *LMC, and *EMC

Monitor commands not supported: DISP:MON:STAT and DISP:MON:CARD

Trigger commands not supported with MXIbus Extender Card as slot 0: OUTP:EXT:STAT ON | OFF, OUTP:ECLT:STAT ON | OFF, OUTP:STAT ON | OFF, TRIG:SOUR:EXT, and TRIG:SOUR:ECLT (Only EXT and ECLT parameters are not supported for this configuration. All other parameters are supported.)

In order to use the TRIG SMB connectors on the HP E1482B MXIbus Extender card, you must route the EXT trigger lines to the TTL trigger lines. This can be done by setting the MXIbus Trigger Configuration Register on the MXIbus Extender card. See the Compiled SCPI User’s Guide for a programming example.

COMMANDS CHANGED

The commands listed are different than in the Command Module version.

ABORT can abort a scan in progress when trigger source is immediate or external (when cscpi_overlap ON).

QUERY COMMAND RESPONSE TYPES

All but the following queries will return an integer.

SYST:ERR? int, quoted string

SYST:CTYP? string

SYST:CDES? quoted string

SYST:COPT? string

SYST:VERS? string

TRIG:SOUR? string

TRIG:SLOP? string

OPEN? string

CLOS? string

SCAN:MODE? string

SCAN:PORT? string

SETT:TIME? float

FUNC? string

*IDN? string

OVERLAPPING COMMANDS

The following commands continue execution by interrupt service routines after the command function returns to the user program (when cscpi_overlap ON):

*RST

*RCL

SYST:CPON

OPEN

CLOSE

INIT (unless scanning fets in a mixed (fet and non-fet) switchbox).

TRIG (unless scanning fets in a mixed (fet and non-fet) switchbox).

Commands may be sent to other instruments while the switch driver is finishing one of these commands.

The *OPC?, *WAI or *OPC commands may be used to read when the overlapping command has totally finished.

Commands which can run overlapped with overlapping commands:

If an overlapping command has been started and another command is sent to the same instrument, the second command will usually block, waiting for the previous command to finish, before executing. The following commands are the exceptions, they will run overlapped with an overlapping command:

*CLS

*OPC

ABORT (abort scan in progress)

If an overlapping command has been started and a query is sent to the same instrument, the query will usually run overlapped with the previous command.

The following are the exceptions, they will block, waiting for the previous command to finish prior to executing:

*OPC? (by definition)

*TST?

CLOS?

OPEN?

SETT:TIME?

ONSRQ RESTRICTIONS

In general, an srq function should not send commands to a switchbox while the main (foreground) program is sending commands to that instrument.

The following may NOT be used in an ON SRQ function which executes as an interrupt routine:

cscpi_overlap OFF (because the execution routines wait for an interrupt):

*RST

*RCL

*TST?

SYST:CPON

OPEN

CLOSE

INIT

TRIG

cscpi_overlap ON:

*TST?

INIT

If the SRQ function is called due to a scan complete from the same switchbox, then the commands which do not run overlapped with an overlapping command (documented above) can not be executed from the SRQ function.

If enabled, the following may cause an SRQ function to be executed from an interrupt routine:

cscpi_overlap ON:

Any overlapped command followed by *OPC

Trigger too fast error (during scan) Scan complete
If cscpi_overlap OFF, scan complete (if enabled) will cause an SRQ function to be executed only once at the end of the last scan, even if scanning channel list multiple times (arm count > 1).
