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:  *DMC, *GMC, *PMC, *LMC, *EMC, *RMC, MEM:DEL:MACR, and SYST:PIM
 
Monitor commands not supported:  DISP:MON:STAT and DISP:MON:CHAN
 
Learn command not supported:  *LRN
 

COMMANDS CHANGED

 
 
The commands listed are different than in the Command Module version.
 
The MEM:VME:ADDR parameter is a user pointer instead of an absolute VME address.  To store readings from INIT directly to a user array use float array[reading_count];
 
      INST_SEND(vm, "MEM:VME:ADDR %d", (long) array);
 
      INST_SEND(INIT);
 
To store readings in an external VME memory card, use the HP SICL function imap() to get the user address of the memory card and pass that address to INST_SEND.  The VME card must support D32 transfers.
 
 
READ? is the same as INIT; FETCH?   The information in the User’s manual about INIT, READ? and output buffers is not relevant to the Compiled SCPI implementation.  In Compiled SCPI, MEAS:...? and READ? are identical to INIT in requiring reading buffer storage.  If you get an out of memory error, have your system administrator increase the maximum data size allowed for user programs.

All other query commands return an integer.
 

CAL:VALUE?  double

OVERLAPPING COMMANDS

 
The following slow commands continue execution as interrupts after the command function returns to the user program:
 
SENS:FUNC
 
SENS:[VOLT | RES]:APER
 
SENS:[VOLT | RES]:NPLC
 
SENS:[VOLT | RES]:RES
 
CONF:....
 
INIT  (for aperture >= 2.5 ms)
 
*RCL
 
*RST
 
This feature may be used to set up other instruments while the HP E1326 is also finishing a command. The *OPC? or *OPC commands may be used to read when the overlapping command has totally finished.
 

ONSRQ RESTRICTIONS

 
The following commands can not be used in SRQ handlers which execute as an interrupt routine since they internally call iwaithandler:
 
if cscpi_overlap off
 
SENS:FUNC
 
SENS:[VOLT | RES]:APER
 
SENS:[VOLT | RES]:NPLC
 
SENS:[VOLT | RES]:RES
 
CONF:....
 
*RCL
 
*RST
 
INIT, READ?, MEAS?  (for aperture >= 2.5 ms) or with 1460 scanners
 
 
The following commands may cause an SRQ handler to execute from an interrupt routine if SRQ is enabled on the condition:
 
Any overlapped command followed by the *OPC command with cscpi_overlap on.
 
An INIT, READ? or MEAS? command with aperture >= 2.5 ms which sets the error bit from a timer too fast error.
