KEPCO EL Series Electronic Load Operator Manual P/N 243-1295 Firmware Version 3.87 to 3.xx - Manual (Page 77)

SERIES EL 022013
B-15
Description: Indicates questionable events that occurred since previous STAT:QUES? query. Returns the
value of the Questionable Event register. The Questionable Event register is a read-only register
which holds (latches) all events. Reading the Questionable Event register clears it.
B.79 CONDition:QUEStionable:CONDition? QUERY
STAT:QUES:COND?
Syntax: Short Form: STAT:QUES:COND? Long Form: STATus:QUEStionable:CONDition?
Return Value: <NR1> =16 bits = actual Questionable condition register value
Description: Returns the value of the Questionable Condition Register. The Questionable Condition Register
contains unlatched real-time information about questionable conditions of the electronic load. Bit set to
1 = condition (active, true); bit reset to 0 = condition (inactive, false). (See example, PAR. B.75.)
B.80 STATus:QUEStionable:ENABle COMMAND
STAT:QUES:ENAB
Syntax: Short Form: STAT:QUES:ENAB <NR1> Long Form: STATus:QUESionable:ENABle <int_value>
Description: Programs Questionable Condition Enable Register. The Questionable Condition Enable Register
determines which conditions are allowed to set the Questionable Condition Register; it is a mask for
enabling
specific bits in the Questionable Event register that can cause the questionable summary bit
(bit 3) of the Status Byte register to be set. The questionable summary bit is the logical OR of all the
enabled bits in the Questionable Event register
. Bit set to 1 = function enabled (active, true); bit reset
to 0 = function disabled (inactive, false) .
B.81 STATus:QUEStionable:ENABle? QUERY
STAT:QUES:ENAB?
Syntax: Short Form: STAT:QUES:ENAB? Long Form: STATus:QUESionable:ENABle?
Return Value: <NR1> =16 bits = actual Questionable enable register value
Description: Reads Questionable Condition Enable Register. Electronic load returns value of Questionable
Condition Enable Register, indicating which conditions are being monitored. Bit set to 1 = function
enabled (active, true); bit reset to 0 = function disabled (inactive, false)
.
B.82 SYSTem:COMMunicate[:GPIB]:ADDRess COMMAND
SYST:COMM[:GPIB]:ADDR
Syntax: Short Form: SYST:COMM[:GPIB]:ADDR <NR1>
Long Form: SYSTem:COMMunicate[:GPIB]:ADDRess <NR1>
Where: <NR1> = numbers from 1 to 30 comprising the GPIB Address. Factory default GPIB address
is 10.
Description: Sets the GPIB Address to be used during communication over the GPIB interface. After setting
the address, the EL Load must be power cycled (turned off, then on) in order for the new GPIB
address to take effect. Command is not valid from the GPIB interface.
B.83 SYSTem:COMMunicate[:GPIB]:ADDRess? QUERY
SYST:COMM[:GPIB]:ADDR?
Syntax: Short Form: SYST:COMM[:GPIB]:ADDR?
Long Form: SYSTem:COMMunicate[:GPIB]:ADDRess?
Returns: <NR1> = number from 1 to 30 comprising the GPIB Address
Description: Returns the GPIB Address used during communication over the GPIB interface. Command is
not valid from the GPIB interface.
B.84 SYSTem:COMMunicate:ECHO COMMAND
SYST:COMM:ECHO
Syntax: Short Form: SYST:COMM:ECHO <bool> Long Form: SYSTem:COMMunicate:ECHO <bool>
Where: 1 or ON turns on echo, 0 or off turns off echo
Description: Causes the EL Load to return the parsed string to the user. The parsed string may not be the
complete string sent to the EL; the parsed string contains the short form mnemonic for the command.
Factory default is SYST:COMM:ECHO off.
