SCPI 3.4 Status commands (Specification according to „1999 SCPI Command reference“:19 StatusSubsystem) The Operation Status Register (OPER) (see diagram on previous page) stores the several status (remote, local etc. ) in register Condition and forwards them to the register Event, as long as they are enabled by Enable. The masks Positive transition and Negative transition determine if the events are triggered by a rising edge or a falling edge.

SCPI The lock state can be queried by this command: SYSTem: LOCK :OWNer? -><B1> Get the current lock state NONE: if returned, the device can be put to remote mode (Bits 8,9,10 =0 in OPER:Condition) LOCal: device is in local mode and blocked for remote mode (Bits 8=1,9=0,10=0 in OPER:Condition ) External mode is interpreted as LOCal.

SCPI Attention! The following command is only supported by the Ethernet card IF-E1B! SYSTem: COMMunicate: NETwork :MAC? -><SRD> Query the MAC address of the Ethernet card :IPADdress? -><SRD> Query the actual IP address of the unit, which will be returned in the typical format.
SCPI 3.6 Commands to control the input Activate/deactivate the power input. INPut[:STATe]? ->B0 Queries the state of the electronic load input INPut[:STATe] <B0> Switches the electronic load input on/off Examples: INPON Switches the power input on, but does not reset alarms or warnings. It means, if an alarm is persistent the command can‘t be executed.

SCPI V. Set values for pulse width and rise time (Level A/B operation) (Specification according „1999 SCPI Command reference“:19 Source Subsystem) • Supported since device firmware 3.01 and up. The set values for the pulse widths of A (HIGH) and B (LOW), as well as the rise time can be queried anytime. Also see items I.
SCPI 3.9 Special commands Example 2: The actual values of voltage, current and power shall be 3.9.1 SYST:DATA:SET and SYST:DATA:REQ queried from the device. This is done by a REQuest. Accor- ding to the object lists, the object 71 returns all three actual Note values at once in form of six single bytes.
SCPI 4. Errors Errors are collected in an error queue. The bit indicates, if a new error has occured. It can be queried with a status re- gister byte call (STB?). The error queue is queried seperately and is automatically cleared when read. <ERR>...
