Response: <NR1>
The value of the Status Byte read with the *STB? query may differ from that read with the Serial Poll.
Bit 6 of the STB will be set as long as a reason for requesting service exists, while bit 6 of the STB as
read by the Serial Poll is cleared by the Serial Poll.
4.11.5 Device Trigger Commands
*TRG - Trigger command
This command is analogous to the IEEE 488.1 Group Execute Trigger interface message, and has the
same effect. It is used to trigger the device to output a wave, and is accepted only when the trigger
mode is set to Trigger, Gate or Burst, and the trigger source is set to BUS.
Command Type: Common Command
Syntax: *TRG
4.11.6 Stored Settings Commands
4.11.6.1 *RCL - Recall Instrument State
This command is used to restore the state of the device to that stored in the specified memory location.
COMMAND TYPE: Common Command
Syntax: *RCL<ws><NRf>
Arguments:
Type: <NRf>
Range: 0 to 99. Non integer values are rounded before execution
Example: *RCL 0 (Recall default state)
*RCL 99
4.11.6.2 *SAV - Save Instrument State
This command is used to store the current instrument state in the specified memory location.
COMMAND TYPE: Common Command
Syntax: *SAV<ws><NRf>
Arguments:
Type: <NRf>
Range: 1 to 98. Non integer values are rounded before execution
Example: *SAV 25
Stored setting location 0 stores the factory defaults, and is a read-only location. Location 99 stores a
copy of the current instrument setting, and it, too, is read-only.
4.12 Instrument Control Commands
Instrument control commands are grouped into logical subsystems according to the SCPI instrument
model. The commands are comprised of mnemonics indicating the subsystem to which the command
belongs, and the hierarchy within that subsystem. When the command is to be referred to the Root
node, it should be prefixed with a colon (:). Mnemonics appearing in square brackets [...] are optional.
The '|' character is used to denote a choice of specifications. The '<ws>' is used to denote a white space
character.
