Remarks The Register is not affected by signal generator preset or *RST. However, cycling the signal
generator power will reset this register to zero.
*IDN?
The Identification (IDN) query outputs an identifying string. The response will show the
following information: <company name>, <model number>, <serial number>, <firmware
revision>
*OPC
The Operation Complete (OPC) command sets bit 0 in the Standard Event Status Register when all
pending operations have finished.
The Operation Complete command causes the device to set the operation complete bit (bit 0) in the
Standard Event Status Register when all pending operations have been finished.
*OPC?
The Operation Complete (OPC) query returns the ASCII character 1 in the Standard Event Status
Register when all pending operations have finished.
This query stops any new commands from being processed until the current processing is complete.
This command blocks the communication until all operations are complete (i.e. the timeout setting
should be longer than the longest sweep).

The options (OPT) query returns a comma-separated list of all of the instrument options
currently installed on the signal generator.

Request Enable Register, the Standard Event Status Enable Register, and device- specific event enable
registers.
ON (1) This choice enables the power- on clearing of the listed registers.
OFF (0) This choice disables the clearing of the listed registers and they retain their status when
a power- on condition occurs.
*PSC?
The Power-On Status Clear (PSC) query returns the flag setting as enabled by the *PSC
command.
*RCL <reg>
The Recall (RCL) command recalls the state from the specified memory register <reg>.
*RST affected
The Reset (RST) command resets most signal generator functions to factory- defined conditions.
Remarks Each command shows the [*RST] default value if the setting is affected.
*SAV <reg>
The Save (SAV) command saves signal generator settings to the specified memory register
<reg>.
Remarks The save function does not save all signal generator settings. Refer to the User’s Guide
for more information on the save function.
