1
Remarks
 The *PSC 1 command means clearing the status byte enable register and standard event enable
register at power-on. The *PSC 0 command means the status byte enable register and standard event
enable register will not be affected at power-on.
 You can also send the *SRE
0 and *ESE 0 commands to clear the status byte enable register and
standard event enable register respectively.
Return Format
The query returns 0 or 1.
Example
*PSC 1 /*Enables clearing of the status byte enable register and standard event enable register at

Remarks
 The instrument provides 6 storage locations (No. 0 to 5) in the internal memory for storing the state
files. Sending this command can recall the state file stored in the specified storage location of the
internal non-volatile memory. Select the files from No. 0 to No. 5 to recall the state file stored in the
corresponding storage location respectively.
 This command is only valid when an effective state file is found in the specified storage location of the
internal non-volatile memory.
 The state file stored includes the dual-channel selected waveform, frequency, amplitude, offset, duty
cycle, symmetry, phase, modulation, sweep, burst parameters, frequency counter parameters, as well
as utility function parameters and system parameters under the Utility menu.
