SYSTem:DATE <yyyy>, <mm>, <dd>
SYSTem:DATE?
Sets the date of the system clock. Specify the year (2000 to 2099), month (1 to 12), and day (1 to 31).
The real time clock is only used in conjunction with the Keysight 14585A Control and Analysis
software.
Parameter Typical Return
<yyyy,<mm>,<dd> +2018,+04,+30
Set the date to June 30, 2018: SYST:DATE 2018,06,30
l The real-time clock does not adjust itself for time zone changes or daylight savings time.
SYSTem:ERRor?
Reads and clears one error from the error queue.
Parameter Typical Return
(none) <+0,"No error">
Reads and clear first error in error queue: SYST:ERR?
l The front-panel ERR annunciator turns on when one or more errors are currently stored in the
error queue. Error retrieval is first-in-first-out (FIFO), and errors are cleared as you read
them.When you have read all errors from the error queue, the ERR annunciator turns off.
l If more than 20 errors have occurred, the last error stored in the queue (the most recent error) is
replaced with -350,"Error queue overflow". No additional errors are stored until you remove errors
from the queue. If no errors have occurred when you read the error queue, the instrument
responds with +0,"No error".
l The error queue is cleared by the *CLS and when power is cycled. It is not cleared by a *RST.
l Errors have the following format (the error string may contain up to 255 characters).
<error code>,<error string>
For a list of error codes and message strings, see SCPI Error Messages.
SYSTem:LFRequency?
Returns the power-line reference frequency. This determines the integration time used by
SENSe:SWEep:NPLC command.
At power-on, if the line frequency mode is set to Auto, the power supply automatically detects the
power-line frequency (50 Hz or 60 Hz) and uses this value to determine the integration time used.
If the auto line detect fails because the line is noisy or out of tolerance, it uses a setting of 60 Hz.
