SYSTem:COMMunicate:LAN:CONTrol?
SYSTem:COMMunicate:TCPip:CONTrol?
Returns the initial socket control connection port number. This connection is used to send and receive
commands and queries. Unlike the data socket, which uses a fixed port number, the control socket
port number varies and must be obtained using these queries.
Parameter Typical Return
(none)
<port
#>
(0
if
sockets
not
supported)
Query the Control connection port: SYST:COMM:LAN:CONT? or SYST:COMM:TCP:CONT?
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 system clock is only used in conjunction with the BenchVue Power 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 system 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 clears the 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 30 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 <error code>,<error string>. The error string may contain up to
255 characters. For a list of error codes and message strings, see SCPI Error Messages.
