4.2.10.2 Unlock Remote I/O Session (Remote Command only)
You can unlock the SCPI control of the current I/O Interface and Session by sending
:SYSTem:LOCK:RELease. Lock requests on an individual interface and session can
be nested, and each request increases an internal lock count by 1. For every granted
request, you will need to perform a release. The lock is not relinquished until the
internal lock count reaches 0.
Remote
Command
:SYSTem:LOCK:RELease
Example
:SYST:LOCK:REL
Notes When the instrument is unlocked, Bit 0 is cleared in the Operation Instrument status register
