Description of Arguments
(Note that all arguments are printable ASCII characters)
Query only.
Indicates if there has been a change in the configuration since the last time a command was issued, in the form
x, where:
0 = no status change
1 = there has been a status change.
A status change is defined as any time a parameter is changed, such as when command that changes a value is
successfully executed. A status change also results when there is a redundant switchover, or a fault condition.
A query does not set the status change flag. The status change flag is cleared after being read.
Example: <1/TSC?'cr'
>0001/TSC=0'cr''lf'
Command or Query.
Sets or returns the external reference mute state in the form x, where:
0 = Disable
1 = Enable (see Note)
Note: To enable this command, the internal reference oscillator option must be installed; otherwise, a mode
error will result. A hardware mute condition generated by the XRM mute is one of the conditions that can cause
the MUT command to return MUT=2.
When enabled, the unit will mute if an external reference oscillator is not detected.
Example: <1/XRM=1'cr'
