Indicates if there has been a change in the configuration since the last time the command was given, in the form
x, where:
0=No status change.
1=Status change has occurred.
NOTES:
1) A "status change" is defined as any time a parameter is changed, e.g., when a command is successfully
executed that changes a value. A status change also results when there is a fault condition.
2) A query does not set the status change flag. The status change flag is cleared after being read.
EXAMPLE: <0001/TSC?{CR}
>0001/TSC=0{CR}{LF}

numeric
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 mutes when an external reference oscillator is not
detected.
EXAMPLE: <0001/XRM=1{CR}
