Sum of SERR bits
The sum/combination of SERR bits 1 to 4.
1
SERR measurement not possible
Static error (SERR) exists; certain parameter settings could lead to a situation where subse-
quent measurements are not possible (for example, a Timeslot measurement with a config-
ured timeslot width of 0.0)
2
SERR erroneous results
Static error exists; the measurement result is possibly incorrect.
3
SERR warning
A static error exists therefore the Status LED of the power sensor is blinking slowly in red.
4
SERR critical
A critical static error exists therefore the Status LED of the power sensor is blinking fast in
red.
5 to 6

7
Legacy locked state
The power sensor is locked in the NRP Legacy mode. Via the SCPI channels (USBTMC or
TCP/IP) only the usage of query commands is possible, and no setting commands.
The NRP legacy interface takes precedence over all other command channels when the
first setting command is sent via this interface. Then this bit is set to
1
and all other chan-
nels can then only execute query commands. If a setting command is sent via a different
channel, the sensor raises an error:
-200,"Execution error; sensor in LEGACY mode"
To leave this operating mode, close the NRP legacy channel. Either close the application
which opened the NRP legacy channel or close at least the connection to the sensor.
8
Reference PLL locked state
This bit signals whether the PLL for the clock reference is synchronized. The bit is useful
when selecting an external clock source.
The following states are possible:
●
[SENSe<Sensor>:]ROSCillator:SOURce
INT
) :
–
1
(always)
●
[SENSe<Sensor>:]ROSCillator:SOURce
EXT
) :
–
1
if the sensor was able to synchronize with external clock
–
0
if the sensor could not synchronize with external clock
