Bit no. Short description Bit is set if
7 Legacy locked state The power sensor is locked in the NRP legacy mode. Via the
SCPI channels (USBTMC or TCP/IP), only query commands
can be sent, but no setting commands.
When the first setting command is sent, the NRP legacy inter-
face takes precedence over all other command channels. This
bit is set to
1
, and all other channels can only execute query
commands. If a setting command is sent via a different chan-
nel, the power sensor indicates 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 power sensor.
8 Reference PLL locked state PLL for the clock reference is synchronized. The bit is useful
when selecting an external clock source.
The following states are possible:
●
Internal clock (
[SENSe<Sensor>:]ROSCillator:
SOURce INT
) :
–
1
(always)
●
External clock (
[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

Contains information on questionable sensor states that occur if the power sensor is
not operated in compliance with its specifications.
