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

11.2.3 Questionable status register

Contains information on questionable sensor states that occur if the power sensor is

not operated in compliance with its specifications.
