11 STATus Subsystem
474 N1911A/1912A P-Series Power Meters Programming Guide
– STATus:DEVice:NTRansition is 1, then STATus:DEVice:EVENt? is set when a
power sensor is disconnected.
– STATus:DEVice:PTRansition is 1, then STATus:DEVice:EVENt? is set when a
power sensor is connected.
The Channel A and B sensor error bits (3 and 4) are set to:
– 1, if the P-Series, N8480 Series or E-Series power sensor EEPROM has failed
or if there are power sensors connected to both the rear and front panel
connectors.
– 0, for every other condition.
The Front Panel key press bit (bit 14), when queried with the STATus:DEVice:EVENt?
query indicates whether any front panel keys have been pressed since power up or since
you last queried the device status register. This bit ignores the :NTRansition, and
:PTRansition registers and a :CONDition? query always returns a 0.
Querying STATus:DEVice:EVENt? clears the STATus:DEVice:EVENt? register.
