STATus Subsystem
Device Status Register Sets
HP E4418B/E4419B Programming Guide 10-9
The Channel A and B sensor connected bits (bits 1 and 2), when queried
with the STATus:DEVice:CONDition? query are set to:
• 1, when a power sensor is connected.
• 0, when no power sensor is connected.
The Channel A and B sensor connected bits (bits 1 and 2), when queried
with the STATus:DEVice:EVENt? query indicate whether a power sensor
has been connected or disconnected depending on the state of the
corresponding bits of STATus:DEVice:NTRansition and
STATus:DEVice:PTRansition. If the corresponding bit in:
• STATus:DEVice:NTRansition is 1, then
STATus:DEVice:EVENt? is set when a power sensor is
disconnected. Note, querying STATus:DEVice:EVENt? clears the
STATus:DEVice:EVENt?register.
• STATus:DEVice:PTRansition is 1, then
STATus:DEVice:EVENt? is set when a power sensor is connected.
Note, querying STATus:DEVice:EVENt? clears the
STATus:DEVice:EVENt?register.
The Channel A and B sensor error bits (3 and 4) are set to:
• 1, if the HP 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 Channel A and B sensor Front/Rear bits (bits 5 and 6) are set to:
• 1, if the power sensor is connected to the rear panel.
• 0, if the power sensor is connected to the front panel.
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. Note, this bit ignores the :NTRansition, and
:PTRansition registers,and a:CONDition?query always returns a
0.
