STATus Subsystem

Device Status Register Sets

Agilent 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 Agilent 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
