HP E1340A AFG Status
The Operation Status Group monitors current operating conditions within
the AFG. The specific conditions include:
execution of the
Calibration, sweeping, and the

Bit 0 is set (1) during the execution of the

Bit 3 is set (1) while a frequency sweep is in progress. The bit

is cleared (0) when waveform generation is halted and frequency sweeping
is not selected.
Bit 8 is set (1) when the

is set; otherwise waveform generation begins when the AFG
receives the first start arm. The bit is cleared (0) when waveform generation
is complete after the waveform is aborted (by an
command, or a Device Clear). The AFG then returns to the Idle state.
Reading the Condition Register
Bit settings in the Condition Register can be determined with the command:
STATus:OPERation:CONDition?
Bits 0, 3, and 8 have corresponding decimal values of 1, 8, and 256.
Reading the Condition Register does not affect the bit settings. The bits are
cleared following a reset (
The Transition Filter specifies which type of bit transition in the Condition
Register will set corresponding bits in the Event Register. Transition Filter
bits may be set for positive transitions (0 to 1), or negative transitions (1 to
0). The commands used to set the transitions are:
