Module Contents

IMMEDIATE_SZ_GAIN[source]: Size of gain instruction immediates in Q1ASM programs.

IMMEDIATE_MAX_WAIT_TIME[source]: Max size of wait instruction immediates in Q1ASM programs. Max value allowed by assembler is 2**16-1, but this is the largest that is a multiple of 4 ns.

IMMEDIATE_SZ_OFFSET[source]: Size of offset instruction immediates in Q1ASM programs.

REGISTER_SIZE[source]: Size of registers in Q1ASM programs.

NCO_PHASE_DEG_STEP_COARSE = 0.9[source]: The phase (in deg) corresponding to an increase of 1 in the course argument of the q1asm instructions related to the NCO phases.

NCO_PHASE_NUM_STEP_COARSE = 400[source]: The maximum value of the course argument of the nco phase instructions.

NCO_PHASE_DEG_STEP_FINE = 0.00225[source]: The phase (in deg) corresponding to an increase of 1 in the fine argument of the q1asm instructions related to the NCO phases.

NCO_PHASE_NUM_STEP_FINE = 400[source]: The maximum value of the fine argument of the nco phase instructions.

NCO_PHASE_DEG_STEP_U_FINE = 3.6e-07[source]: The phase (in deg) corresponding to an increase of 1 in the ultra-fine argument of the q1asm instructions related to the NCO phases.

NCO_PHASE_NUM_STEP_U_FINE = 6250[source]: The maximum value of the ultra-fine argument of the nco phase instructions.

GRID_TIME = 4[source]: Clock period of the sequencers. All time intervals used must be multiples of this value.

MIN_TIME_BETWEEN_ACQUISITIONS = 1000[source]: Minimum time between two acquisitions to prevent FIFO errors.

SAMPLING_RATE = 1000000000[source]: Sampling rate of the Qblox control/readout instruments.

PULSE_STITCHING_DURATION = 1e-06[source]: Duration of the individual pulses when pulse stitching is used.
