- class Constants
Bases:
object- GRID_TIME = 4
Clock period of the sequencers. All time intervals used must be multiples of this value.
- IMMEDIATE_MAX_WAIT_TIME = 65532
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.
- LOOP_UNROLL_THRESHOLD = 4
Size above which loops have tolerable overhead
- MAX_QCM_OFFSET_V = 2.5
Maximum offset for QCM
- MAX_QCM_RF_OFFSET_MV = 73
Maximum offset for QCM-RF
- MAX_QRM_OFFSET_V = 0.09
Maximum offset for QRM
- MAX_QRM_RF_OFFSET_V = 0.09
Maximum offset for QRM-RF
-
MAX_SAMPLE_SIZE_SCOPE_ACQUISITIONS:
int= 16384 Maximal amount of scope trace acquisition datapoints returned.
-
MAX_SAMPLE_SIZE_WAVEFORMS:
int= 16384 Maximal amount of samples in the waveforms to be uploaded to a sequencer.
- MIN_QCM_OFFSET_V = -2.5
Minimum offset for QCM
- MIN_QCM_RF_OFFSET_MV = -84
Minimum offset for QCM-RF
- MIN_QRM_OFFSET_V = -0.09
Minimum offset for QRM
- MIN_QRM_RF_OFFSET_V = -0.09
Minimum offset for QRM-RF
- NCO_FREQ_LIMIT_STEPS = 2000000000.0
The maximum and minimum frequency expressed in steps for the NCO set_freq instruction. For the minimum we multiply by -1.
- NCO_FREQ_STEPS_PER_HZ = 4.0
The number of steps per Hz for the NCO set_freq instruction.
- NCO_PHASE_STEPS_PER_DEG = 2777777.777777778
The number of steps per degree for NCO phase instructions arguments.
-
NUMBER_OF_REGISTERS:
int= 64 Number of registers available in the Qblox sequencers.
- NUMBER_OF_SEQUENCERS_QCM = 6
Number of sequencers supported by a QCM/QCM-RF in the latest firmware.
- NUMBER_OF_SEQUENCERS_QRM = 6
Number of sequencers supported by a QRM/QRM-RF in the latest firmware.
- REGISTER_SIZE = 4294967295
Size of registers in Q1ASM programs.
