- class Constants
Bases:
object- GRID_TIME = 4
Clock period of the sequencers. All time intervals used must be multiples of this value.
- LOOP_UNROLL_THRESHOLD = 4
Size above which loops have tolerable overhead
-
MAX_012_BINNED_ACQUISITIONS:
int= 131072
-
MAX_345_BINNED_ACQUISITIONS:
int= 65536 Each sequencer has 131072 bins with some caveats. If you are using all sequencers you are limited to 131k bins for the first three sequencers and 65536 bins for the final three to a maximum number of 589824 bins.
- MAX_GAIN = 32767
Maximum gain in Q1ASM programs.
- MAX_GAIN_SIZE = 65535
Max size of gain in Q1ASM programs.
- MAX_OFFSET = 32767
Maximum offset in Q1ASM programs.
- MAX_OFFSET_SIZE = 65535
Max size of offset in Q1ASM programs.
- 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.
-
MAX_TOTAL_BINNED_ACQUISITIONS:
int= 589824
- 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.
- MIN_GAIN = -32768
Minimum gain in Q1ASM programs.

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_MAX_FREQ = 500000000.0
Maximum NCO frequency

Number of sequencers supported by a QRM/QRM-RF in the latest firmware.
- REGISTER_SIZE = 4294967295
Size of registers in Q1ASM programs.
