Type

Bit Description

7:4

MEASUREMENT_

SEQUENCER_MOD1_

RESIDUAL_ENABLE_

PATTERN

0xF

R/W

Defines if a residual measurement on modulator 1 shall

be executed. The bit pattern does not represent a value

but controls bitwise which sequencer step shall be used.

The leftmost position of “0000” refers to sequencer step

3, the rightmost refers to sequencer step 0. By default a

residual measurement is done in all sequencer steps.

SEQUENCER_

WAIT_PATTERN

0x1

R/W

Defines if a sequencer step will wait for the modulator trigger

timer to finish as programmed in MOD_TRIGGER_TIMING and

WTIME. At the same time the timer is restarted. In case this bit

is not set, the next sequencer step will start as soon as all

measurements in the prior step are completed.

Please observe that MOD_TRIGGER_TIMING is “0” by default.

In this case the programmed wait pattern is ignored since

measurement time has always priority over wait time.

The bit pattern does not represent a value but controls

bitwise which sequencer step shall be used. The leftmost

position of “0000” refers to sequencer step 3, the rightmost

refers to sequencer step 0. By default the wait is executed for

sequencer step 0 (last sequencer step).
