NF WF1973 - Sequence

7.10 Sequence
141
WF1973/WF1974
7.10 Sequence
Number of saved sequences 10 sequences (saved to non-volatile memory)
Maximum number of steps Maximum of 255 steps per sequence (not including step
of pre-start status)
Inter-channel operation In sequence mode, the mode of both channels is the
sequence mode. Step control is done in common for
both channels.
Step control parameters Step time, hold operation, jump destination, number of
jumps, step stop phase, branch operation, step
termination control, step sync code output
Intra-step channel parameters Waveform, frequency, phase, amplitude, DC offset,
square wave duty
In-step operations Constant, keep, linear interpolation (except waveform
switching)
Step time setting range 0.1 ms to 1,000 s (4 digits or 0.01 ms resolution)
Jump count setting range 1 to 999 or infinite
Step stop phase setting range 0.000° to 360.000° (CH1 reference phase. 0.001°
resolution) or invalid
Branch operation
State branch Check of state branch input from multi-I/O connector
at step end. Upon branch input detection, branching to
specified destination step
Event branch Immediate branching to specified destination step
through event branch manipulation or input
Control of step termination Sequence end or transition to next step
Step sync code output Output of 4-bit code specified for each step to multi-I/O
connector
LSB outputtable to sync/sub-output connector
Usable waveforms Sine wave, square wave, noise, DC, and arbitrary wave
Ramp wave and parameter-variable waveform can be
used through saving as arbitrary waveforms.
Maximum number of
usable waveforms 128
Step start phase Oscillation start from reference phase 0° of each
channel at next step after DC or noise (excluding DC
and noise)
Sequence manipulations Start, stop, hold/resume, event branch
Sequence external control
Input connector Use of 4 bits of multi-I/O connector
Control items Start or state branch, stop, hold/resume, event branch
Sequence external trigger input (start trigger)
Polarity Positive, negative, off (selectable)
Input connector Use of external trigger input on CH1 side. Input
voltage and input impedance follow the external
trigger input specifications.
