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 ofusable 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.
