2.10 Memory Sequence
In the memory-sequence operating mode the instrument automatically services a list with stored
instrument settings. Memory locations 1 to 50, which are loaded using SAVE and whose stored settings
are called either separately using RECALL or automatically and subsequently in the SEQUENCE mode,
are available.
The list is continuously serviced from the beginning to the end with a continual index. The order of the
memories to be passed through is arbitrary. Each setting can be assigned a freely selectable dwell time.
The dwell time determines the duration of the setting, its minimal value is 50 ms, its maximal value 60
sec.
The list is divided up into 3 columns for list index, memory location number (Memory) and dwell time
(Dwell) .. The beginning of the list has index 1.
Table 2-7 MEMORY SEQUENCE; Example of a list
Index Memory Dwell
001 09 50.0 ms
002 02 50.0 ms
003 01 75.0 ms
004 10 75.0 ms
... ... ...
Up to 10 sequence lists can be created. The total number of possible list elements is maximally 256.
I.e., a list can have 256 entries at the most, or less if several lists have been created.
Each list is identified by a separate name and selected via this name. A detailed description how to
process the lists can be found in Section 2.2.4, List Editor.
Note: Frequently changing the level in the operating mode MEMORY SEQUENCE can stress the
mechanically switched attenuator. The attenuator is also actuated when AM is switched on or
off. For this reason we recommend that you make use of the non-interrupting level setting as
much as possible and that you use the setting AM 0% instead of switching AM off.
Operating Modes (MODE)
The following operating modes are available:
AUTO
Run from the beginning to the end of the list with automatic restart at the
beginning. If another mode was activated prior to the AUTO operating mode,
continuation is made from the current index.
IEC-bus short command: :SYST:MODE MSEQ;
:SYST:MSEQ:MODE AUTO
:TRIG:MSEQ:SOUR AUTO
