REPETITION, REPETITION? – Number of Repetitions for Sequence
Function
Menu
Function
The REPETITION parameter determines how many times a
sequence will be repeated, which is defined by the current START
and STOP addresses.
i is an optional parameter which addresses the setup memory
(1 to 12/15) to which the repetition value will be written, and from
which it will be read.
Setting Command
Syntax:
REPETITION n(,i)
Value range:
0
n
255
Default setting
or after RESET (*RST):
0
Query Command
Syntax:
REPETITION? (i)
Sample response string:
REPETITION n
Parameters List
RLOAD? – Load Resistance
Menü
Function
The RLOAD function supplies the value of the current load resis-
tance as a quotient of output voltage and output current.
Query Command
Syntax:
RLOAD?
Sample response string:
RLOAD +XXX.XXX
Measuring range: As the UOUT and IOUT measuring functions
are used, the corresponding measuring range limits apply.
If the output is inactive (OUTPUT OFF) or one (or both) measuring
quantities UOUT and/or IOUT exceed or fall short of the measur-
ing range limits or if the mathematical value cannot be displayed
in the numerical format „XXX.XXX“, RLOAD = UOUT / IOUT is
shown for the quotient in the „OL“ display and „999999.“ is
entered in the data string.
SEQUENCE, SEQUENCE? – Automatic Sequential Recall of Stored
Setting Values, Sequence Status Query
Menu
Function
The sequence function makes it possible to generate voltage and
current profiles over a period of time, for example in order to
create test signals.
The required setting values and parameters are saved to the
appropriate memory to this end.
Values are saved with the commands
SM_STORE ADR
or
STORE ADR,USET,ISET,TSET,FSET.
1536/1700 memory
locations are available for this function. If dwell time is set to
TSET = 0, an overriding TDEF becomes effective.
The following control commands determine the course of the
sequence. The sequence is defined by means of START and
STOP addresses (
START_STOP xxxx,xxxx
), and the number
of repetitions (
REPETITION n
).
Note
: With appropriate configuration, sequence control (GO/STOP
or START/STEP) is also possible via the trigger inputs (analog
interface).
The SEQUENCE function cannot be combined with the PSET
function!
Setting Command (sequence control command)
Syntax:
SEQUENCE txt
Control Parameters List
If an addressed memory location is empty (no executable
content), the sequence jumps to the next higher executable mem-
ory location.
1
Step-by-step control (remote / manual)
If the
T_MODE
parameter is set to “RCL”
, the step
pulse can be specified by means of an external
signal applied to the appropriate trigger input at the ana-
log interface.
2
A memory address can be specified as an
additional, optional parameter for these commands,
as of which sequence execution is started or resumed.
Example:
SEQUENCE CONT,n
where start address
n
stop address

Param-
eter
Content Meaning
txt
OFF
Jump to stop address and end the sequence run or step-by-step
control; same as stop.
If there is no content (CLR), the power output is switched (OUTPUT
OFF).
GO
Start sequence run as of start address
HOLD
Pause, suspend sequence at current memory location
CONT
2
Resume automatic sequence run with next executable memory
location
STRT
1
Jump to start address and execute its content.
Power output is switched on, step-by-step control is possible.
STEP
1, 2
Execute the next valid memory location.
In the case of step-by-step control, the “repetition” parameter is
ignored, i.e. a subsequence, for example, is executed only once.
BSTP
1
The “repetition” parameter is ignored, subsequences are skipped,
ramp functions are executed just like “NF”
STOP
1
Jump to stop address and end the sequence run or step-by-step
control.
If there is no content (CLR), the power output is switched (OUTPUT
OFF).
ESC
Sequence is ended using the momentary setting without jumping to
the final value.
