Function Generator Commands
Note: Sequence data or table data, which you can write via SCPI commands, is not stored
in the unit.
The function generator is a complex part of the whole control options of the unit. It can be
remotely configured and controlled by a set of SCPI commands. When operating the
function generator on the front panel of the unit, it requires a certain setup procedure
before getting to the actual starting point. The single commands cannot enforce that
procedure, so it’s up to the user to use them in the correct sequence. What to do:
1.
You need to configure the function generator. One of the first things is to select the
type of function generator you want to use. Further steps depend on your selection.
There are two types available: XY and arbitrary. The XY function generator is usually
only used for the functions UI and IU, the arbitrary generator is used for the other
functions like sine wave, square wave etc.
2.
If you are going to use the arbitrary generator, there is another setup part to do
where you first select to which DC input/output value the function, voltage (U) or
current (I), will be applied to. The power (P) is not available for wave generation. As
a third part of the setup, you should set up the number of sequences to use. This
does not happen automatically when filling a certain number of sequences with
data, which is done later on.
If you are going to use the XY generator, there is another setup part to do where
you need to select whether it shall generate an U-I or I-U curve. Depending on that
setting, values you will write to the table, are interpreted. Without this selection,
the unit will not accept any table value.
3.
Now the sequence(s) to use are filled with data. The arbitrary generator can use X
out of 99 possible sequences, which are written with three commands each. The
number of sequences to use is variable, but at least 1.
The XY generator, on the other hand, should be filled with 4096 values, which are then
interpreted as either voltage, for UI function, or current for IU function, depending on the
selection in step 2.
After this, the function generator is completely configured and can be started
Note: When submitting curve data, it is loaded into an internal buffer, which takes some
time to process before the command is accepted. We recommend waiting at least 2
seconds after submitting the data and before the next command.
