Configuring User-Defined Arbs
78
User-defined Arbs can contain up to 511 voltage or current steps that
are entered individually in the User-defined Properties window.
You can also populate the User-defined voltage or current Arb with
values from a previously configured "standard" arbitrary waveform
and then edit the steps in the User-defined Properties window.
To convert one of the standard Arbs, program the standard Arb
parameters and then select the Edit Points button to populate the
User-defined Arb with the values from the standard Arb.
You can also import a User-defined Arb that was previously created
using a spreadsheet as explained later in this chapter under
"Importing and Exporting User-Defined and Constant-Dwell Arb
Data".
Step 1 – Select a voltage or current User-defined Arb:
Press the Arb key twice or press the Arb key and then Properties to
access the Arb Selection window.
In the Arb Type dropdown menu, select either a Voltage or Current
Arb type. Then select the Pulse output type.
Step 2 – Configure the User-defined properties:
To configure the parameters of the User-defined waveform, press the
Properties key or select the Arb Properties button.
For step 0, enter the voltage or current values. Then enter the time or
dwell for the step. Check the Trigger box if you wish to generate an
external trigger signal at the start of the step.
Select the Add button to insert a new step below the selected step.
Note that the values in the new step are copied from the previous
step. Edit the values in the step. Select Clear if you want to clear all
values. Select Delete if you want to delete the selected step. Continue
to Add steps until your waveform is complete. Use the ▲ ▼
navigation keys to move through the list.
Specify what happens when the waveform completes – select
whether the output returns to the DC value that was in effect before
the waveform started, or whether the output should remain at the
last Arb value.
