Creating a Test Sequence
Creating a Test Sequence
The IQS-3150 allows you to create test sequences so that the attenuation or
output power steps are performed automatically without your intervention.
The sequences can be saved and retrieved to be used as is or to be used as
a template in which you can insert or remove steps. To build a new
sequence starting with an old one, under Sequence File, click the Open
button.
To create a completely new sequence, under Sequence File, click the New
button.
A duration can be applied to each step individually, the duration value must
be between 0:00:00 and 999:59:59.
3. You can also set the time at which the sequence will start using one of
the following starting time modes:
³
Absolute: allows you to select a precise time (for example, 10:30:30
am) at which the sequence starts.
³
Relative: allows you to select a countdown between the moment you
start the sequence and the moment it actually starts.
In both modes, you cannot enter a value greater than 23:59:59.
You can also have the sequence repeated for a fixed number of times
(between 1 and 99999) or continuously.
Sequences can be created for both Attenuation and Output Power
(self-adjusting modules) modes.
