TRAN- TRANSIENTS Screens
Transient sequences allow precise time-controlled changes to be made to voltage (AC and
DC mode) and frequency (AC mode only) under program control. A transient sequence
consists of one or more list entries (or segments) that are executed in sequence.
There are three types of Transients modes:
•
LIST Mode
•
STEP and RAMP Mode
•
PULSE Mode
Note that Step and Pulse transients can be
accomplished using LIST mode as well but
STEP and PULSE data entry is more
intuitive.
Transient lists are created or edited in EDIT mode and can be saved to non-volatile memory
as part of an instrument setup. They are executed in Execution mode.
The following sections cover all available transient modes.
6.6.1
LIST Mode
List mode is the most versatile transient data entry mode as it allows any of the other
Transients types to be created as well. However, entering a long ramp or step transient
consisting of many discrete steps in List mode is time consuming and tedious. It is also easier
to make a mistake in LIST mode than using the STEP or RAMP mode. Same is true for PULSE
transients which can be created with a short transient list as well.
LIST transients can be created from the front panel, using the LXI web server and a web
browser or with Pacific’s PPCS Manager Windows software.
An example Transient LIST created from the front panel is shown below.
