Synchronization of operations

While ramping its output, the Power Module uses, for the ramp calculations, a resolution
much higher than the output programming resolution. This fact ensures that no
calculation-induced errors will affect the produced output ramp.

Ramping must not be combined with any foldback mode other than mode
0 (voltage/current operating mode).

Output ramping setup

To produce a ramp, the XMP 2600 needs to know the start value, the ramp’s duration and
the desired end value. Using these values, the XMP 2600 calculates the data needed for
the Power Module to produce a precise up or down ramp.

When the parameters for the ramp operation are being programmed, the XMP 2600 needs
to know it should calculate the data needed by the Power Module to generate the ramp.
Therefore the ramp mode must be selected before the parameters for the ramp operation
are being programmed.

The following commands sequence example demonstrates the proper way to program the
XMP 2600 to produce a ramp. The example shown will setup Power Module No. 1 to
produce a voltage up-ramp. The same procedure can be used to produce a voltage down-
ramp or a current up or down ramp.

→

ramp end value

Note that the ARM command causes the Power Module to store the values programmed
by the VSET command that follow it. Thus, the output itself does not change until the
ramp operation is initiated.

Output ramping initiation

Once the ramp operation is setup the Power Module is waiting for a trigger in order to
start ramping its output.

The trigger can be supplied to the Power Module using one of the following methods:

Hardware trigger – TRIG input at the rear panel.

Global software trigger – using the TRIGER command.

Power Module trigger – using the command: TRIGER <ch>.

Synchronization of operations

The synchronization features of the XMP 2600 enable it to perform various simultaneous
or sequential operations with very tight timing.

Simultaneous

operations

The XMP 2600 provides synchronization mechanisms that enable you to command
simultaneous changes in the outputs of several Power Modules.
