Recommendations on using the XMP 2600

Usage Guidelines

Identify the XMP 2600

Using the *IDN? query, it is possible to verify that the device you are communicating with is indeed a XMP 2600 power system.

The *IDN? query also returns the firmware revision code for the XMP’s main controller. Use the GPIB? query to make sure the XMP 2600 is operating in IEEE488.2 mode.

Enforce power-on conditions

Power-on retain

Using the XMP 2600 in a computer controlled environment eliminates the need to use the Power On Retain feature because the controlling computer can easily re-program the XMP 2600 to a required state.

Therefore, set the Power On Retain feature to OFF (or NO). This can be done manually (using the front panel, in setup mode) or using the POR command. The XMP 2600 will remember your selection when it is turned off.

Clear / Retain Event Enable Registers

Similar to the Power On Retain issue, it is better to let the XMP 2600 clear the Event Enable Registers at power-on.

Clearing the Event Enable Registers is the default behavior of the XMP 2600 at power- on. Using the *PSC command, the XMP 2600 can be instructed to the behavior suitable for the user.

Use a CLR or RESET command

Use either the CLR (clear) or the RESET command to force the XMP 2600 to its initial conditions.

The RESET command will set the XMP 2600 to the exact state it would be in following turn-on.

The CLR command is similar to the RESET command with the following differences:

It will take the minimum number of actions necessary to set the XMP 2600 to its turn-on state. In contrast to the RESET command, Power Modules will not be reset if not necessary for clearing malfunctions.

The XMP 2600 main status structure is not cleared.

Following a CLR or RESET command you should wait for 15 seconds before attempting to communicate with the XMP 2600.

Setup the XMP 2600 status system

Before dealing with the Power Modules and to complete the XMP 2600 power system initialization, you should setup the mask registers of the XMP’s main controller status structure.

Use commands like *ESE, *PRE, *SRE and PEE to setup the XMP’s event and SRQ generation masks.

Query installed Power Modules

Before using the XMP 2600 power system, it is a good practice to make sure that the system contains the Power Modules that you expect it to have.
