Caution The 800 Vpk level is a product safety test specification and does not assure correct product operation if 800 Vpk transients have been applied. To maintain product functionality and performance, do not exceed ±42 Vpk on the single-ended inputs, or ±102.4 Vpk on the differential inputs.

Preparation for Use

This section contains configuration information specific to the

HP E1429A/B digitizer.

Note

The Digitizer Logical Address

Assigning the Digitizer to a Commander

For more (VXIbus) system configuration information, refer to the C-Size VXIbus Systems “Installation and Getting Started Guide".

The HP E1429A/B digitizer logical address is used:

to place the digitizer in the servant area of a commander

(e.g. HP E1406 Command Module, embedded controller, or another instrument).

to address the digitizer (see “ Addressing the Digitizer” or “ Using an Embedded Controller” later in this chapter.)

In a VXIbus system, every device must be in the servant area of a commander (with the exception of the top-level comander).

Note the following when assigning the digitizer to a commander:

A commander’s servant area is defined as:

Servant area = (logical address + 1) through (logical address + servant area switch setting)

The HP E1429A/B digitizer is a message-based device. If an embedded controller and an HP E1406 Command Module are part of your VXIbus system, put the digitizer in the servant area of the controller. This enables you to program the digitizer at higher speeds across the VXIbus backplane, rather than over the Hewlett-Packard Interface Bus (HP-IB*) via the Command Module.

* HP-IB is Hewlett-Packard’s implementation of IEEE Std. 488.1-1978
