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 For more (VXIbus) system configuration information, refer to the C-Size
VXIbus Systems “Installation and Getting Started Guide".
The Digitizer
Logical Address
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.)
Assigning the Digitizer
to a Commander
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.
