Specifications

Nominal Traits

The HFS 9000 family of high-speed logic signal source instruments have a
modular architecture with factory-configurable cards. The channels are digitally
synthesized from a common clock resulting in highly accurate independent
placement of rising and falling edges. The instruments are optimized for digital
device characterization with unique triggering capabilities and a variety of pulse
outputs. The product family also features low RMS jitter, the ability to compen­sate for external cable skews, and an easy-to-use graphical human interface.

This section contains the complete specifications for the HFS 9000 Stimulus
System and Modules. These specifications are classified as either nominal traits,
warranted characteristics, or typical characteristics.

Nominal traits are described using simple statements of fact such as “+2.6 V” for
the trait “Maximum high level,” rather than in terms of limits that are perfor­mance requirements.

Minimum low level –2.00 V
Maximum amplitude 3.00 V
Minimum amplitude 0.50 V
Level resolution 0.01 V

through 50  to –2 V

Description

Output levels will be approximately 1 V more negative than
the values programmed, specified, and displayed. Actual
output levels more negative than –2 V may cause
malfunction. Level accuracy specifications do not apply
when terminating to –2 V. Both true and complement
outputs must be terminated to the same voltage.
