Enhanced Frontend Support; External Clock Multiplier - HP 81200 User Manual

What's New in This Release? Major Changes from Rev. 2.0 to 2.1

Enhanced Frontend Support

The E4838A and E4837A frontends provide new capabilities. These
capabilities are supported by the Parameter Editor for ports, terminals,
and channels using these frontends.
New E4838A Setup Parameters
The additional setup parameters for the E4838A generator frontend
include:
• Rise/fall time
• Signal termination
• Analog channel addition
New E4837A Setup Parameters
The additional setup parameters for the E4837A analyzer frontend include:
• Data interpretation
• Signal termination
• Signal voltage range

External Clock Multiplier

There are applications where parts of the DUT are running at different
frequencies (for example serial-to-parallel converters, parallel-to-serial
converters, multiplexers, and so on).
Such applications require a system with two central clock modules (two
clockgroups), one running as a slave to the other. However, if the different
frequencies were not binary rated (such as 1:7, 1:10, etc), one had to spend
an additional data channel for generating the second frequency.
On from revision 2.1, the external clock multiplier is available. That means,
the clock applied to the EXTERNAL input of the central clock module can
be multiplied by any factor between 1 and 256.
The only restriction is that the external clock frequency must be higher
than 1.3 MHz (330 MHz divided by 256).
