The active load and driver operate into a 50 Ω termination.
Figure 74 and Figure 75 illustrate how the various IO resources
(driver, comparator, and so on) are related to keywords which are used
in the equation sets to assign level values to the resources.
Clamping (C- and P-Channel Boards vs. Ce-
Channel Board)
For the Agilent 93000 SOC Series two different standard channel
boards exist. These different channel boards are used in the models
P330, P600, P800 and P1000 (C- and P- channel boards) and in the
models C200e and C400e (Ce- channel boards).
Clamping One difference between the channel boards is the clamping. Clamping
is used to smooth the output signal of the device. Peaks generated by
reflections of the signal can be limited by specific voltage levels (vch =
voltage clamp high; vcl = voltage clamp low).
The clamp voltages are programmable in the range of -2V to +6V.
