80A05 Electrical Clock Recovery Module User Manual
This chapter familiarizes you with the operation of your module. This chapter
describes the front-panel controls and connectors, interaction of the module with
your instrument, user adjustments, and the programmer interface.
Figures 2 and 3 on page 8, show the front panel of the module and identifies the
connectors and indicators.
CAUTION. To prevent damage to your module or instrument, do not apply a
signal outside the Maximum Input Voltage Swing for your module.
To prevent electrostatic damage to the instrument and modules, follow the
precautions described in this manual and the manuals accompanying your
instrument. (See Electrostatic Discharge starting on page 5.)
Always use a wrist strap (provided with your instrument) when handling
modules or making signal connections.
The input circuitry in your module is very susceptible to damage from overdrive
signals and electrostatic discharge. Never apply a DC or peak voltage greater
than the Maximum Operating Range (see Table 4 on page 11) of your module.
Only operate the instrument and module in a static-controlled environment.
The 80A05 module contains three primary features:
Use these to secure the module in the instrument module compartment once
connected. Turn clockwise to secure and counterclockwise to release. To prevent
damage to the module, use the compartment ejectors to remove the module from
the compartment (see Figure 1 on page 4 for the location of the ejectors).
There is one LED on the front panel of the 80A05 module that indicates the
clock recovery circuitry is on and programmed to the requested bit rate. The
80A05 module receives power through the TEKPROBE-Sampling interface.
When the module is receiving power the LED is lighted. If the module is
installed but is not receiving power, check that the module is seated correctly.
