DSA8200 Digital Serial Analyzer and Modules Service Manual
Exchanging the Electrical Sampling Module
If it is determined that a sampling module failure is caused by an internal part,
you must exchange the complete sampling module chassis to Tektronix. The
customer will keep the cover and attaching hardware (except for the 80E07,
80E08, 80E09, and 80E10). Sampling module exchange can be made with either
your local Tektronix service center or central Tektronix exchange in Beaverton,
Oregon.
NOTE
. The 80E07, 80E08, 80E09, and 80E10 Electrical Remote Sampling
modules should not be disassembled. Return the entire module assembly.
1.
Transport the chassis sampling modules with terminations on the inputs.
2. Transport the chassis sampling modules in their original containers and store
the sampling modules on a metal or conductive surface.
3. When handling the exposed chassis sampling module only, do not touch any
exposed component on the circuit board. Grasp the exposed module by the
edges of the circuit board or the rear or front housings.
Program the serial number (printed on the sampling module cover) into the new
replacement sampling module chassis.
1. Reinstall the chassis into the cover following the procedure on page 4--75.
2.
Install the electrical sampling module into one of the instrument’s slots.
3. Connect a GPIB cable to the GPIB port of the instrument connect the
remaining end to the GPIB port of a PC.
CAUTION. Do not have any user interface dialogs active. Dialogs such as
Compensation, System properties will prevent the instrument from responding to
GPIB commands.
4. Enter the following GPIB commands:
a. SYSTem:PROTect OFF
b. SYSTem:PROPerties:CH(1-8):SERialnum <serialNum_string>
Example: SYST:PROP:CH3:SER “B010123”
