Service Note 6652A-03
Situation:
The A2 GPIB board has changed from a hole through pc assembly to Surface Mount.
The new assembly 5060-3399 is a direct replacement for 5060-3317. When replacing
the older assembly, a ferrite core has been added to the cable between the A2 GPIB
board and the A1 Front Panel Board to insure the unit meets the radiated RFI specification.
Solution/Action:
Remove the top cover and replace the A2 pc assembly following the instructions in the
service manual.
Attach the ferrite core to the adhesive backed mount using the tie wrap. Remove the
protective backing and mount this assembly to the back of the front chassis adjacent to
the telephone style connector on the A1 front panel pc board. Remove and discard the
cable connecting two board. Install the new cable passing it through the center of the
ferrite core two times. If the unit already has one core, add the second core in parallel
with the first.
Replace the top cover and perform the Turn-On Checkout procedure in Chapter 3 of the
Operating manual. Connect the unit to a GPIB controller and insure the supply responds
to GPIB commands. Replacement of the GPIB board or the addition of the ferrite core
will not affect unit calibration.
