Connector replacement
The DATA IN and DATA OUT connectors use Planar Crown® adapters. These facilitate user replacement of the adapter,
should it become damaged. Replacement adapters can be ordered from Tektronix.
Replace the front panel connectors
The adapter is secured to the connector with a captive threaded mounting ring.
1. Remove a damaged connector by grasping the knurled outer portion of the ring with your fi ngers and turning
counter-clockwise.
Do not allow foreign material to enter the connector body when replacing the adapter.
2. Position the two locating tabs in the corresponding slots of the instrument-mounted portion of the connector and seat
the replacement adapter.
3. Align the retaining ring and tighten by rotating clockwise.
Tightened the connector fi nger-tight. To avoid over-tightening and possibly damaging the connector, do not use a tool
to tighten it.
Fuse replacement
The instrument is protected by a fuse placed in series with the power line input. The fuse is conservatively rated and should
never open through the life of the instrument. A blown fuse would generally indicate a problem with the instrument which
requires factory service. It is recommended that you arrange to have the instrument serviced if you experience a blown fuse.
Instrument calibration
The instrument uses digital calibration of the output buffers. To maintain the accuracy of the output amplitude and offset,
annual calibration is recommended. Contact Tektronix to schedule instrument calibration.
Repack the instrument for shipment
If the instrument is to be shipped to a Tektronix service center for repair, attach a tag showing the following information:
Name of the product owner
Address of the owner
Instrument serial number
A description of the problems encountered and/or service required
When packing an instrument for shipment, use the original packaging. If it is unavailable or not fi t for use, contact your
Tektronix representative to obtain new packaging.
