Getting Started

Product Description

The WFM 601i is capable of measuring and monitoring 4:2:2 component serial digital. It displays the video signal in the familiar component analog representation, either paraded or overlaid. An equivalent time sampler is incorporated to show the eye pattern of the serial signal. Data integrity is verified by the EDH (Error Detection and Handling) system, and by a suite of serial digital format checks.

Installation

Packaging

At installation time, save the shipping carton and packing materials (including anti-static bag) in case it becomes necessary to ship the instrument to a Tektronix Service Center for service or repair.

Repackaging for Shipment If it becomes necessary to ship the instrument to a Tektronix Service Center for service or repair, follow these instructions for repackaging:

1.Attach a tag to the instrument showing: the owner, complete address and phone number of someone at your firm who can be contacted, the instrument serial number and a description of the required service.

2.Repackage the instrument in the original packaging materials. If the original packaging materials are not available, follow these directions:

a.Obtain a carton of corrugated cardboard having inside dimensions six or more inches greater than the dimensions of the instrument. Use a shipping carton that has a test strength of at least 275 pounds.

b.Surround the instrument with a protective bag (anti-static preferred). For instruments which are not in a cabinet, wrap a cardboard piece around the bagged instrument to protect components.

c.Pack dunnage or urethane foam between the instrument and the carton. If using Styrofoam kernels, overfill the box and compress by closing the lid. There should be three inches of tightly packed cushioning on all sides of the instrument.

3.Seal the carton with shipping tape, industrial stapler, or both.

Internal Jumper

Jumper J6 changes the rear panel Serial Out signal amplitude. Normal Output amplitude is 800 mV, but some equipment may work best at 740 mV. Jumper J6, located on the Deserializer board, can be changed so that the Serial Output is 740 mV. Table 1±1 gives the jumper settings.

Looking at the front of the WFM 601i, the Deserializer board is located on the left hand side, near the rear instrument.

Cabinets The cabinets available for this instrument not only provide necessary shielding, and protection against accidental electrical shock, but also provide internal circuitry with protection against build up of dust. A supply of filtered, cooling air is provided from the rear panel and exits through the cabinet vent holes. Operation in air flow restricted environments may lead to excessive heat build up.

All qualification testing for the WFM 601i was performed in a 1700F00 cabinet. To guarantee compliance with specifications, the instrument should be operated in a cabinet. The plain cabinet, 1700F00, is shown in Figure 1-1.

NOTE. To meet EMI emission specifications, the WFM 601i must be installed in a Tektronix 1700F00, 1700F02, or 1700F05 enclosure. The enclosure front edges must securely contact the instrument's conductive front bezel on all four sides.

The optional 1700F00 cabinet is the basic element for all of the cabinets that fit this instrument. The 1700F02 Portable carrying case is an enhanced version of

Installation

Cabinetizing

Do not attempt to carry a cabinetized instrument without installing the mounting screws. Without the mounting screws there is nothing to hold the instrument in the cabinet if it is tipped forward.

The instrument is secured to the cabinet by two 6-32 Pozidriver screws, located in the upper corners of the rear panel. See Figure 1-3.

Cabinet Mounting Screws

Rack Adapter The optional 1700F05 side-by-side rack adapter, shown in Figure 1-4, consists of two attached cabinets. It can be used to mount the WFM601i and another half-rack width instrument, such as an analog component monitor (Tektronix WFM300A or 1760-Series), in a standard 19-inch rack.

Installation

If only one side of the rack adapter is used, a 1700F06 Blank Panel can be inserted in the unused section. See Figure 1-5. The rack adapter and panel are available through your local Tektronix field office or representative.

When only one instrument is mounted in the side-by-side adaptor an accessory drawer (1700F07) can be installed in the blank side of the cabinet. See Figure 1-6.

Installation

To mount the WFM601i safely, attach it to a shelf strong enough to hold its weight. Install the mounting screws through the four 0.156-inch diameter holes in the bottom of the 1700F00 cabinet. See Figure 1-7.

For Flush Front Panel: Cut hole the same size as the monitor front molding to allow the monitor front panel to align with the custom panel surface.

Requires four 0.156º holes below the 1700F00 cabinet to secure the instrument to the shelf.

For Protruding Front Molding: Cut hole in panel the same size as the opening in the monitor cabinet to allow the front panel molding to cover the hole.
