Preface Preface This is the service manual for the MTX100B MPEG Recorder and Player. This manual contains information needed to service an MTX100B to the module level. Manual Structure This manual is divided into sections, such as Theory of Operation and Maintenance.
Page 16
Modules Throughout this manual, any replaceable component, assembly, or part of the MTX100B is referred to generically as a module. In general, a module is an assembly (like a circuit board), rather than a component (like a resistor or an integrated circuit).
MPEG Recorder and Player, as well as general information critical to safe and effective servicing. To prevent personal injury or damage to the MTX100B, consider the following before beginning the service: The procedures in this manual should be performed only by a qualified service person.

Theory of Operation This section describes the basic operation of the major circuit blocks or modules in the MTX100B. The Diagrams section includes a block diagram and an interconnect diagram. A12 Main Board The A12 Main board consists of the following blocks: PCI Interface The PCI interface consists of a PCI target and a PCI master.
FIFO empty, Record FIFO full, external trigger, 10 Hz, Playout DMA transfer finished, and Record DMA transfer finished. These signals can be disabled by the MTX100B application software. At power on, all interruptions are disabled. TS Clock Generator The TS clock generator consists of a VCO (Voltage Control Oscillator), a phase detector, and a frequency divider.
But R302 is not installed, so the adjustment has no effect and the backlight is at maximum brightness. USB Ports There are two USB connectors on the board that are connected through a cable to the USB 2.0 interface connector on the CPU board. MTX100B MPEG Recorder and Player 2–3...
It is possible to reconfigure the received data as a serial data string from the intermittently transmitted data. When the data rate from the MTX100B storage (hard disk or RAM) is lower than 216 Mbps, it is possible to select whether to sparsely output all the data or to output the data on a packet-by-packet basis as the ASI output.
Bit is detected. The data rate of FIFO input port is equal to the data transfer rate of the MTX100B, and that of output port is 216 Mbps (with the clock of 27 MHz), which is used for the ASI output.

You may also refer to the MTS100B Specifications and Performance Verification manual, which contains procedures that may be useful in isolating problems to modules by testing the MTX100B performance. See the MTX100B Specifications and Performance Verification Technical Reference, available on the Tektronix Web site at www.tektronix.com/manuals.
MTX100B is used. General Care The cabinet helps keep dust out of the MTX100B, and is needed to meet EMI and cooling requirements. The cabinet should be in place when operating the MTX100B. The front cover protects the front panel and display from dust and damage.
Cleaning Procedure – Exterior. To clean the MTX100B exterior, perform the following steps: 1. Remove loose dust on the outside of the MTX100B with a lint free cloth. 2. Remove remaining dirt with a lint free cloth dampened in a general purpose detergent-and-water solution.
Maintenance Inspect the internal portions of the MTX100B before damage and wear, using the following table as a guide. Defects found should be repaired immediately. CAUTION. To prevent damage from electrical arcing, ensure that circuit boards and components are dry before applying power to the MTX100B.
Page 41
If, after performing steps 1 and 2, a module is clean upon inspection, skip the remaining steps. 3. If steps 1 and 2 do not remove all the dust or dirt, the MTX100B may be spray washed using a solution of ethyl alcohol by performing steps 4 through 8.
Before performing this or any other procedure in this manual, read the Safety Summary found at the beginning of this manual. Also, to prevent possible damage to components of the MTX100B, read Preventing ESD in this section.
