MTD200 MPEG Test Decoder User Manual
Function Test (Power-on Test)
The unit is powered on by pressing the POWER switch (see Power in Table 3–1
on page 3–2). The MPEG test decoder then performs a built-in test which is
completed after a few seconds. When the boot phase is started, all LEDs on the
front panel light up and a memory test is carried out. If a memory error occurs,
all LEDs will be blinking. If there is no error, the LEDs are switched off and the
boot phase is continued.
The individual steps of the boot phase are indicated by LEDs. The SYNC LED
corresponds to the least significant bit, the PAT LED to the next higher bit, etc. If
an error occurs during the boot phase, the current status indicated by the LED
will be retained (see Table 3–3). Otherwise, the instrument is set to the previous-
ly used instrument status and the status menu is displayed.

The green LEDs next to the front-panel inputs indicate at which input the
instrument expects a signal. See Error Indication in Table 3–1 on page 3–3. If a
valid MPEG-2 signal is applied to the respective input, the instrument must
synchronize to it. When synchronization is completed, the lower (below TS)
green LED lights.
