Telemetry Blocks Quick Look

Telemetry Blocks are displayed back to back on the Quick Look window.
Offset 0000 marks the beginning of a Telemetry Block.
Telemetry Blocks are structured as follows (see section 3.4.11 : for more details):
Telemetry frame:
Synchronization Word + telemetry frame (if frame synchronizer ON) or raw data (if frame
synchronizer OFF). At the end of the frame, spare bytes for 8 bytes alignment (if required). These
added spare bytes can have any values.
TM Block time tag (8 bytes):
Bits D0-31 (offset N): number of seconds elapsed since January 1st, 00:00:00 of current year
Bits D32-63 (offset N+1): number of microseconds in the current second
Both 32-bit fields are integers coded in hexadecimal form.
The time tag can be disabled by set-up (refer to "Real Time Frame" window: disable frame datation).
Telemetry Block status (8 bytes): the Telemetry Block status is captured and displayed in this field
only if the frame synchronizer is ON.
Optional spare field (from 0 to 8 words of 8 bytes): the number of spare data words (64 bit words) is
selected in the "Real Time Frame" Window. These data words are filled with "00000000" values.
