Time Tag Clock Source
The TIMETAG command selects the source and frequency for the
analyzer time tag clock. Entering this command with no parameter
values brings up the time tag window, from which you can select a
frequency or a source. If you select a frequency, the system uses an
internal source of the frequency chosen. If you select a source, the
system prompts for an appropriate frequency value.
If you select the external source, connect logic clip TT_OSC (white) of
the pod B cable to the external clock source. (The pod B connector is the
closest to the front of the station module.)
When using the logic clip cables, always attach the black clip to ground.
Syntax:
TIMETAG [[< source >] [< rate >]]
Where:
< source > The source for the analyzer timetag clock. The clock
can be provided from one of four sources:
1. Internal (MMDS platform board), programmable, external or
emulation module. With no source specified, the internal source is
understood.
To specify other possible clock sources, use the following:
2. EM Use the bus clock of the MCU being emulated
3. PR Use a programmable clock in the range of 50 to 50,000 Hz
4. EX Use an external clock provided through the TT_OSC logic
clip (white) of pod B
