Lesson 2 – TIA Setup
TIA Measurements
In addition to the pure time interval measurements, the TIA can
perform calculations on the measured values, for example to
determine jitter. A calculated result can be retrieved, like a direct
time interval measurement result, with a test method. This is
described in the next lesson.
For the frequency measurement, the TIA measures the signal
period and then automatically calculates the signal frequency from
it.
Arming Settings
Triggering of the TIA is different from the other analog modules.
When the TIA receives the trigger signal, it does not start the
measurement immediately, like the other analog modules do.
The measurement starts, when the appropriate edge to start the
measurement from is detected.
This is why the triggering of the TIA is also called Arming, and
the trigger signal is also called arming signal.
For example, when doing a PW++ measurement on channel 1, the
measurement starts with the first rising edge on channel 1 after
the arming signal has been received.
The TIA setup area of the Hardware Settings page lets you make
all settings to define the arming for a TIA test.
