Built-in PC
ANT-20SE uses a Pentium PC as internal controller so that standard
PC applications can also be run on the instrument.

Power outage function
In the event of an AC line power failure during a measurement,
ANT-20SE saves all data.
As soon as the AC line voltage is reestablished, the measurement is
resumed. Previous results are retained and the time of the power failure
is recorded along with other events.

Byte capture TOH and POH
To analyze the TOH/POH functions, it is necessary to capture
individual bytes vs. time, allowing detection of errors or short-term
changes with frame level precision.
The Capture function is started by a selectable trigger.
Values for a selected byte are stored and can be accessed subsequently
in a table of values.
Particularly in capturing the APS sequences, the bytes (K1, K2) are
displayed as an abbreviation of the standard commands.
The function also allows recording of the N1 or N2 bytes
for evaluation of ªTandem Connectionº information.
H4 sequences can also be analyzed very easily.
The results can be printed or exported.

APS time measurement
In synchronous networks, a defined maximum switch-over time is
necessary for the traffic in case of a fault.
To verify compliance with this requirement, the ANT-20SE measures
the switch-over time with 1 ms resolution.
The result can be printed.
