PTDavg_port:
Description: Switch to averaged PTD port. Changes the current command port (1700)
connection into a ptdavg port (2100) connection. Hitting the <return> key will switch the
connection back into a command port connection.
The ptdavg port is only available when the 4393A PPS measurement card is installed in the
system. The 4393A card accepts an input PPS on four different inputs and measures the
time difference between the input PPS and the internal system PPS. Port 2101 provides the
raw measurement data for every PPS received and the ptdavg port (2100) averages the raw
measurements over the specified interval.
The input channels on the 4393A are identified by the slot that the 4393A is installed in and
the port number of the 4393A.
The slots in the rear of the system are numbered as follows (looking at the rear panel):
[Slot 1] [Slot 3] [Slot 5]
[Slot 2] [Slot 4] [Slot 6]
Thus, if the PPS input is provided on input 3 of the 4393A card installed in slot 4 it will be
identified as 'Ch43' on the ptdavg port.
