DHCT counts per QPSK
The data in the DHCT counts per QPSK field lists the number of DHCTs that
communicate with each QPSK modulator and demodulator in the system. In
addition, under the Node Set Name / HCT Count subheading, the field lists all of
the defined node sets on the system, as well as the number of DHCTs assigned to
each node set.

Mod Slot Tolerance
The data in the Mod Slot Tolerance field confirms that the slot tolerances of all QPSK
modulators is 2.2 microseconds.

Important: If the system reports a QPSK modulator with a slot tolerance that is not
2.2 microseconds, change the slot tolerance for that modulator and then reset the
modulator.
