Figure 3-10.—The LMS-11 Net Display in Summarize Mode.
NCS.— The NCS field allows the operator to
designate the PU number of the NCS. When a
number is not entered in this field, the default address
of 77 is used. It will also be used as the PU number
in the polling display of the status area and in the PU
field of the Net Display.
PU.— The PU field is used by the operator to
designate the PU whose recurring transmission is used
to define a cycle.
The PU field works with the
SUMMARIZE field.
SIDEBAND.— The SIDEBAND field allows the
operator to designate which sideband (USB, LSB, or
DIV) is used for the information displayed.
SUMMARIZE.— The SUMMARIZE field
enables the operator to designate the number of cycles
over which the summary is computed. A “cycle” is
defined as the recurring transmission from the
designated PU.
The data is tabulated after the
specified number of transmissions are received from
the designated PU or after 200 transmissions are
received by any station, whichever occurs first. The
SUMMARIZE field is also used to enable the PU
History mode. The PU History mode is entered when
the operator enters a zero in the summary field. When
the PU History mode is enabled by the operator, the
word HISTORY is added to the Net Display title.
The PU History mode display updates one line of data
immediately after the specified PU has completed its
transmission.
The information displayed by the Net Display
mode is described in the following paragraphs.
PU.— The PU number. The first number listed is
the NCS, which has a default number of 77, or the
address entered in the NCS field. The rest of the PUs
are listed in numerical order.
SIG PWR.— The total signal strength of the 16
tones, measured in dBm. A value of -51 indicates that
no signal was received.
