Status
Selection of the equipment mode of operation. The status can
be set “Local” (all settings included in the software are available,
whereas the telemetry inputs are inhibited) or “Remote” (no
changes may be made from equipment menus, and telemetry
inputs are enabled).
Pg FWD
Selection of the threshold level for “forward power good” signal.
Level is expressed as percentage of set power level. The activation
of power good is on when
PTX-DDS
actual output power exceeds
this percentage of nominal power. For example: assuming that
power set in the default menu is 70% of machine rated power
(i.e.:
PTX100DDS
70% x 100W = 70W) and PG1 is set to 80%
in the menu under discussion, the PG1 output at PIN 9 of the
telemetry card will be on when actual output power exceeds (i.e.:
PTX100DDS
80% x 70W = 56W).
Pg RFL
Selection of the threshold level for “reflected power good” signal.
Level is expressed as percentage of set power level. The activation
of power good is on when
PTX-DDS
actual output power exceeds
this percentage of nominal power. Pg RFL operates on the same
logic as Pg FWD.
RLY1

15).
RLY2
Visualization of the “Relay 2” status on the DB15 interface (Pin
7).
