4.3.5.4 Remote Selection of Active IPA
Module or PA (if applicable)
If the transmitter is configured for dual IPA
module (V10/V7.5 only) or dual PA
(V5/V3.5 only) operation, verify IPA module
(or PA) A or B can be selected from a
remote location:
NOTE
For V10/V7.5, the remote selection of the
active IPA module is ganged together with
the remote selection of the active IPA
power supply.
(a) Verify 4.3.5.1 is complete.
(b) Remotely select IPA module B (V10/
V7.5) or PA B (dual PA V5/V3.5) as the
active intermediate RF drive source by
activating an input to the remote
interface PWB's
EXT IPA B terminal(s)
[TB3-9 (+)/TB3-10 (-)].
(c) The RF output, as displayed by the
RF
KILOWATTS meter and GUI, will
momentarily go to 0 W and then return
to rated power.
(d) The GUI will indicate IPA B (and IPA
PS B for the V10/V7.5) is active. The
remote interface PWB’s
IPA STATUS
terminal (TB1-16) will be a current-
sink-to-ground. For V10/V7.5, the
IPA
PS Status output (J4-23) will also be a
current-sink-to-ground.
(e) Remotely select IPA module A (V10/
V7.5) or PA A (dual PA V5/V3.5) as the
active intermediate RF drive source by
activating an input to the remote
interface PWB's
EXT IPA A terminal(s)
[TB3-7 (+)/TB3-8 (-)].
(f) The RF output, as displayed by the
RF
KILOWATTS meter and GUI, will
momentarily go to 0 W and then return
to rated power.
(g) The GUI will indicate that IPA A is
active. The remote interface PWB’s
IPA STATUS terminal (TB1-16) will be
an open-collector. For V10/V7.5
transmitters, the
IPA PS Status output
(J4-23) will also be an open-collector.
4.3.5.5 Remote Selection of Active IPA
Power Supply (if applicable)
For V5/V3.5 only: If the V5/V3.5 is
configured for dual IPA power supply
module operation, verify IPA power supply
(PS) module A or B can be selected from a
remote location:
NOTE
For V10/V7.5, the IPA power supply is
ganged together with the selection of the
active IPA module (see 4.3.5.4).
(a) Verify 4.3.5.1 is complete.
(b) Remotely select IPA PS B as the
active IPA PS by activating an input to
the remote interface PWB's
Ext IPA PS
B pin(s) [J6-29 (+)/ J6-30 (-)].
(c) The RF output, as displayed by the
RF
KILOWATTS meter and GUI, will
momentarily go to 0 W and then return
to rated power.
(d) The GUI will indicate IPA PS B is
active. The remote interface PWB’s
IPA PS Status output (J4-23) will be a
current-sink-to-ground.
(e) Remotely select IPA PS A as the
active IPA PS by activating an input to
the remote interface PWB's
Ext IPA PS
A pin(s) [J6-27 (+)/ J6-28 (-)].
(f) The RF output, as displayed by the
RF
KILOWATTS meter and GUI, will
momentarily go to 0 W and then return
to rated power.
(g) The GUI will indicate that IPA PS A is
active. The remote interface PWB’s
IPA PS Status output (J4-23) will be
open collector.
