Chapter 3 Replacing Assemblies
To Remove a 6.0 GHz or 15.0 GHz Microwave Channel Assembly
(Options 106/115)
180 Assembly-Level Service Guide
NOTE (Front Panel Input Channel Connector) If the semi-rigid cable
connectors do not line up exactly without distorting the cable,
turn the chassis over and, through the open area provided, use a
5/16" wrench to loosen the SMA connector on the semi-rigid cable
where it connects to the front panel and gently re-position the
cable until it is positioned to connect the assembly to the front
panel, with no stress on either end of the semi-rigid cable.
NOTE (Rear Panel Input Channel Connector) If the semi-rigid cable
connectors do not line up exactly without distorting the cable,
loosen the 5/16" nut on the outside rear panel SMA connector and
gently re-position the cable until it is positioned to connect the
assembly to the rear panel, with no stress on either end of the
semi-rigid cable.
3 Use a 5/16" open-end wrench to secure the SMA connectors at each
end of the semi-rigid cable. Do not overtighten.
4 Install the two flathead screws through the holes in the left-hand
aluminum side panel into the embedded nuts on the bracket of
the Channel 2 assembly and tighten.
5 Tighten the T20 TORX screw.
NOTE After installing either the 6 GHz or the 15 GHz Microwave
Channel assembly, perform the calibration procedure in Chapter
2 for that assembly. For the 53210A Counter, the assembly is
Channel 2. For the 53220A and 53230A Counters, the assembly is
Channel 3.
