Micro-Deck Assembly
A7 Micro-Deck Assembly Overview
Self Tests
There is an extensive number of Self Tests for the A7 Micro-Deck assembly. All
the 1100, 1200, 1300, and 1400 series Self Tests are for the A7 Micro-Deck
assembly. See Chapter 4, “Self Test,” for more information on these tests. The
A7 Micro-Deck assembly Self Tests will also be discussed in the “A7
Micro-Deck Assembly Troubleshooting” section later in this chapter.
Calibration Data
Calibration data for the assembly is stored on the A7A1 Microwave ALC
assembly. This is data that was either written to the assembly when the
instrument was produced at the factory or by an adjustment in the
performance verification and adjustment software. Also, replacement A7
Micro-Deck assemblies come from the factory with calibration data stored in
them. See “Calibration Data” in Chapter 3, “Instrument Information and
Calibration Data,” for more information on the instrument calibration data.
Adjustments
There are several adjustments related to the A7 Micro-Deck assembly found in
the performance verification and adjustment software for these instruments,
which will be covered later in this chapter.
For discussion purposes, it is assumed that microwave instruments all
have the option to operate up to 40 GHz (Option 540). The frequency
range of each instrument may vary, but any major difference will be called
out in the different overview sections.
