Table 2-1 Required Equipment for Adjustments
1. An 85032B Option 001 is a subset of the standard 85032B. This option eliminates four 7-mm
adapters that are not needed, resulting in a significant cost savings.
2. The required attenuators depend on the firmware revision of the analyzer. The attenuators
listed above apply to all versions of firmware.
3. The frequency counter is useful when very accurate frequency measurements are needed. How-
ever, if you are using a synthesized spectrum analyzer, the frequency can be measured by using
the spectrum analyzer. Note that the frequency measurement using a spectrum analyzer will
not be quite as accurate as a frequency counter, but is sufficient in most cases. (An 8560 series
spectrum analyzer may be used.)
