, if required.
Fluke part number 474908
Approximately 250 µH, see text.
[1] Required only for the optional phase noise test. Refer to the phase noise test section for further details of equipment selection.
[2] Not required for 96040A.
[3] If a 50 Ω Type-N feedthrough termination is unavailable, a Rohde & Schwarz RAD 50 (or equivalent) with a precision 50 Ω Type-N (f) to BNC (m)
adapter may be substituted.
[4] If a 75 Ω Type-N feedthrough termination is unavailable, an Agilent 11094B (or equivalent) with a precision 75 Ω Type-N (f) to BNC (m) adapter may
be substituted.
[5] Not required for 96040A. When used for the Microwave Output Level Accuracy test an equivalent power sensor and corresponding power meter
readout may be substituted. The model NRP-Z55.03 power sensor is supplied as part of the 96000 HF Levelling Kit and 96000SNS Additional Sensor
option.
[6] Not required for 96040A. The model NRP-Z55.03 is supplied as part of the 96000 HF Levelling Kit and 96000SNS Additional Sensor option. When
used for the optional Microwave Output characterization adjustment only compatible Rhode & Schwarz NRP-Z series power sensors of the
appropriate frequency range may be substituted. Refer to chapters 1 and 3 of the 96000 Series Operator’s Manual for details of compatible sensors.
No other substitutions are possible for this adjustment.
[7] May be required for measurements made with the 5790A. Refer to relevant sections of this chapter and section 4-12 of the 5790A Operator’s Manual
for further details.
Typical examples of the AC Measurement Standard listed in Table 3-1 may
exhibit a slight noise floor-related non-linearity on the lowest (2.2 mV) range
which can increase the uncertainty of the tests or adjustments unless a
correction is applied. To determine a 2.2 mV range linearity error, compare the
range with the linearity of the higher ranges where no significant non-linearity
exists.
Fluke Calibration recommends that users familiarize themselves with the
procedures documented in this chapter. The procedures indicate when these
Power Sensor and AC Measurement Standard characteristics must be taken into
account.
Users should also familiarize themselves with the detailed operation of the
equipment listed in Table 3-1 by reading the relevant manufacturer’s instructions
and manuals.
