Definitions
Specification (spec.)
Warranted performance. Specifications include guardbands to account for the
expected statistical performance distribution, measurement uncertainties, and
changes in performance due to environmental conditions. The following conditions must be met:
• FieldFox has been turned on for 10 minutes.
• FieldFox is within its calibration cycle.
• FieldFox remains at a stable surrounding environment temperature (between
-10 to 55 °C) for 90 minutes prior to turn-on and during operation.
Typical (typ.)
Expected performance of an average unit at a stable temperature between 20 °C
to 30 °C for 90 minutes prior to turn-on and during operation; does not include
guardbands. It is not covered by the product warranty. The FieldFox must be
within its calibration cycle.
Nominal (nom.)
A general, descriptive term or design parameter. It is not tested, and not covered
by the product warranty.
Calibration
The process of measuring known standards to characterize an instrument’s
systematic (repeatable) errors.
Corrected (residual)
Indicates performance after error correction (calibration). It is determined by the
quality of calibration standards and how well “known” they are, plus system
repeatability, stability, and noise.

Vector Voltmeter (option 308)
With vector voltmeter mode, you can characterize the difference between two
measurements easily. The zeroing function allows you to create a reference
signal, and characterize the difference between two device measurements.
• 1-port cable trimming - reflection or S11 measurement, magnitude and phase
• 2-port transmission - transmission or S21 measurement, magnitude and phase
• A/B and B/A - ratio of two receivers or channels, magnitude and phase –
Need an external signal generator for the A/B or B/A measurement (must
order option 122).
The results are shown on a large display in digital format. Refer to the network
analyzer section for magnitude and phase accuracy information.
