Introduction
All specifications and characteristics apply over a
25 °C ± 5 °C range (unless otherwise stated) and
30 minutes after the instrument has been turned on.
Definitions
Specification:
Warranted performance. Specifications include
guardbands to account for the expected statistical
distribution, measurement uncertainties, and
changes in performance due to environmental con-
ditions.
Characteristic:
A performance parameter that the product is
expected to meet before it leaves the factory, but is
not verified in the field and is not covered by the
product warranty. A characteristic includes the
same guardbands as a specification.
Typical:
Expected performance of an average unit. A typical
does not include guardbands. It is not covered by
the product warranty.
Nominal:
A general, descriptive term that does not imply a
level of performance. It is not covered by the prod-
uct warranty.
Supplemental information:
May include typical, nominal, or characteristic val-
ues.
Calibration:
The process of measuring known standards from a
calibration kit to characterize the systematic
(repeatable) errors of a network analyzer.

Corrected (residual) performance:
Indicates performance after error correction (cali-
bration). It is determined by the quality of calibra-
tion standards and how well “known” they are,
plus system repeatability, stability, and noise.
Uncorrected (raw) performance:
Indicates instrument performance without error
correction. The uncorrected performance affects
the stability of a calibration.
System performance:
Performance of a complete multiport test system,
which includes an 87050E test set and an 8712ET/
ES or 8714ET/ES network analyzer.
Test Set Cal:
The calibration of a multiport test system, requir-
ing the connection of known calibration standards
to all of the ports that will be used for measure-
ments.
SelfCal:
An automated system calibration that uses calibra-
tion standards internal to the test set and the most
recent Test Set Cal data to calibrate the test system.
Environmental specifications:
Environmental specifications bound the external
conditions for which the specifications are valid.
The environmental specifications also bound the
external conditions the test set may be subject to
without permanently affecting performance or
causing physical damage.

1. These specifications and supplementals apply under the following conditions: measurement uses the “Fine” (15 Hz) bandwidth, no averaging, and isolation cal “on”; Test Set
Cals use the “Fine” (15 Hz) bandwidth, 16 averages, and assume an isolation calibration has been performed; the test set must be used with an 8712ES or 8714ES network ana-
lyzer with firmware revision E.06.00 or later; the test set and the analyzer must have had their performance verified within the last year; both instruments must have warmed up
for at least 30 minutes after turn-on; measurements are made at an environmental temperature of 25 °C ± 5 °C and within ± 1 °C of the last valid Test Set Cal.
2. Corrected system performance is changed to typical when the current temperature has drifted beyond ± 1 °C of the last valid Test Set Cal. Typicals are valid only when the cur-
rent temperature is within 25 °C ± 5 °C, and within ± 1 °C of the most recent SelfCal.
3. These uncertainty curves only include the effects of the test port(s) within the measurement path. The effect of the uncorrected match of test ports outside the measurement
path is ignored, and is dependent on the isolation between the ports of the DUT that are within the measurement path and ports of the DUT that are outside the measurement
path.
