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
conditions.
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 product warranty.
Supplemental information: May include typical, nominal, or characteristic values.
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 (calibration). It is determined by the quality of calibration standards and
how well “known” they are, plus system repeatability, stability, and noise.
Uncorrected (raw) performance: Indicates instrument
performance without error correction. The uncorrected (raw) performance affects the stability of a
calibration.
System performance: Performance of a complete
multiport test system, which includes an 87075C
test set and a 75-Ohm 8712ET/ES or 8714ET/ES
network analyzer.
Test Set Cal: The calibration of a multiport test system, requiring the connection of known calibration
standards to all of the ports that will be used for
measurements.
SelfCal: An automated system calibration that uses
calibration 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 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 a 75-Ohm 8712ES or 8714ES
network analyzer 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. 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.

Agilent 85036B/E Type-N calibration kit
1. These specifications are valid for reflection (one-port) and transmission
(enhanced-response) Test Set Cals, and 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 a
75-Ohm 8712ET, 8712ES, 8714ET, or 8714ES network analyzer 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 current temperature is within 25 °C ± 5 °C, and within ± 1 °C of the
most recent SelfCal.
