This is a subset of technical specifications for the N5230A Option 240 and 245
network analyzer.

To view or print the N5230A technical specifications, visit our web site at

www.agilent.com/find/pnal

This N5230A document provides technical specifications for the following calibration
kit and ECal module only: 85052B and N4691A. Please download our free Uncertainty
Calculator from www.agilent.com/find/na_calculator to generate the curves for
your calibration kit and PNA setup.

Definitions

All specifications and characteristics apply over a 25 °C ±5 °C range
(unless otherwise stated) and 90 minutes after the instrument has been
turned on.

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.

Characteristic (char.): A performance parameter that the product is expected
to meet before it leaves the factory, but that is not verified in the field and is
not covered by the product warranty. A characteristic includes the same
guardbands as a specification.

Typical (typ.): Expected performance of an average unit which does not include
guardbands. It is not covered by the product warranty.

Nominal (nom.): A general, descriptive term that does not imply a level of
performance. It is not covered by the product warranty.

Calibration: The process of measuring known standards to characterize a
network analyzer'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.

Uncorrected (raw): Indicates instrument performance without error correction.
The uncorrected performance affects the stability of a calibration.

Standard: When referring to the analyzer, this includes no options unless
noted otherwise.

Corrected System Performance

The specifications in this section apply for measurements made with the
N5230A Options 240 and 245 analyzer with the following conditions:

• 10 Hz IF bandwidth

• No averaging applied to data

• Isolation calibration with an averaging factor of 8

1. The system dynamic range is calculated as the difference between the noise floor and the specified

source maximum output power. The effective dynamic range must take measurement uncertainties
and interfering signals into account.

2. May be degraded by 10 dB at particular frequencies (multiples of 5 MHz) below 500 MHz due to

spurious receiver residuals. Methods are available to regain the full dynamic range.

1. The direct receiver access input extended dynamic range is calculated as the difference between

the direct receiver access input noise floor and the source maximum output power. The effective
dynamic range must take measurement uncertainties and interfering signals into account. This
set-up should only be used when the receiver input will never exceed its compression or damage
level. When the analyzer is in segment sweep mode, it can have predefined frequency segments
which will output a higher power level when the extended dynamic range is required (i.e. devices
with high insertion loss), and reduced power when receiver compression or damage may
occur (i.e. devices with low insertion loss). The extended range is only available in one-path
transmission measurements.

2. May be degraded by 10 dB at particular frequencies (multiples of 5 MHz) below 500 MHz due to

spurious receiver residuals. Methods are available to regain the full dynamic range.

Maximum delay Limited to measuring no more than 180° of

phase change within the minimum aperture

The following graph shows characteristic group delay accuracy with full 2-port calibration and
a 10 Hz IF bandwidth. Insertion loss is assumed to be < 2 dB and electrical length to be ten meters.

For any S

In general, the following formula can be used to determine the accuracy, in seconds, of specific
group delay measurement:

Depending on the aperture and device length, the phase accuracy used is either incremental
