O = Open
The O standard is a one-port standard. It realizes total reflection with a magnitude of one in the ideal case and a phase of approx. 0°. The phase response
versus frequency must be accurately known to the analyzer (coefficients Ci). A
frequency-dependent increase of the return loss can be considered by the
analyzer. The electrical length of the O standard may be different from zero
and must be exactly known.
S = Short
The S standard is a one-port standard. It realizes total reflection with a magnitude of one in the ideal case and a phase of approx.180° at short-circuit plane
(coefficients Li). A frequency-dependent increase of the return loss can be
considered by the analyzer. The electrical length of the S standard may differ
from zero and must be known. It causes a length-proportional frequency
dependence of the phase.
M = Match
The M standard is a one-port standard which in the ideal case realizes a zeroreflection termination for the reference impedance (mostly 50 Ω). A sliding
match is often used at high frequencies because it yields higher effective directivities than fixed loads.
R = Reflect
The R standard is a one-port standard. In contrast to the M standard it features
high reflection which may assume any unknown value. It must be known
however whether the reflect approaches an open or a short-circuit. Since line
transformation must be expected because of the electrical length of the R standard, the electrical length has to be approximately known.
L = Line
The L standard is a two-port standard. It establishes an almost perfectly
matched connection between the two test ports and defines the reference impedance. A frequency-dependent attenuation caused by the L standard can be
considered by the analyzer. The L standard must have an electrical length that
differs from that of the T standard, but the difference should not amount to an
integer multiple of half the wavelength (singularity).
N = Network
The N standard is a two-port standard featuring symmetrical reflection which
may assume any value other than zero but has to be identical at both ports.
Same as with the R standard it must be known whether the reflection approaches an open or a short-circuit. Transmission of the N standard is arbitrary, need
not be known and may vary arbitrarily versus frequency. In the extreme case it
may even be one or zero.
A = Attenuator
The A standard is a two-port standard. It has to be well matched and may feature any unknown loss different to that of the T standard.
TOM-X (X = crosstalk) is an extension of the TOM method. It considers all
possible crosstalk between the four receiver channels (full model). Since this
technique does not use approximations, it is particularly effective in the elimination of crosstalk and thus in increasing the effective dynamic range of the
system. This method however needs a higher effort. Alternatively, the automatic
calibration procedure AutoKal (Rohde&Schwarz patent) is available as an
option for ZVRE, ZVR, ZVCE and ZVC.

System error correction techniques
All analyzer models offer simple normalizations for reflection and transmission
measurements, one-path two-port calibration and a full one-port calibration
(3-term). Full two-port calibration TOSM (12-term) can be carried out with
models ZVRE and ZVCE. ZVR and ZVC offer the greatest variety of modern
system error correction methods. Apart from the techniques already mentioned,
the following full two-port procedures are available: TOM, TRM, TRL, TNA,
TOM-X (15-term). The names indicate the standards used for calibration:
T = Through
The T standard is a two-port standard which establishes a direct low-loss
connection between the two test ports. A frequency-dependent attenuation can
also be taken into account by the analyzer. The standard has to be well matched
and may have any electrical length, which has to be exactly known (compare
L standard).

SMA connector pair to connect an external reference mixer for measurements
on frequency-converting DUTs.
Other optional interfaces
(e.g. LAN Ethernet) are available and will be specified on request.
Specifications of options
External Measurements option
This option adds three additional front-panel connectors, OUTPUT a1,
INPUT b1 and INPUT b2, to the basic unit (ZVRL: PORT 2 is used as INPUT b2)
to provide direct access to the generator output and the two receiver inputs.
Internal SWR bridges or couplers are bypassed. As a result, frequency range
(with ZVRL, ZVRE and ZVR towards the lower end), output power and sensitivity
of the network analyzer increase.

Power Calibration option
With this firmware option the analyzer power can be calibrated precisely. The
source power (additional power meter e.g. NRVD, NRVS or NRV from
Rohde&Schwarz required) as well as the absolute power measurement of the
receiver input signals (including a1 EXT) can be calibrated.
AutoKal option
The AutoKal module is used for automatic analyzer calibration and employs a
patented calibration method. It is connected to PORT1 and PORT 2 of the
network analyzer and remains connected during all calibrations and measurements. It is, therefore, an integral part of the analyzer system and its two type
N jacks are used as PORT1 and PORT 2. The DUT can be connected to these
ports directly or via a test cable.

Time Domain option

3-Port Adapter option
This option adds a third port to the two ports of the network analyzer. The option
contains an electronic switch for connecting PORT1 of the analyzer alternatively to PORT1or PORT3 of the 3-Port Adapter. PORT2 of the analyzer is directly
connected to PORT2 of the option and is not switched.

4-Port Adapter option
This option adds two further ports to the two ports of the network analyzer. It comes
in two models (02 and 03), which provide different switching functions and are
thus particularly suitable for specific 4-port DUTs.
Model 02 comprises two separate switches (SPDT). The first connects PORT1
of the analyzer alternately to PORT1 or PORT3 of the 4-Port Adapter. The
second connects PORT2 of the network analyzer alternately to PORT2 or
PORT4 of the 4-Port Adapter.
Model 03 connects PORT1 of the network analyzer directly to PORT1of the
4-Port Adapter while PORT2 of the analyzer can be switched to one of the
remaining three ports of the 4-Port Adapter.

Virtual Embedding Networks option
This option allows measured networks or simulated networks from a CAD
program to be considered in the measurement results. Mismatched DUTs such
as SAW filters can be matched virtually without any additional hardware being
required. Furthermore, the effect of real embedding networks like test fixtures
can be eliminated by calculation complementary to calibration procedures.
Increased Output Power for Port 1 option
This option increases the output power at PORT1 and OUTPUT a1. The maximum
power depends on the instrument model.
