Features & Benefits
family comprises the five Vector Network Analyzers ZVRL, ZVRE and ZVR as well
as ZVCE and ZVC which extend the frequency range to 8 GHz. All models are
compact instruments with integrated generator, test set and receiver, each
tailored to a different field of application. All analyzers can be subsequently
upgraded to the higher-class models.
ZVRE and ZVCE : the economy models
test set of these models comprises two SWR bridges (ZVRE) or directional
couplers (ZVCE), an RF switch, two measurement channels and one reference
channel. They measure the magnitude and phase of all four S-parameters of a
DUT, allow a full two-port calibration (TOSM) and have an exceptionally high
accuracy and wide dynamic range.
ZVR and ZVC : the universal models
and ZVC comprise a test set with two SWR bridges (ZVR) or directional couplers
(ZVC), an RF switch, two measurement channels and - unlike ZVRE and ZVCE - two
reference channels. With this configuration a variety of novel calibration
procedures, eg TNA, can be performed, which considerably improve the accuracy
particularly in non-coaxial applications. ZVR and ZVC are the allrounders of
the family and suitable for applications in R&D and production no matter
network analyzers can be provided with different test set options so that an
optimally configured test setup is available to suit the applications.
For the 4 GHz analyzers
"active" or "passive" test sets with a characteristic
impedance of 50 W or 75 W are available. A 50 W passive test set is standard
equipment. With active test sets, the DUT can be biased directly via the inner
conductor of the test port. The 8 GHz models ZVCE and ZVC are always equipped
with 50 W active test sets. Depending on the model, the test sets comprise one or
two power splitters, an electronic switch and one or two SWR bridges or
Additional step attenuators (0 dB to 70 dB, components
marked red in the drawings below) can be inserted into the generator paths and
the two measurement channels to extend the power range of the receivers to +27
dBm and to lower minimum output power to -95 dBm. When the test sets are fitted
with attenuators and the External Measurements option (components marked green
in the drawings below), generator and receiver can be alternatively switched to
three ports on the front panel (OUTPUT a1, INPUT b1, INPUT b2).
output power, sensitivity and dynamic range, and measurements down to 10 Hz can
be performed with the 4 GHz models. In addition, the flexibility on external
test sets, e.g. using an external pre-amplifier, is enhanced. The Reference
Channel Ports (components marked blue in the drawings below) allow to feed the
signal for the reference channel a1 from outside. This feature facilitates e.g.
phase measurements on frequency converting devices. The test ports are fitted
with female N connectors.
