Vector Network Analyzer R&S ZVA110
The R&S ZVA-Z110 vector network analyzer supports two essentially different measurement modes:
 Measurements with internal test sets cover a frequency range between 10 MHz and approx. 67
GHz. The R&S ZVA-Z110 is based on a four-port R&S ZVA67 vector network analyzer. The DUT
can be connected to any of the four test ports of the R&S ZVA67. One to four-port measurements
can be performed as described in this help system.
 Measurements with external test sets cover an extended frequency range between 10 MHz and
110 GHz. The DUT is connected to the 1 mm connector(s) at the front of the diplexers R&S ZVA-
ZD110. This measurement mode is described in the following sections.
For a general introduction to the R&S ZVA110 refer to the Getting Started guide R&S ZVA110, Broadband
Measurements Using the 1 mm External Test Sets, which is posted on the R&S ZVA110 product pages on
the internet. Please note in particular the safety instructions in the Getting Started guide.
The R&S ZVA110 is delivered with all measurement equipment needed. An additional 1 mm calibration kit
is required for calibration.
Test Setup and Principle of the Measurement
The R&S ZVA110 is delivered with two fully assembled external test sets, each consisting of a diplexer
R&S ZVA-ZD110 and a frequency converter WR10 R&S ZVA-Z110E. The connection for a single external
test set is shown below; for details refer to the Getting Started guide R&S ZVA110.
The external test sets enable a frequency range between 10 MHz and 110 GHz. The analyzer combines
two different measurement methods to achieve this extended range.
 At frequencies below approx. 67 GHz (i.e. in "low frequency" mode), the frequency converter in
the external test set is bypassed. The source signals from test ports PORT 1 / 2 of the vector
network analyzer unit are directly fed to the 1 mm test port connectors of the diplexers. The
network analyzer measures the a-waves (reference channels) from REF OUT and the b-waves
(measurement channels) from MEAS OUT on the diplexers. The connector groups PORT 3 / 4 on
the network analyzer and the RF connectors LO IN, RF IN, REF OUT, MEAS OUT on the rear
panel of the converters are not used.
 To achieve frequencies above approx. 67 GHz (i.e. to measure in "high frequency" mode), the
source signals from test ports PORT 1 / 2 of the network analyzer are fed to the frequency
converters; the converted signals are routed to the 1 mm test port connectors of the diplexers.
The frequency converters use frequency multipliers to transform the source signal into a high-
