Key features
The 1.0
mm VNA system R&S
ZNA67EXT can sweep through a frequency range
from 10
MHz to 110
GHz continuously. It.supports two different measurement
modes:
●
Measurements with internal test sets cover a frequency range between
10
MHz and 67
GHz.
The R&S
ZNA67EXT is based on a vector network analyzer R&S
ZNA67.
Connect the DUT to any of the test ports of the R&S
ZNA and measure its
properties as described in this user manual or 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 connec-
tors at the front of the diplexers R&S
ZVA-ZD110. This measurement mode is
described in the present manual.
The following sections describe the external test sets and their connection to the
DUT and to the R&S
ZNA. A typical measurement example is presented in
The measurement mode of each VNA port is selected in the "Converter
Configuration" dialog of the R&S
ZNA GUI (System – [Setup] > "Frequency
Converter" > "Frequency Converter...").
●
"Converter Type" > "None": internal test sets
●
"Converter Type" > "ZNA67EXT-TS": external test sets
●
Selecting another "Converter Type" allows you to measure within the
selected converter's frequency range.
Operation with external test sets
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 fre-
quency converter in the external test set is bypassed. The source signal of the
respective analyzer port is directly fed to the 1
mm test port connector of the
diplexer. The network analyzer measures the a-waves and b-waves from the
Ref Out and Meas Out on the diplexer, respectively. The RF connectors LO
