Attention!
Please observe the safety instructions on the technical information
provided with the calibration unit to avoid any damage to the unit
and the network analyzer. Safety-related aspects of ZV-Z51
connection and operation are also reported in the sections below.
Connecting the Calibration Unit to the Network Analyzer
The calibration units provide the following connectors:
Calibration units R&S ZV-Z51
•
A USB type B connector at the rear is used to power-supply and control the unit. A USB cable
for connection to the network analyzer is provided with the calibration unit.
•
The RF connectors numbered 1 to 4 are to be connected to the corresponding test ports of the
analyzer. The connector type is either type N (f) or 3.5 mm (f) for all four connectors.
Calibration units R&S ZV-Z58
•
A USB type B connector at the front is used to control the unit. A USB cable for connection to
the network analyzer is provided with the calibration unit.
•
The RF connectors numbered 1 to 8 are to be connected to the corresponding test ports of the
analyzer. The connector type is type N (f) for all connectors.
To connect the unit...
1. Switch on and start-up your network analyzer.
2. To protect your equipment against ESD damage use the wrist strap and grounding cord supplied
with the instrument and connect yourself to the GND connector at the front panel.
3. Connect the USB type A connector of the USB cable to any of the USB type A connectors on the
front or rear panel of the analyzer. Connect the USB type B connector of the USB cable to the USB
type B connector of the calibration unit. You can also connect the unit before switching on the
analyzer.
4. Wait until the operating system has recognized and initialized the new hardware. When the unit is
connected for the first time, this may take longer than in normal use.
The unit is ready to be used, see Performing an Automatic Calibration below.
Notes:
•
The calibration unit is intended for direct connection to ZVA
network analyzers following the procedure described above. You
can also connect the unit before switching on the analyzer. Do
not connect the unit to other USB hosts, e.g. a PC, or insert any
USB hubs between the analyzer and the unit, as this may cause
damage to the unit or the host.
•
Connect only one calibration unit at a time. You can use the three
remaining USB ports of the analyzer to connect other devices
(mouse, USB memory stick etc.).
•
An unused calibration unit may remain connected to the USB port
while the network analyzer is performing measurements. It must
be disconnected during a firmware update.
•
It is safe to connect or disconnect the calibration unit while the
network analyzer is operating. Never connect or disconnect the
unit while data is being transferred between the analyzer and the
unit. Never connect the unit during a firmware update.
