with 4 ports and 4 generators (order no. 1145.1110.48) and R&S ZVA67 all test
ports are equipped with independent sources.
●
Each test port may be complemented by three pairs of additional connectors used
to test high power devices and extend the dynamic range, see
"Direct Generator and Receiver Access"
Maximum input levels
The maximum input levels at all test ports according to the front panel labeling or the
data sheet must not be exceeded.
In addition, the maximum input voltages of the other input connectors at the front and
rear panel must not be exceeded.
The three LEDs above each test port indicate the connector state:
●
The amber LED is on while the connector is used as a source port.
●
The green LED is on while the connector is used as a bidirectional (source and
receive) port.
●
The blue LED is on while the connector is used as a receive port.
It is recommended to use a torque wrench when screwing RF cables on the test port
connectors. Standard IEEE 287 specifies a torque of (1.5
±
0.2) Nm for N connectors,
(0.9
±
0.1) Nm for the microwave connector types.
1.1.7.2
USB Connectors
Double Universal Serial Bus connector of type A (master USB), used to connect e.g a
keyboard, mouse or other pointing devices, the Calibration Unit (accessory R&S
ZV-
Z5x), a printer or an external storage device (USB stick, CD-ROM drive etc.).
To control external devices (e.g. power meters, generators) via USB connector, a VISA
installation on the network analyzer is required. Use the USB-to-IEC/IEEE Adapter
(option R&S
ZVAB-B44) to control devices equipped with a GPIB interface.
The length of passive connecting USB cables should not exceed 1 m. The maximum
current per USB port is 500 mA. See also
