Test Ports
N-connectors, numbered 1, 2, ... The test ports serve as outputs for the RF stimulus
signal and as inputs for the measured RF signals from the DUT (response signals). Up
to 6 additional test ports can be purchased as options (order no. 1300.1506.03 to
1300.1506.08; see detailed ordering information in the product brochure).
●
With a single test port, it is possible to generate a stimulus signal and measure the
response signal in reflection.
●
With 2 or more test ports, it is possible to perform full two-port or multiport mea-
surements; see
on page 67. Note that pairs of test
ports (1 and 2, 3 and 4 etc.) are supplied by a common generator.
●
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.
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.
1.1.2.2
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
