Toggle between standby and ready state, if the instrument is AC-supplied and
appropriately configured.
1.1.8 Test
Ports
N-connectors labelled PORT 1 and PORT 2/ RF INPUT. The test ports serve as
outputs for the RF stimulus signal and as inputs for the measured RF signals from the
DUT (response signals).
C
With a single test port, it is possible to generate a stimulus signal and measure the
response signal in reflection.
C
With 2 test ports, it is possible to perform full two-port measurements; see S-
Parameters section in Chapter 3.
C
The two network analyzer ports are equivalent. If the Spectrum Analysis option
(R&S ZVL-K1) is active, test port PORT 2 serves as an AC-coupled input for the
analyzed RF signal; PORT 1 is not used.
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.
1.1.9 USB
Connectors
Two single Universal Serial Bus connectors of type A (master USB), used to connect a
keyboard (recommended: PSL–Z2, order number 1157.6870.03), mouse
(recommended: PSL–Z10, order number 1157.7060.03) 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.).
Using an adapter cable (R&S NRP–Z4), a power sensor can be connected, as an
alternative to the power sensor connector on the rear panel that is only available with
option Additional Interfaces, R&S FSL–B5.
