tively. x1 is equivalent to OK ENTER. It confirms the previous entry and deacti-
vates the input field.
The ESC CANCEL and OK ENTER keys are equivalent to the corresponding keys in
the NAVIGATION keypad.

sequence. If an entire numeric value is selected, BACK moves the cursor in front of the
first digit.

The rotary knob increases and decreases numerical values, scrolls within lists, acti-
vates controls and confirms entries. Turning or pressing the rotary knob is equivalent to
the action of the ↑ and ↓ keys or the OK ENTER key in the NAVIGATION keypad.

parameter) between two consecutive values if the rotary knob is turned to increase or

1.1.7 Front Panel Connectors
The test ports and various additional connectors are located on the front panel of the
analyzer.
1.1.7.1
Test Ports
N-connectors (or smaller ruggedized connectors for microwave analyzer types), num-
bered 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).
●
With a single test port, it is possible to generate a stimulus signal and measure the
response signal in reflection.
●
With 2, 3 or 4 test ports, it is possible to perform full two-port, 3-port or 4-port mea-
surements; see
on page 76. Note that for most
R&S
ZVA models, ports 2k-1 and 2k share a common generator; only for
R&S
ZVA24 with 4 ports and 4 generators (order no. 1145.1110.28), R&S
