STEP SIZE opens an input box to select the steps (in units of the current physical
parameter) between two consecutive values if the rotary knob is turned to increase
or decrease numeric values. See
Data Entry in Chapter 3.
STANDBY Key
The STANDBY toggle switch is located in the bottom left corner of the front panel.
The key serves two main purposes:
•
Toggle between standby and ready state
•
Shut down the instrument.
Test Ports
N-connectors, numbered 1 to 4 (for four-port instruments). 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 measurements; see
S-Parameters section in Chapter 3.
Attention!
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.
