transmitted wave at the DUT's output port (port no. 2) to the incident wave at the
DUT's input port (port no. 1).
The R&S
ZNLE automatically adjusts its internal source and receiver to the
selected measured quantities: For an S
21
measurement, a stimulus signal
(termed a
1
) is transmitted at the analyzer port no. 1; the transmitted wave (termed
b
2
) is measured at port 2. The stimulus signal from the analyzer port no. 2 is not
needed except for some calibration types.
By default the sweep range is set to the frequency range of the analyzer, which
can be unsuitable for your DUT. The following procedure shows you how to con-
figure a smaller sweep range.
1. Select [Freq] and set the "Start Frequency" to the lowest frequency you want
to measure (e.g. 1.77 GHz). For convenient data entry, double-tap/click the
input field to open the "Numeric Editor".
Tip:
If you use the keypad at the front panel for data entry, type [1][.][7][7] and
terminate the entry with the [G/n] key.
Refer to
on page 61 to learn more about
entering numeric values and characters.
2. In the "Stop Frequency" input field, enter the highest frequency you want to
measure (e.g. 2.5 GHz).
3. Select [Scale] > "Scale Values" and activate the "Auto Scale Trace" function.
The analyzer adjusts the scale of the diagram to fit in the entire S
21
trace,
leaving an appropriate display margin.
