d) If the measurement result of the second channel has been selected for Trace
B, the graphical display for the measured frequency response of the DUT may
look like the example shown below.
8. Step: Saving this instrument setup
a) Pressing the SAVE key opens the window for saving files.
b) The desired file name can now be entered using the keypad on the front panel.
The keypad on the front panel of the R&S UPV is automatically switched to the
mode for entering alphanumeric characters. Text is entered in the same way as
on cellphones: The characters assigned to a key are called up in sequence by
repeatedly pressing the corresponding key. A different key can be pressed
immediately to enter the next character; a brief pause must, however, be made
when entering characters assigned to the same key.
The file extension is assigned automatically once the file name has been
entered (here .SET); it is advisable to use this automatic assignment function
as it prevents entry errors.
c) If this instrument setup is to be used again at a later date, simply press the
LOAD key to reload the setup in the file window.
3.4.2 Measuring Total Harmonic Distortion (THD+N) of a DUT
This example is also based on the factory settings of the audio analyzer. However,
only the settings in the individual panels which differ from the settings in the previous
example are explained.
1. Step: Loading the factory settings
