All available applications are provided in the "Apps" dialog.
► To open an application, press the [Apps] key.
Some applications are described in different chapters. See:
●
Chapter 8.4, "Reference waveforms", on page 176
●
Chapter 15, "Waveform generator (option R&S MXO5-B6)", on page 386
●
Chapter 12.5, "File browser dialog", on page 283
●
Chapter 13, "Protocol analysis", on page 285
Also the "Demo" is available in the "Apps" dialog. It is only for demonstration purposes
of the functionalities of R&S MXO 5.
11.1 Frequency response analysis (option R&S MXO5-K36)
The frequency response analysis (FRA) option lets you perform low-frequency
response analysis on your oscilloscope. It characterizes the frequency response of a
variety of electronic devices, including passive filters and amplifier circuits. For
switched-mode power supplies, it measures the control loop response (CLR) and
power supply rejection ratio (PSRR).
The FRA option uses the oscilloscope’s built-in waveform generator to create stimulus
signals ranging from 10 Hz to 100 MHz. Measuring the ratio of the stimulus signal and
the output signal of the DUT at each test frequency, the oscilloscope plots gain and
phase logarithmically.
Having both time and frequency domain views allows you to monitor if the injected sig-
nal causes distortion that leads to errors in the measurement.
