Moku:Lab's Bode Analyzer can be used to measure the magnitude and phase of a system's transfer function using a swept sine output from 10 mHz to 120 MHz.
- Linear or logarithmic swept sine output
- Probe two systems simultaneously, or one system at two points
- Math channel to add, subtract, multiply or divide response functions as they are acquired
- See magnitude and phase on the interactive Bode plot
- Use cursors and markers to measure exact values on the plots
- Precisely adjust settling and averaging time to suit device under test
- Save a calibration trace to compare systems or remove spurious cable shifts
- Easily save data and upload to the cloud
- Frequency range 10 mHz to 120 MHz
- 50Ω / 1MΩ input impedance
- Variable averaging/settling time (10us - 10s)
- Linear/logarithmic sweep
+ How can I plot the ratio of Input 1 and Input 2?
By default, each channel shows the ratio of the input to the output, In / Out. This is useful for measuring the transfer function of a device under test. The math channel allows you to plot different combinations of Ch 1 and Ch 2. If the output amplitudes of both channels are set to the same value, then viewing the math channel as Ch 1 / Ch 2 will show the ratio In 1 / In 2, since the outputs are the same.
