How ? :
• Connect the circuit under test to the scope input (observe the max. input rating of the scope!) or connect to
the generator output.
• Start measuring with "trigger off" (6)
• Press 'RUN' (7)
• Choose the desired channel and volts/div setting or press "Auto-set" (2)
• Choose the appropriate time/div setting (8)
To enable triggering :
• Select trigger channel (5)
• Select trigger edge (4)
• Set trigger to 'ON' (6)
• Set trigger level by sliding (3). The trigger mark is displayed on the left hand side of the signal display (1)

How ? :
• Connect the scope input to the circuit under test. (observe the max. input rating of the scope!) Or use the
internal generator output.
• First observe the signal on the scope screen (see previous page).
• Check that the signal is not over the maximum of the screen.
• Start the spectrum analyzer.
• Press 'RUN' (1)
• Select the appropriate frequency range. Make sure your setting will capture any signal change of interest (3).
• If wanted set the appropriate channel and volts/div setting (2)
