Example 2: Gain of the Amplifier in the Metering Circuit
Set the probe menu attenuation coefficient as 10X and that of the switch in the probe as 10X.
Connect the oscilloscope CH1 channel with the circuit signal input end and the CH2 channel to the output end.
Operation Steps
1. Push down the AUTOSET button and the oscilloscope will automatically adjust the waveforms of the two
channels into the proper display state.
2. Push down the MEASURE button to show the MEASURE menu.
3. Press the F1 menu selection button and choose Source.
4. Press the F2 menu selection button and choose CH1.
5. Press the F3 menu selection button and choose CH2.
6. Press the F1 menu selection button again and choose Type.
7. Press the F2 menu selection button and choose Pk-Pk.
8. Press the F3 menu selection button and choose Pk-Pk.
9. Read the peak-to-peak values of Channel 1 and Channel 2 from the displayed menu (see Fig. 106).
10. Calculate the amplifier gain with the following formulas.
Gain = Output Signal / Input signal
Gain (db) = 20×log (gain)

Example 3: Capture the Single Signal
The digital storage oscilloscope takes the lead in providing the convenience capturing of such non-periodic
signals as pulse and burr, etc. If you intent to capture a single signal, you cannot set the trigger level and the
trigger edge unless you have particular priori knowledge of this signal. For example, if the pulse is the logic
signal of a TTL level, the trigger level should be set to 2 volts and the trigger edge be set as the rising edge
trigger. If it is uncertain as to the signal, you can make an observation of it in advance under the automatic or
ordinary mode to determine the trigger level and the trigger edge.
