Measuring Two Signals
TDS2000C and TDS1000C-EDU Series Oscilloscope User Manual
If you are testing a piece of equipment and need to measure the gain of the audio
amplifier, you will need an audio generator that can inject a test signal at the
amplifier input. Connect two oscilloscope channels to the amplifier input and
output as shown next. Measure both signal levels and use the measurements to
calculate the gain.
To activate and display the signals connected to channel 1 and to channel 2, and
select measurements for the two channels, follow these steps:
1. Push the AutoSet button.
2. Push the Measure button to see the Measure Menu.
3. Push the top option button; the Measure 1 Menu appears.
4. Push Source ► CH1.
5. Push Type ► Pk-Pk.
6. Push the Back option button.
