Exercise 7
Measuring Signals with the Integrated DVM
The integrated digital voltmeter (DVM) is free when you register
your MDO3000. It monitors voltage values of critical signals
or power rails in your system at a glance without having to
connect a separate meter. The oscilloscope offers 3.5-digit
Voltage Measurements for AC+DC RMS, AC RMS, and
DC and 5.5-digit a Frequency Measurement through the
same probes as the oscilloscope channels. This functionality
is decoupled from the scope trigger circuit allowing for
uninterrupted measurements that are always available, even
when the scope is not running.
This exercise shows how you can measure DC voltage on
a signal over time.
1. Connect a BNC cable to Channel 1 and to the AFG output on
the rear of the oscilloscope.
2. Press Default setup front-panel button.
3. Press the AFG front panel button to bring up the AFG menu.
4. Select the Waveform Settings lower-bezel button to change the
Amplitude and Offset of the sine waveform.
5. Use the key pad (or Multipurpose a and b) and side-bezel
buttons to set the AFG with a Sine wave at 100 kHz frequency,
1Vp-p amplitude, and 500mV offset.
