Smart Measurement Solutions

Figure 3: test signal shape - measurement settings

Figure 4: test signal shape - start continuous measurement

Expected Measurement result:

Figure 5: test signal shape - expected result

Waveform:

sinusoidal

peak-peak

~ 1.26 Volts (more accurate measurement follows)

Frequency: ~ 10 MHz (more accurate measurement follows)

If the waveform looks nice, the source amplifiers are working properly.
