30 Infiniium Z-Series Oscilloscopes User’s Guide
2 Using the Oscilloscope
• Amplitude: 178 mV peak to 1 V peak
• Frequency: 10 MHz ±5 ppm high-quality sine wave or square wave
To use a 10 MHz external reference clock, connect the external clock to the
10 MHz In BNC connector; then, in the Infiniium oscilloscope application's
Horizontal Setup dialog box (Setup > Horizontal...), enable the 10 MHz External
Reference Clock.
You can use the 10 MHz Out BNC connector to send the oscilloscope’s 10 MHz
reference clock output signal to another instrument’s reference clock input.
100 MHz In, 100 MHz Out
The 100 MHz IN SMA connector is used to synchronize the oscilloscope's
horizontal timebase system to a reference clock that you provide. The clock you
provide must meet the following specifications:
• Amplitude: 178 mV peak to 1 V peak
• Frequency: 100 MHz ±5 ppm high-quality sine wave or square wave
To use a 100 MHz external reference clock, connect the external clock to the
100 MHz In SMA connector; then, in the Infiniium oscilloscope application's
Horizontal Setup dialog box (under Setup > Horizontal...), enable the 100 MHz
External Reference Clock.
You can use the 100 MHz Out SMA connector to send the oscilloscope’s 100 MHz
reference clock output signal to another instrument’s reference clock input.
