Figure 4-23 Timebase Aging Rate Test Setup
Procedure
1. Preset all instruments and let them warm up for at least one hour.
2. If the oscilloscope does not have a 50
Ω
input impedance, connect channel 1 through a
50
Ω
feedthrough.
3. On the oscilloscope, adjust the external triggering for a display of the 10 MHz REF
OUTPUT signal from the synthesizer.
a. On Channel 1 of the oscilloscope, set the following:
• Display: On
• Volts/Division: 500 mV
• Input Coupling: dc
• Input Impedance: 50 ohms (or use a 50 ohm feedthrough)
b. On Channel 2 of the oscilloscope, set the following:
• Display: Off
• Input Coupling: dc
• Input Impedance: 50 ohms (or use a 50 ohm feedthrough)
c. On the Timebase of the oscilloscope, set the following:
• Time/Division: 5 ns
d. On the Trigger of the oscilloscope, set the following:
• Trigger Source: CH 2
• Trigger Mode: Normal
• Trigger Level: 0 V
