Figure 8-22 Internal Timebase: Aging Rate Equipment Setup
1. Connect the equipment as shown in Figure 8-22.
2. Preset all instruments and let them warm up for at least one hour.
NOTE If the oscilloscope does not have a 50Ω input impedance, connect channel 1
through a 50Ω feedthrough.
Configure the Oscilloscope
On the oscilloscope, adjust the external triggering for a display of the 10 MHz REF
OUTPUT signal from the synthesizer.
1. Channel 1:
Display: On
Volts/Division: 500 mV
Input Coupling: dc
Input Impedance: 50Ω (or use a 50Ω feedthrough)
2. Channel 2:
Display: Off
Input Coupling: dc
Input Impedance: 50Ω (or use a 50Ω feedthrough)
