Table 4-1. Operational Verification Descriptions
1. Amplitude (0.55 volts (±0.05 volts/50 Ω , 1 volt ± 0.2 volt/1k Ω ).
a. Equipment required:
BNC-to-BNC Cable
500 and 1 K Ω loads
3406A AC Voltmeter
2. Harmonic Distortion (-25 dB below 10 MHz output signal).
a. Equipment required:
141T Display Section
8553B Spectrum Analyzer - RF Section
8552B Spectrum Analyzer - IF Section
BNC-to-BNC Cable
3. Spurious Signals - Signals unrelated to the 10 MHz output signal (-100 dB below the 10 MHz
output signal).
NOTE
Due to the complexity of measuring signal 100 dB
below a reference, this procedure will verify that no
spurious signals exist greater than 65 dB below the
normal 10 MHz output signal.

4-11. In the following tests, the power supply voltages to the oscillator are not shown. They are
assumed to be:
Oscillator
Circuits ........................................ +12V dc
Oven Circuits ............................................... +20V dc
4-12. Any supply voltages within the specified limits listed in
Table
1-1 may be used and will not affect
the operational verification. The voltages are only reference points and are used throughout this
manual.
