artisan 8640B - Sub-Harmonics and Non-Harmonic Spurious Test

Model 8640B TM 9-4935-601-14-7&P
PERFORMANCE TESTS
4-17. HARMONICS TEST (Cont'd)
NOTE
On bands 8 - 16 MHz and above, check for harmonics while tuning down in frequency. For
frequencies above 500 MHz, tune analyzer to observe second harmonic.

4-18. SUB-HARMONICS AND NON-HARMONIC SPURIOUS TEST
SPECIFICATION:
Sub-Harmonics and Non-Harmonic Spurious: (excluding frequencies within 15 kHz of carrier whose effects are specified
under Residual AM and FM) >100 dB below carrier.
DESCRIPTION:
A notch filter is used to remove the fundamental. All non-harmonic spurious and sub-harmonics are then amplified and
measured with a spectrum analyzer.
