artisan 8640B - Peak Incidental Phase Modulation Test Setup

Model 8640B TM 9-4935-601-14-7&P
PERFORMANCE TESTS
4-35. PEAK INCIDENTAL PHASE MODLULATION TEST
SPECIFICATION:
Peak Incidental PM (at 30% AM):
Less than 0.15 radians, 0.5 to 128 MHz.
Less than 0.3 radians, 128 to 512 MHz.
DESCRIPTION:
A vector voltmeter is used to compare the phase of the signal into the generator's modulation amplifier with the phase of
the same signal (modulated at a 0.1 Hz rate) at the RF OUTPUT port. The signal is supplied by the generator's own
oscillator and divider circuits and has low incidental PM.
