Wide Bandwidth Phase Modulation Calibration
(ESG-A and ESG-D only)
Description
This test is used to calibrate the phase modulation circuitry on the synthesizer board. The
phase modulation has two operational modes: normal and wide bandwidth. This
calibration determines the attenuation correction factors for maximum deviation for each
of the phase modulation out-of-band ranges for normal and wide bandwidth modes and
in-band and out-of-band operation. This calibration MUST be performed at the same
frequency as the FM out-of-band calibration (1 GHz). The resulting correction factors are
then stored in the signal generator’s firmware.
Required Test Equipment
• HP/Agilent 3458A Digital Multimeter
• HP/Agilent 8902A Option 010 Measuring Receiver
• HP/Agilent 33120A 15 MHz Function/Arbitrary Waveform Generator
