FM 1/2 Path Ratio Gain Calibration
Description
This test equalizes the gain between the FM1 and FM2 paths. The gain of the FM2 path is
adjusted using the FM SCALE DAC and the resulting DAC value is stored in the signal
generator’s firmware. This calibration only affects source-independent gains. When
uncalibrated sources feed into the paths, the gains are adjusted using the Modulation
Source Relative Gain Calibration.
Required Test Equipment
• HP/Agilent 3458A Digital Multimeter
• HP/Agilent 53132A Option 050 Universal Counter
• HP/Agilent 33120A 15 MHz Function/Arbitrary Waveform Generator
