FM Out-of-Band Calibration (ESG-A and ESG-D only)
Description
This test adjusts the FM out-of-band deviation to match the in-band FM deviation. It also
determines the attenuation values of the out-of-band attenuators and sets the values of
some other FM constants. The loop bandwidth of the synthesizer phase-locked loop is
approximately 5 kHz. This calibration is used to set the FM deviation at rates above the
loop bandwidth (out-of-band) so they will equal the deviation rates within the loop
bandwidths (in-band).
Required Test Equipment
• HP/Agilent 3458A Digital Multimeter
• HP/Agilent 8902A Option 010 Measuring Receiver
• HP/Agilent 33120A 15 MHz Function/Arbitrary Waveform Generator
