82 Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz
3 Auto Couple
Remote Command:
See “PhNoise Opt" on page 81.
Example:
FREQ:SYNT:AUTO ON
Optimize £(f) for frequencies < 50 kHz
The LO phase noise is optimized for measuring signals with offsets less than 50 kHz from
the carrier, at the expense of phase noise beyond 50 kHz offset.
Key Path: Auto Couple, PhNoise Opt
Remote Command:
See “PhNoise Opt" on page 81.
Example:
FREQ:SYNT 1
Optimize £(f) for frequencies > 50 kHz
Optimizes phase noise for measuring offsets greater than 50 kHz from the carrier, especially
those from 70 kHz to 300 kHz. Closer offsets are compromised and the throughput of
measurements (especially remote measurements where the center frequency is changing
rapidly), is reduced.
Key Path: Auto Couple, PhNoise Opt
Remote Command:
See “PhNoise Opt" on page 81.
Example:
FREQ:SYNT 2
Optimize LO for Fast Tuning
In this mode, the LO behavior compromises phase noise at all offsets from the carrier below
approximately 2 MHz. This allows rapid measurement throughput when changing the
center frequency or span.
