Agilent
N8201A Performance Downconverter
Synthetic Instrument Module
3 Hz to 26.5 GHz
Data Sheet
www.DataSheet4U.com
The Agilent Technologies N8201A performance downconverter synthetic
instrument module down converts a microwave signal to an IF signal providing
IF output frequencies of 7.5, 21.4, and 321.4 MHz to offer three different signal
bandwidth capabilities. External mixing can be utilized to downconvert
microwave signals up to 110 GHz. The N8201A is based upon the industry’s
most accurate spectrum analyzer, the PSA Series spectrum analyzer.
Agilent's synthetic instrument family offers the highest-performing RF/MW
LAN-based modular instrumentation and the smallest footprint for automated
test systems (ATSs); providing the maximum flexibility and minimizing the cost
of an ATS over its lifetime.
• LXI Class-A compliant
• Microwave performance similar to the E4440A PSA Series high-performance
spectrum analyzer
• Coherent LO input/output port allowing a common LO signal to drive
multiple downconverters
• 200 MHz wide modulation bandwidth with pre-selector off

1. Nominal changes of phase noise sidebands with other center frequencies are shown by some examples in the graphs that follow. To predict the phase noise for
other center frequencies, note that phase noise at offsets above approximately 1 kHz increases nominally as 20 x log N, where N is the harmonic mixer mode.
For offsets below 1 kHz, and center frequencies above 1 GHz, the phase noise increases nominally as 20 log CF, where CF is the center frequency in GHz.
2. Noise sidebands for offsets of 30 kHz and below are shown for phase noise optimization set to optimize £(f) for f < 50 kHz; for offsets of 100 kHz and above,
the optimization is set for f > 50 kHz.
