Agilent N8201A Performance Downconverter Synthetic Instrument Module, 3 Hz to 26.5 GHz 85
EXT MIXER
1st LO Out The 1st LO output (3-7 GHz at +15 dBm max) allows connections for external
mixing. The 1st LO output routes the internal first LO signal to an external mixer, which uses
the higher harmonics to mix with the high frequency signals. The external mixer’s IF output
connects to the downconverter’s IF input port.
Pre-Sel Out The Preselected e xternal mixer tune output offers tuning voltage for a
preselected mixer.
IF In (Option AYZ) The IF input (321.4 MHz Nominal at -20 dBm, +10 dBm max) allows
connections for external mixing. This port is on ly functional when Option AYZ is ordered.
IF OUTPUTS
321.4 MHz The 321.4 MHz IF output signal is present. C onversion gain is nominally +2 to
+4 dB (with 0 dB input attenuation). Conversion gain varies nominally ±3 dB as a function
of tune frequency. The conversion gain drops at higher frequencies.
21.4 MHz The 21.4 MHz IF output signal is present. Conversion gain is nominally
+10 dB (with 0 dB input attenuation). The conversion gain drops at higher frequencies.
7.5 MHz The 7.5 MHz IF output signal is present. The 7.5 MHz output signal is at
nominally at +13 dBm.
TRIGGERS
These SMB trigger input and output connectors are used to control the waveforms and
create event-based signal simulation. These connectors support LVTTL logic levels.
In allows external triggering of measurements.
Out used to sy nchronize other test equipment with the downconverter.
REFERENCES
1 - 30 MHz In Selects an external reference to phase lock all oscillators in the
instrument. You can select any external reference frequency between 1 and 30 MHz.
10 MHz Out A switched output of the analyzer’s internal 10 MHz reference s ignal locks
other test equipment to the same frequency reference used by the downconverter. The
10 MHz out signal is at +5 dB.
