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 external 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 only functional when Option AYZ is ordered.

IF OUTPUTS

321.4MHz The 321.4 MHz IF output signal is present. Conversion 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.

21.4MHz 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.

7.5MHz 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 synchronize 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 signal locks other test equipment to the same frequency reference used by the downconverter. The 10 MHz out signal is at +5 dB.
