| HP - AGILENT 85685A 20 Hz TO 2 GHz RF PRESELECTOR WITH OPTION 8ZE SYSTEM, FOR THE HP 8566B, HP 8567A, AND HP 8568B SERIES ANALYZERS.
I DO NOT know what option 8ZE System is ?? Maybe some kind of Option in a System.
YOU GET EVERYTHING (CABLES AND SPECIAL BUS CABLES) THAT IS NEEDED TO HOOK UP THIS HP 85685A PRESELECTOR TO THE HP 8566B OR HP 8568B SPECTRUM ANALYZER. THE OTHER HP 85685A PRESELECTORS ON EBAY DO NOT HAVE THE SPECIAL BUS CABLES INCLUDED. THIS HP PRESELECTOR WILL NOT WORK OR CANNOT BE TESTED, WITHOUT THE SPECIAL HP BUS ITERCONNECT CABLE WITH THE HSWP IN/OUT ON IT! DO NOT LET THEM FOOL YOU!
WE WILL RE-CALIBRATED THE UNIT BEFORE SHIPPING AND A NIST TRACEABLE CALIBRATION CERTIFICATE WILL BE PROVIDED.
The 85685A RF Preselector makes a multi-purpose test receiver of an 8566B, 8567A, or 8568B Spectrum Analyzer. In addition to an instrument for general-purpose spectrum analysis, you now have a test receiver for specialized applications. The RF preselector, with tracking filters and preamplifiers covering the 20Hz to 2GHz range, improves spectrum analyzer measurement sensitivity while providing overload protection from out-of-band signals. The resulting test receiver system operating in the presence of high-level interference has a measurement range 30 dB greater than that of a spectrum analyzer alone....
This Analyzer works on the principle of “super heterodyne receiver” to convert higher frequencies (normally ranging up to several 10s of GHz) to measurable quantities. The received frequency spectrum is slowly swept through a range of pre selected frequencies, converting the selected frequency to a measurable DC level (usually logarithmic scale), and displaying the same on the CRT of the Agilent 85685A. The CRT displays received signal strength (y axis) against frequency (x axis). Some applications for Agilent 85685A Spectrum Analyzers include Site monitoring Verify that the frequency and signal strength of your transmitter is accurate. Interference before a system is installed you use a Agilent 85685A spectrum analyzer to verify that the frequencies are not occupied or if the presence of a very strong signal will interfere with your new setup. Interference can be created by a number of different situations.
KEY POINTS & FEATURES: *** Reduces overloading from out of band signal. *** Improved system sensitivity. *** Operates with the Agilent 8566B and 8568B spectrum analyzers *** Built in transient limiter. *** Antenna Isolation. *** Co channel interference. *** Adjacent channel power. *** Occupied bandwidth. *** Inter modulation. *** Microwave or satellite antenna alignment, and characterization of components..
