Hp 141T 18 ghz spectrum analyzer preselector w/ 8555A
Agilent HP 141T 18 GHz Spectrum Analyzer
* 8555A RF Section, 10 MHz to 18 GHz (40 GHz with external RF Tuning waveguid mixer - not included.)
* 8552B IF Section, Resolution Bandwidths from 10 Hz to 300 KHz
* 8445B Preselector, 1.8 to 18 GHz Y1G tuned tracking preselector
The 141T spectrum analyzer mainframe and display features a varible persistence CRT which enables response storage for any measurement. With very narrow bandwidth measurements, extremely slow sweeps are necessary to maintain amplitude calibration. A recording CRT is necssary to save this response for viewing. Any response can be stored for a display ready to be photographed.
The 8555A Spectrum Analyzer covers 10 MHz to 18 GHz with fundamental and harmonic mixing. A single external waveguide mixer (not included) can provide 12.4 to 40 GHz coverage. This broad frequency range coupled with its high sensitivity and resolution bandwidth allow a variety of power measurements, frequency measurements, modulation, and noise analysis on almost every type of design module: the frequency response of amplifiers, mixers, and modulators, response and alignment of filters, isolators, couplers and limiters. With wide scan width and calibrated amplitude the 8555A is ideal for spectrum surveillance and RFI/EMC field strength analysis with a calibrated antenna.
The high resolution 8552B IF section features video filtering, recorder outputs and an internal calibration signal to make the spectrum analyzer easier to use. Video filtering is a low-pass filer which averages noise amplitude response for easier small signal readings. It also makes wide band noise measurements easier.
The 8445B Tracking Preselector is a Y1G tuned filter coupled to the 8555A Spectrum Analyzer in order to be tuned exactly to the analyzer's reception frequency. The preselector suppresses harmonic mixing image and multiple responses form 1.8 to 18 GHz. The result is a wide spurious free amplitude measurement range. Clean, full band sweeps are possible in scans of 2, 4, 6 or 8 GHz depending upon the band selected.
* Paper manuals for all 4 units.
* Band selector lever on RF Section is broken off but can still be easily operated and functions correctly. Otherwise both physical and working condition are very good.
* We do not have the rear interconnect cable for the 8445B but it is available for $115.00 at glkinst.com.
