Of analyzer of HP8591C cable television and norms change synchronism, the exclusive cable television analyzer inside the industry
Analyzer of 8591C cable television (1MHz ～ 1.8GHz) it is the solution that the cable the cable television RF with the first portable stand-alone box, automatic, jam-free economy and video measure. The characteristic of this analyzer is agile hardware and software structure, accordingly, it upgrades easily, can protect your investment when introducing new test to ask.
　　
You are controlling type and standard to undertake cable television checks a need the function that cable television analyzer has by the whole world, include tests of all FCC function test and verify:
Video of RF/ of ·85721A cable television measures special card, can simplify channel and system are wired
TV is measured
·75Ω inputs impedance to make the impedance of analyzer and cable television matchs
Improvement of the outfit inside · carries a confusion of voices to be able to change preamplifier than metrical interior
The frequency of · nicety is fiducial, so that measure carrier frequency accurately
· fast time domain scans, go in order to show separate TV scans
· undertakes according to the TV scanning linage of the choice TV sparks
·RS-232 and collateral interface, use at PC and printer job respectively
·85702A 128K RAM gets stuck, store test data is used
The yellow with strong · is soft carriage box
All sorts of options still can increase the test capacity of analyzer. They include 75Ω to dog generator, narrow resolution bandwidth and jam-free RF and video are measured.

Jam-free measure
Options 107 added for 8591C and analyzer of 8590E series spectrum to undertake jam-free RF and video measure place must hardware. Jam-free the test makes you can be in the many tests that do not affect circumstance of user programme controll to fall to undertake needing to multichannel channel locally. Video measures ability to make you can undertake needs FCC color checks. Options 107 still can observe TV image is mixed at the same time listen to program sound. NTSC of this hardware demodulation makes type TV signal and
PAL and SECAM make type TV signal.

Use all sorts of mediumly measurement at RF and video test
85721A measures special card (include HP 8591C) design technically for analyzer, it is can convenient, jam-free the ground makes type signal undertake function examines to NTSC, PAL or SECAM measure. This software added function of special cable television test mixes all sorts of measurement, these tests need to press a key to be able to undertake only. The measurement of all sorts of functions and test are as follows:
The automatic tuning of · cable television and telecast carrier frequency
The carrier wave n of · image and audio and frequency
Power of · number carrier wave
· system channel is checked
· modulation deepness
· TV audio and deviate of FM broadcast carrier frequency
· carries a confusion of voices to compare (C/N)
The frequency inside · channel is answered
· hum / low frequency interference
· system frequency is answered
The travel of TV of · base band and frame are checked
· TV audio and demodulation of FM broadcast carrier frequency
· is lack fidelity (CSO/OTB)
· across modulation
· inbreaks and check with radio frequency channel
The systematic capacity that monitor makes measure undertake automatically, the test job of analyzer need not operate the help of personnel. It still can make you devise test plan, send test data into the report instantly. options 107 after be being added at analyzer of electrical wiring TV, can undertake the frequency inside comparing of a confusion of voices, channel answers carrying, and lack fidelity jam-free measure and video measures:
· differential gain
· differential is phasic
· chroma one height delay time is inhomogenous quality
The report of save labour and data file
Manage software to be able to produce cable television easily to report with data of 85921B cable television. It moves on IBM compatible PC, can the 8591C from you, CaLan 2010B, 3010, in the PC database that 3010B and 3010R issue test data to produce report and file. This software asks the performance that checks result and you to compare, show the qualification that checks every time / unsuccessful information. Test data also can be outputted to word processing program or electronic form in, so that undertake the analysis of other.
You can be printed in wired system every specify the result that checks every time locally. In printout can list all channel that be measured are reached additional what want information, if check string of date, number that undertakes name, qualification and place use device testing staff. Additional options 032 hind, automatic generation accords with the report of FCC rules form. All RF that FCC asks at present and video test (leakage discharge except) include to be in the report.

185921B measures the systematic pattern data that special card receives to be confined to NTSC format from 85721A.
85721A and 8591C bind a sale, can add on 8590E series analyzer.
