8、 installed. 3rd intermodulation dynamic range (3rd IMDR)Reciprocal mixing dynamic range (RMDR)Blocking dynamic range (BDR) The TS-890S uses 8.248MHz 1st IF frequency down conversion for its receive signal system in order to continue the adjacent interference signal exclusion legacy refined in the TS

9、-990S. This means you can use narrow bandwidth crystal filters with passband widths of 500Hz or 270Hz (optional YG-82CN-1) as roofing filters to achieve strong exclusion of unnecessary adjacent signals. The 1st mixer is the H-mode mixer also carried by the TS-990S. Conversion characteristics have be

10、en improved with fine-tuning of input/output matching as well the device used. The configuration of the band scope receiver has changed from the superheterodyne system used in the TS-990S to 1st IF sampling using an A/D converter (14bit/39MHz), and FPGA digital down conversion. This means a change i

14、apes: Medium/ Soft/Sharp. Switching is also possible for post-demodulation voice- audio between 3 kinds of AF filter passbands: Medium/Wide/ Narrow. Combinations of these settings can adjust the sharpness of the demodulation signal. Audio peak filter This is a narrow bandwidth peak filter operated d

15、uring receive in CW mode. When intelligibility is low due to noise, it has the effect of floating the target signal and increasing intelligibility. The central frequency is linked to the pitch frequency, and can be given a maximum peak gain of +6dB. Notch filter A notch filter that operates in the I

16、F stage. By eliminating strong interfering signals, it allows weak target signals to stand out. Damping range can be switched between three levels: Narrow/Middle/Wide, enabling operation to match interference conditions. Noise reduction function (NR1/NR2) In addition to conventional NR1/NR2 noise re

17、duction, NR1 comes equipped with noise reduction using spectral-subtraction, which focusses on noise reduction in voice-audio system modes. The optimum noise reduction method is applied for each receive mode. Noise blanker A noise blanker reduces crackling, pulse-type noise. The TS-890S includes two

18、 kinds of noise blankers: NB1, which processes analogue signals, and NB2, which carries out digital processing in the IF stage using DSP. Furthermore, selection of NB2 can be made from two kinds of NB with different operating principles. Either NB1 or NB2 can be used depending on noise conditions, o

19、r both can be used simultaneously. Beat cancel function (BC1/BC2) While a notch filter (IF stage) is effective for a single strong beat, beat cancelling (AF stage) shows results on multiple, comparatively weak beats. BC1 is effective on weak beats and continuous beats, while BC2 is effective on inte

20、rmittent beats like CW signals. AGC Quick recovery A function to recover from suppression that happens when pulse noise is included in a receive signal.

21、14.1 MHz Interference signal exclusion is not determined by roofing filters and signal system devices alone. The TS-890S has taken the VCO division of the TS-990S and developed it further, combining a VCO device with high C/N in the gigahertz band and a reference oscillation circuit with superior ad

22、jacent C/N to deliver C/N characteristics unattainable in conventional units. Passband frequency range expansion through LOW-CUT/HI-CUT, WIDTH/SHIFT. Interfering signal removal and desired audio-quality adjustment, as well as more convenient operation in digital mode. Operation with LOW-CUT / HI-CUT

23、 in SSB/AM/FM mode, WIDTH/ SHIFT in CW mode, and WIDTH function in FSK/PSK mode. Change to WIDTH/SHIFT operation as in CW mode also possible in SSB/SSB- DATA mode. Selection of roofing filter (270Hz*/500Hz/2.7kHz/6kHz/1 5kHz) can be automatic to match IF filter passband width or manual to selectable

24、 frequencies. (*270Hz when option mounted) A variety of functions are realised through 32-bit floating-point DSP technology inherited from the TS-990S, including modulation/demodulation in all modes, IF filter, IF-AGC, and removal of interfering signals. Popular for its non-tiring and great-quality

25、audio, the IF-AGC has undergone a facelift with a combination of roofing filters and IF filters, and has been designed to enable optimal control under various noise circumstances. 6 Evolved power to perform with diverse displays and auto-scroll.

26、peed. Display / Transmitter The unit carries a high definition 7-inch TFT color display. In addition to a diverse range of display content, the convenient AUTO SCROLL MODE provides strong support for competition or similar operation. Other strengths include clean and stable 100W* transmitter output,

27、 improved quietness from twin cooling fans, and high-speed operation enabled by an auto antenna tuner. Operational capacity reinforced with displays and various features A band scope providing ease-of-ease Improved reference level operability ease-of-use The seven-inch TFT color LCD is the same size

28、 as that used in the TS-990S. In addition to basic information including frequency, mode, and S-meter, the band scope and audio scope are also displayed. The TS-890S also displays further improvements in visibility and operability in tough usage scenarios such as competitions. AUTO SCROLL MODE In ad

29、dition to conventional CENTER MODE and FIXED MODE, the unit comes equipped with an AUTO SCROLL MODE. While in FIXED MODE, if the receive frequency goes over the scope edge, then auto- scroll will engage for half a screen width. Furthermore, with the EXPAND function turned on, the screen to be displa

CENTER MODE When changing the receive frequency in CENTER MODE, there are many units that display a bright line that flows obliquely over the waterfall, but with the TS-890S, the bright line remains straight and enables tuning operation*. Switching to the fol

32、low display is also possible via the menu. *: During straight display, the waterfall bright line temporarily stops and undergoes parallel displacement. Image becomes slightly coarse when expanded. The TS-890S has improved operability of the reference level focusing on the visibility of the waterfall

33、. Through optimisation of each span, readjustment is mostly unnecessary when switching between them.* Settings are enabled for each band, and readjustment is also unnecessary for the PRE AMP ON and PRE AMP OFF bands. *: Spectrum scope waveform height changes during span switching. FIXED MODE FIXED M

34、ODE allows you to switch between three kinds of display ranges with a single touch of the panel screen. The initial value is preset based on the band plan, but this can be easily adjusted to a desired scope. With the spectrum scope and waterfall screen display, the analogue meter is simultaneously d
