Kenwood 2000X manual If Digital Signal Processing, DSP Detection, Digital Filtering, If Auto Notch

All-Mode, Multiband, Engineered for Excellence

Kenwood’s new TS-2000/2000X/B2000 all-mode multibander may be compact, but it’s equipped with all the features you would expect to find in a top-of-the-line rig.

IF Digital Signal Processing

The TS-2000/2000X/B2000 is serious about digital signal processing. Kenwood’s advanced digital technology converts analog waveforms into digital data in real-time, enabling such digital processing as IF filtering, slope tune, auto notch and AGC. IF-stage DSP on main-band transmit and receive — including V/UHF bands — allows the greatest range of control and unprecedented performance.

DSP Detection

IF-stage DSP means that the TS-2000/2000X/B2000 offers significantly lower distortion and higher quality detection in all modes. (FM: digital

also provides noise reduction capabilities in FSK with 4 steps avail-

able: 250, 500, 1000 and 1500Hz. And thanks to AF-stage DSP, independent control of high-cut and low-cut frequencies (12 steps each) provides slope tune capability in FM as well.

Digital Filtering

There is absolutely no need to purchase optional filters: digital IF filters are available for each mode (FM: digital AF filter), offering performance superior to anything possible with analog circuitry. When operating in SSB/FM/AM modes, this digital filtering enables both high- and low-cut frequency variance. Employing slope tune, you can thus cut out

IF AGC

The digital AGC circuit (main band only) delivers very fast release characteristics, surpassing even the best analog designs. You can select a custom release time (20 steps) for each mode, except FM.
