1.2kHz "Optimum" roofing filter

The IC-7850 utilizes a newly developed 1.2kHz roofing filter, greatly improving the in-band adjacent signal performance. This enhancement enables the up-conversion design of the IC-7850 to have excellent filter performance while providing a dynamic range that outperforms the competition in the 10kHz or less separation tests.

New local oscillator design

Breaking tradition, Icom employs a Direct Digital Synthesizer (DDS) along with a Phase Locked Oscillator for the IC-7850’s Local Oscillator (LO). The LO's C/N ratio excels beyond our competitors, and the noise components generated in both receive and transmit signals are reduced virtually below detection.

Improved phase noise

With the latest design of the LO, the IC-7850 will become the new benchmark for Phase Noise with –150dBc/Hz at 10kHz offset and –140dBc/Hz even at 1kHz offset. (Previous mark of Phase Noise excellence was –138dBc/Hz at 10kHz offset and –110dBc/Hz at 1kHz offset.)

Improved spectrum scope

By using the dedicated DSP for the Fast Fourier Transform (FFT) spectrum scope, the IC-7850 provides faster sweep speeds and better accuracy than other brand models, even the IC-7800.

Span Width 5kHz–1000kHz
Resolution *1 1 dot *3
Sweep Speed 29.3 samples/Sec *4
Input Dynamic Range 116dB *5
Max. Sensitivity *2 –39dBµ *5

*1 Number of dots shown at 60dB level, when receiving a signal
*2 Recognized level at the Spectrum Waterfall
*3 SPAN=More than 20kHz, SPEED=Slow
*4 SPAN=Less than 20kHz, SPEED=Fast
*5 SPAN=5kHz, SPEED=Slow

Dual scope function

Another scope enhancement in the IC-7850 is the ability to simultaneously "see" activity in both bands. This is useful when searching for multipliers on the Sub band while maintaining your operating frequency on the Main band.

Enhanced mouse operation for the spectrum scope

Connect a mouse to the USB port to change the operating frequency, tune the frequency, switch Fixed and Center mode, adjust the sweep speed and more. Also, simply click on a signal on the scope and the frequency is automatically selected as your operating frequency.
