Super wide range

Continuous frequency coverage: 40 kHz to 3.15 GHz in 1 Hz step with 1ppm frequency accuracy. (Frequency accuracy can be optimized to 0.01ppm with an optional GPS receiver.)

Multi-Mode reception

High performance digital signal processing circuitry offers variety of reception modes as well decoding options. Receiving mode includes USB/LSB, CW, AM, SAM, FM, Wide FM and FM stereo. The decoding modes include CTCSS, DCS, DTMF and APCO P-25 by an optional P-25 decoder.

High-Performance analog front-end

The RF frond-end is carefully designed by CAD to optimum performance across the entire frequency range of 40 kHz to 3.15 GHz.

Direct Sampling Architecture (40 kHz - 25 MHz)

The AR-5001D employs 14bit/65Ms/s direct sampling receiver architecture for VLF, LF and HF band. The direct sampling architecture assures high IMD and IP3 characteristics.

Digital Signal Processing

The 45.05MHz IF signal is processed by the independent signal processor for signal demodulation and recovery. No AGC circuitry is used in the analog stage to ensure accurate level reading as well as to offer IF output signal linearity against RF input signal.

FFT Signal Analyzer

The AR-5001D employs FFT(Fast Fourier Transform) signal analyzer that displays 400 kHz to 10 MHz in 100 kHz increment of spectrum to monitor the band activity or detect unidentified signal instantaneously.

Wideband IF output (25 MHz to 3.15 GHz)

A 45.05 MHz of IF analog output signal with 15 MHz bandwidth is provided for external peripherals when using the AR-5001D receiver for front-end. The optional I/Q output board with USB2.0 interface is available to access AR-5001D`s I/Q data for spectrum recording and playback by a PC.


High accuracy reference frequency

The AR-5001D is capable of using GPS pulse signal for an accurate time base for the local oscillator circuit. 0.01ppm frequency accuracy for the 10 MHz internal master oscillator is obtained when synchronized to a GPS signal.

Simultaneous reception and monitoring

Simultaneous reception on HF (below 25 MHz) and VHF-UHF (above 25MHz) frequencies are possible. For frequencies above 25 MHz, absolute dual-channel reception within 5 MHz is possible. Thus, up to three channels can be monitored simultaneously.

Direct digital synthesizer (DDS) local oscillator

Direct digital synthesizer is employed for the 1st local oscillator that ensures fast frequency switching for memory channel scanning and limited band search operation.

SD Audio recorder

AR-5001D is capable of recording demodulated audio signal directly to the built-in SD media recorder. Compact and readily available, SD memory cards are immune to vibrations and produce no mechanical noise, unlike motor-driven media such as tapes or discs.

The AR-5001D can accommodate up to 32GB SDHC card, allowing up to 240 hours of total recording time using PC compatible WAY format. The typical continuous recording time with 1 GB SD card is about 8 hours. The recording time can be extended when sque1ch operation is employed.


Analogue VIDEO demodulation

Composite video output is provided to monitor FM modulated analogue type wireless security camera or frequency search operation for bug transmitter.

Optional APCO P-25 Digital Voice Decoder


APCO P-25 Digital Voice Decoder option is available for the demodulation of project 25 (P25) digital voice communication which are popular in North American for the government and public safety communications.

AF-IQ Output

A 12kHz IF output is provided for a PC sound card based SDR (software defined radio) for signal demodulation by the PC. Typical application includes the reception of DRM (Digital Radio Mondiale) broadcasts on HF frequencies.

Optional Digital I/Q  board  and PC software


When an optional I/Q interface board is installed, up to 1 MHz of digital I/Q output can be recorded to the hard drive of computers operating under Windows environment for later playback and analysis without any loss of quality. This feature allows for unattended logging, signal classification and signal analysis PC control software for Windows XP, VISTA and 7 is supplied with the board.
