1. Introduction and software description
Thank you for purchasing the AR2300/AR5001D/AR6000 receiver with the optional IQ5001 I/Q board and AR-IQ-III
software.
To obtain the best possible results from your receiver, we strongly recommend that you read this manual and familiarize
yourself with the receiver. Every effort has been made to make this manual correct and up to date. Due to continuous
developments of the receivers and this software, we acknowledge that there might be some changes, errors or
omissions.
The AR-IQ-III software allows direct control of the receiver through a graphical interface. The I/Q digital output of the
IQ5001 board represents the actual signal used after digital processing in the receiver. The digital I/Q output interface
streams I/Q data to the PC through USB2.0 isochronous mode, at 72Mbit/sec with a sampling rate of
1.125Msample/sec. All commands are sent to the receiver through the receiver's remote control USB port.
Compared to a regular AF, which only allows recording one frequency at a time, I/Q allows you to store and playback a
full 0.9MHz bandwidth with no loss of quality!
This 0.9MHz bandwidth can be anywhere within the receiving range of the receiver.
Off-line, you can listen and decode within the recorded 0.9MHz range, tuning any frequency as you would in real time.
You can even loop a particular time frame to listen repeatedly to a signal received in difficult conditions, or search for
and analyze hard to catch signals bursts.
It is also possible to move the I/Q data to another PC and to listen/decode it off line, provided the USB license dongle is
inserted into that PC.
Please note that there is no inter-compatibility of wav files recorded with AR-IQ I, AR-IQ II and AR-IQ III, as they all use
different headers.
2. PC requirements
Suggested PC system:
Supported OS: Win 7/8.1/10
Intel I7 CPU
16 GHz RAM
HDMI resolution monitor
Large size HDD for record/playback operations
Three available USB 2.0 ports are required (one for the I/Q stream, one for receiver control, one for the license dongle)
If you notice "audio stuttering" due to insufficient PC resources, it is possible to adjust the software's "Buffer
Reads/Interval" to match your PC's specifications, as described in chapter 9 "ADVANCED PARAMETERS".
