AR-IQ-III software

AR-IQ-III software – AR5700D receiver

The AR-IQ-III software allows receiver control, I/Q recording and playback for your AR5700D receiver.

The receiver’s I/Q digital output 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.

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 the “ADVANCED PARAMETERS” chapter.

 

Connecting the receiver to the PC

Connect the two supplied USB cables as follows:

  1. For receiver control: Receiver’s USB socket (labelled with USB logo), to PC.
  2. For I/Q data stream: Receiver’s USB socket (labelled “I/Q OUT”), to PC.
  •    Make sure to connect the I/Q stream USB cable to a direct USB socket connection on your PC. Avoid using a USB hub.
  •    Some type of USB 3 ports can be incompatible due to the particular chipset they use. If that occurs, use a USB 2.0 port instead.

License dongle

Insert the supplied USB dongle in an available USB port of your PC. Windows will automatically install a driver, recognize it as a common USB flash drive and assign a drive letter such as “D:”, “E:” etc….

WARNING:

Our USB dongles are guaranteed without virus infection, nevertheless some virus detection software may incorrectly detect some of its files as a virus (or Trojan). This is called a false-positive alarm and does not mean that files are indeed infected.

Whenever your virus detection software informs you about a possible threat, it usually gives you a choice of options about what to do next. Be sure to flag those files as SAFE files, otherwise the dongle’s files might be rendered unusable or even deleted by the virus detection software, and the AR-IQ-III software will not run.

It is your responsibility to make sure that your virus detection software does not accidentally render the USB license dongle and I/Q software unusable. The license information data inside the USB dongle is unique and cannot be copied or backed-up. If you damage the USB license dongle, a new one needs to be purchased.

The license information data inside the USB dongle is unique and cannot be backed-up, copied or moved. If you lose or damage the USB dongle, a new USB dongle needs to be purchased.

Do not record I/Q data to this dongle and do not use the dongle to store any data.

Formatting the USB dongle, overwriting or deleting its content will destroy the licensing system, and another USB dongle would have to be purchased.

Installing the drivers

There are 2 drivers to install: One for the I/Q output and one for the receiver control.

(All following instructions and screenshots are based on the Windows 10 operating system)

  1.    Switch the receiver ON.

Depending on your Windows version and whether or not you have already installed the drivers on your PC before, it is possible that Windows automatically installs the drivers for you.

  1.    To check the driver status, open WINDOWS DEVICE MANAGER (press simultaneously the Windows key and the X key, then select “Device Manager”)
