CT712 LANforge RF Noise Generator and RADAR Simulator

The CT712 RF Noise generator and RADAR Simulator is used for WiFi testing. The CT712 uses the HackRF software defined radio to generate sub microsecond precision bursts of non-modulated RF Noise.

The pulse width, pulse count, pulse repeating interval, pulse repetition frequency, frequency modulation for chirps, chirp width, and single or continuous bursts are configurable. This can simulate many RADAR bursts and so be used for DFS testing.

FCC0-6 are fullysupported. FCC5 chirps between 5 - 14 MHz have high probability of detection. For FCC5 chirps 14 - 20 MHz chirps generated, some AP's have difficultly detecting at -62 dBm (EIRP < 200 milliwatt) or -64 dBm (EIRP >= 200 milliwatt) which may be due to CT712 implentation. Higher power thresholds will provide detection. FCC5 supports low, center, and high UUT channel with 90% overlap for low and high. FCC6 is supported to have 100 hops between 400 - 500 microseconds so does not meet the 333 microseconds window.

ETSI0-6 are fully supported supported. The configurable pulse width can be set to as low as .5 microseconds. Setting higher sample rates can have pulse width granularity to .1 microseconds.

Waveforms Japan W53 1-8 are fully supported. Japan W53 fixed pulses supports 2.7 microseconds. Japan W53 chrip supports .5 microseconds pulse width and configurable chirp width.

Waveforms Japan W56 1-6 are fully supported.

Waveforms Korea1-4 are fully supported.

Waveforms China1-6 are fully supported.

In addition, this unit can create constant modulated and non-modulated RF Noise to enable testing CCA features in WiFi equipment for Signal Detect (SD) at -72 dBm transmission and Energy Detect (ED) at 20 dBm greater than Signal Detect. (you will probably need an RF attenuator as well for CCA testing). It is a test tool, and should be used in an RF isolation chamber or other area where you will not interfere with legitimate RF Equipment or RADAR devices.

The CT712 can support many RADAR types. It is an affordable tool for basic RADAR signal testing, but it is NOT a replacement for a fully compliant RADAR emulator.

The CT712 is controlled by the LANforge software suite, which includes a GUI management tool as well as CLI interface for automated scripting. There is also a DFS WebGUI for testing automation. The LANforge Linux system is required. Contact your sales representative if you have any questions. The LANforge Linux system needs to have fedora 30 or greater.

The CT712 has no moving parts and will fit into a small travel bag or briefcase for easy portability.

Software Features

RADAR signal emulator and non-moduled RF Noise Generator.
In addition to emulating bursty RF noise and RADAR patterns, this tool has proven useful for testing part of CCA logic when paired with a variable attenuator and configured for constant noise transmission.

The RF Noise Generator has the following support for generating RADAR signals:

• It can do a minimum pulse width of .5 us. ETSI1-3 and some other RADAR signals define the minimum at 0.5us, so this RADAR emulator can test that lower bound of the pulse width. Depending on transmit sample rate pulse width of .1 can be achieved.
• FCC-5 and some other RADAR signals define a modulated chirp and ability to change the chirp bandwidth. The LANforge RADAR emulator does currently support modulated chirps. It has ability to change modulation from 5 MHz to 20 MHz

It currently supports a series of bursts with different PRF.

• It supports FCC0, FCC1, FCC2, FCC3, FCC4, FCC5 and FCC6. For FCC5 some AP's having issues detecting chirps between 14-20 MHz. FCC6 can complete 100 hop sequency in under 500 us.
• It supports ETSI1, ETSI2, ETSI3, ETSI4, ETSI5, and ETSI6.
• It supports Japan W53-1, Japan W53-2, Japan W53-3, Japan W53-4, Japan W53-5, Japan W53-6, Japan W53-7, and Japan W53-8.
• It supports Japan W56-1, Japan W56-2, Japan W56-3, Japan W56-4, Japan W56-5, and Japan W56-6.
• It supports Korea-1, Korea-2, Korea-3, and Korea-4.
• It supports China-0, China-1, China-2, China-3, China-4, China-5, and China-6.

The configurables include:

RADAR Type

This specifies the RADAR type or OFDM for modulated and unmodulated RF signal.

Pulse Width

This specifies the duration (in microseconds) for the transmitter to be enabled. The user may type in a specific value, and the LANforge-GUI has pre-set values in pull-down menus for common FCC, ETSI, Japan W53, Japan W56, Korea, and China. The current hardware supports a minimum pulse width size of .5 us.

Pulse Count

This specifies how many pulses to generate, For FCC5 and W56 this is the number of bursts in 12 seconds. For W53, this is the continuous-pairs-of-pulses. The user may type in a specific value, and the LANforge-GUI has pre-set values in pull-down menus for common FCC, ETSI, Japan W53, Japan W56, Korea, and China RADAR patterns.

Pulse Interval

This specifies the time (in microseconds) between starting to generate a pulse. This is also known as "Pulse Repetition Interval (PRI)". The user may type in a specific value, and the LANforge-GUI has pre-set values in pull-down menus for common FCC, ETSI, Japan W53, Japan W56, Korea, and China RADAR patterns.

Pulse Repetition Frequency 1,2,3

This specifies how many pulses to generate before pausing for "sweep time". If you want to pulse continuously, set Sweep Time to zero. This is also known as "Pulses per Burst (PPB)". The user may type in a specific value, and the LANforge-GUI has pre-set values in pull-down menus for common FCC and ETSI RADAR patterns.

Sweep Time

This specifies how long to pause (in microseconds) between pulse bursts. This emulates RADAR sweep time. Set this value to zero for continuous pulsing.

Frequency

Select the frequency on which to generate the RF signal.

One Burst

Generate a single pulse burst and then stop. This allows manual testing with pauses to verify the device under test detected the RADAR properly.

OFDM Modulation

OFDM Modulation to allow for BPSK and QPSK modulation. The header and payload need to be at the same modulation.

Sample Rate

Sample Rate is the transmitted in MHz.

Hardware Specification

1. RADAR signal emulator, non-modulated, and modulated RF Noise Generator.
2. Includes HackRF Software Defined Radio and USB adapter.
