RF TRANSMITTER This device is capable of RF transmission on bands or frequencies subject to regulatory oversight. Operators are responsible to ensure use of this device meets local regulatory and legal standards, as they may apply to you and the band of interest. This device is intended for test and measurement use only.

This device is not approved or licensed for transmission over the air using an antenna. This device is capable of RF transmission on bands or frequencies subject to regulatory oversight. It is the exclusive responsibility of customers and end users to ensure use of this device meets local regulatory and legal standards, as they may apply to you and the band of interest.

Overview of Setup

Figure 1: Overall installation and configuration procedure.

Installation and configuration comprises of four parts:

  1. physically setting up the hardware
  2. configuring the host network interfaces,
  3. building and installing the Per Vices libUHD library on the host computer
  4. installing gnuradio

Prerequisite

Plugging in the devices

Hardware set up is reasonably straight forward. As shown in Figure 2, you must connect the ports in the correct order, with the following procedure.

  1. Ensure the Micro SD card is fully inserted inside the Micro SD card reader.
  2. Plug in the power cable at the rear of Cyan.
  3. Connect Ethernet cable from host computer to Management port on front of Cyan.
  4. Connect 40G qSFP+ cables from 40GBASE-R network card installed in host computer to qSFP+ ports on back of Cyan.
  5. Click the rocker switch in the ON position (| symbol) at the back of the unit next to the power supply.
  6. Press the circle button on the front of the Cyan unit and wait for the LED Boot Sequence to complete.
Figure 2: Physical installation of Cyan hardware.

Great! Now that your device is up and running, it’s time to make sure it can connect to the network.

LED Boot Sequence

When Cyan is powered on, the four status LEDs next to the SD card will begin to light up. A normal LED sequence is shown in Figure 4.

Figure 4: Cyan Status LEDs Normal Boot Sequence
Figure Stage Description
a Device is powered on
b FPGA is operating with a stable clock
c FPGA is up and Linux is booting
d HPS is up and Linux has booted
e Server is booting up
f Server has booted up

Great! Now that your device is up and running, it’s time to make sure it can connect to the network.

Power Down Sequence

Power down Cyan gracefully by briefly pressing the power button on the front of cyan or by issuing the command systemctl powerdown to cyan over ssh. Wait approximately 15 seconds until the fans stop. During normal power down sequence the fans will spin at full speed. During normal power down sequence, the second LED may briefly illuminate red. Cyan will then return to standby state with the top LED flashing green.

Cyan can be forced to shutdown immediately by turning off the rocker switch next to the power cable or by holding the power button on the front of Cyan for 7 seconds. Forced shutdowns may cause loss of data and cause stress to some of the RF electronics. Frequent forced shutdown may reduce the lifespan of Cyan.
