7 Setting up Measurements
Turn On Hardware
1. Turn on the E6610A. All 8 LEDs will be orange initially, then all of the LEDs will turn
off except for the “SYS PLL” LED, and finally the "AxC Tx" LED will be orange. Note that
the "SYS PLL" LED will be green instead of orange when an external reference signal
is connected.
2. Turn on the power to the remote radio head. The "SFP 1" LED on the E6610A will
blink orange while the CPRI link is initializing. When the CPRI link has been
synchronized, the “SFP 1” LED on the E6610A will turn green. The "STS" LED on the
E6610A will blink green while it is listening for the RRH to send a DHCP request over
the CPRI link. When the RRH has obtained an IP address and the E6610A has
captured the information, the "STS" LED will change to steady green.
Note that in some cases the "STS" LED may not turn steady green even though the
RRH has an IP address, and the LED will eventually turn orange. This occurs when the
E6610A failed to capture the DHCP information for some reason. You can turn the
RRH off and then back on to repeat the DHCP process. If the "STS" LED still does not
go to steady green, you may not be able to obtain the RRH's IP address by querying
the E6610A, and will need to check the list of devices connected to the router to
obtain the IP address.
Connect to the E6610A with the GUI Software
Run the E6610A GUI software by double-clicking on program's desktop icon, or by
going to the Start Menu and navigating to the Keysight > E6610A Remote Radio Head
Tester folder and selecting "E6610A User Interface." The startup screen is shown
below.
