1 System Overview
+
The CI-250 LSProbe system consists of a laser-powered
high-speed E-Field Probe, an integrated CI-250 Computer
Interface, a single-board computer, an integrated touch-
screen display, a power cord and a USB ýash drive.
+
The CI-250 Computer Interface is delivered with a pre-
installed LUMILOOP TCP Server, LUMILOOP GUI, fac-
tory calibration data, and optionally, accredited calibration
data.
The USB ýash drive contains the LUMILOOP Windows In-
staller, including the LUMILOOP GUI for remote <+=Device
access, as well as a copy of the calibration data.
Third-party EMC software communicates with CI-250
LSProbes using SCPI commands exchanged over TCP/IP.
2 Making Optical Connections
Note: Every LSProbe is delivered with plugged optical
connectors and ready to use.
Sacriücial optical cable kits are supplied with each LSProbe
E-Field Probe. Always use the E2000 connectors shown
above for breaking and making the optical connection. The
E2000 connectors of the sacriücial cable kit include au-
tomatic shutters preventing contamination and avoiding
optical über burn-in. Nevertheless, all optical connectors
must be kept in a perfectly clean condition at all times.
In case of a über connector burn-in only a pair of sacriücial
cables need to be replaced, allowing for rapid and cost-
eûective fault recovery without requiring external service.
For detailed instructions, consult the LSProbe User's Man-
ual, Section 5.1.1.
3 System Startup
1. Connect the included mains power cord to the CI-
+
250 .
2. Switch on the CI-250
switch to <green=and observe the green <Power= LED
above the front USB port starting to ýash. The LU-
MILOOP TCP Server and the LUMILOOP <+=Device
GUI will start automatically. The green <Power= LED
will light up constantly to show correct operation.
3. Additional LUMILOOP LSProbe and/or LSPM de-
vices can be connected to the CI-250
4 LUMILOOP <+=Device GUI
The LUMILOOP <+=Device GUI is started automatically af-
ter system boot, communicating with the LUMILOOP TCP
Server running in the background.
1. Tap on the labeled <Laser OFF= button to activate the
supply laser and turn on the E-Field Probe. The Com-
+
puter Interface's orange <Laser on= indicator LED will
show the activity of the supply laser.
Warning: When the orange LED is ýashing, Auto-
matic Power Reduction (APR) is disabled. Interrupt-
ing optical connections is dangerous!
Proper operation is indicated in the GUI by display-
ing a green <Laser Status=, continuously on <Power=,
<Laser on= and <Data Link= LEDs as shown below.
2. The GUI displays the E-üeld strength values for the
x-, y-, z- axes, the isotropic üeld strength, maximum
and minimum calibrated üeld strength for the set
mode.
