About the EMxpert Products
EMxpert product family provides board-level design teams with world-leading fast very-near-eld magnetic
data to help diagnose EMC design issues. EMxpert product line consists of EHX (high-frequency scanner)
and ERX (high-resolution scanner). These instruments capture and display visual images of spectral and
spatial scan results in seconds. This allows the design team to immediately analyze and compare design
iterations. PCB designers can scan any board to identify both constant and time-based emission sources
in the range of 150 kHz to 8 GHz.
EHX consists of a patented scanner and compact adaptor, and a customer-supplied spectrum analyzer
and PC running EMxpert software. Free Keysight IO software application must also be installed on the
customer-supplied PC. The patented scanner consists of 1,218 H-eld (magnetic) probes spaced every
7.5 mm into an electronically switched array, which provides an effective 3.75 mm resolution. The system
operates from 150 kHz to 4 GHz or 150 kHz to 8 GHz; the upgrade from 4 GHz to 8 GHz is enabled with
an optional software license key.
EHX+ is a self-contained very-near-eld scanning device which uses the EHX scanner along with a
built-in spectrum analyzer. Simply connect the EHX+ into the PC with an Ethernet connection, install the
EMxpert software on the customer-supplied PC and begin measurements. The system operates from
150 kHz to 8 GHz.
ERX+ is a self-contained high-resolution very-near-eld scanning device which uses the EHX scanner
mounted on X and Y stepper motors with 0.12 mm incremental measurement steps. It also has a
built-in spectrum analyzer. Simply connect the ERX+ into the PC with an Ethernet connection, install the
EMxpert software on the customer-supplied PC and begin measurements. The system operates from
150 kHz to 8 GHz.
Minimum System Requirements
• CPU 333 MHz or faster
• 128 MB RAM recommended for EHX
• 8 MB Video or more
• Windows XP/Vista/Windows 7/8/8.1 OS
• 10/100 Network Card

Cables and Component Checklist
Components Supplied with the EHX System
1. EHX adaptor
2. EMSCAN’s patented scanner
3. RF SMA to type N coaxial cable: It is referred as the RF cable in this manual. It connects
the scanner to the spectrum analyzer and has a SMA connector for the scanner and a
N connector for the spectrum analyzer 50 ohm input port. It transmits RF output of the
patented scanner to the spectrum analyzer.
4. Micro-D control cable: It connects the adapter to the scanner to enable control of the
EMSCAN’s patented scanner’s switched probes and to power the scanner.
5. USB Cable: It connects the PC (laptop or desktop) to the EHX adaptor. The USB Cable
provided with the system has ferrites on both ends of the cable
6. SMB-BNC Trigger Cable: It connects EHX adaptor to the spectrum analyzer.
7. Surface wave absorber: is only provided with the EMxpert EHX 8 GHz versions to test
above 6 GHz. (part numbers: 3000-1806 and 3000-1808)
8. EMxpert USB Drive includes the EMxpert software installation program and User Manual.
Customer Provided Components
1. SpectrumAnalyzer: It must include the necessary options to work with the EMxpert EHX (see Supported
Spectrum Analyzers). It measures the radio frequency (RF) signal received from the EMSCAN’s
patented scanner, generated by the very-near-eld emissions of an
adjacent activated PCB and it outputs the data to the PC.
2. PC (Laptop / Desktop): It must support a LAN 10/100 connection to the
spectrum analyzer and a USB connection (version 2.0 or higher) to the
adaptor or two USB connections, one for the spectrum analyzer and
one for the adaptor. It runs the EMxpert software and receives data,
which it can display and manipulate immediately or store for future data
presentation.
3. Ethernet or USB cable: It connects PC (laptop or desktop) to the spectrum analyzer.

Quick Installation and Checklist
1. Install latest version of Keysight IO
Click here to open the website to download the latest version. On the website click on the Download
button and follow the steps.
2. Install the EMxpert software application by double clicking on the Setup application icon. The
application must always be installed on the C: drive.
3. Connect PC, scanner, adapter and spectrum analyzer as per the diagram below. If you are using
Ethernet between the PC and the spectrum analyzer, use a crossover Ethernet cable.
If the spectrum analyzer has multiple trigger ports, always connect to Trigger 1 IN.
4. If you are using an USB cable to connect the PC to the spectrum analyzer, go to Step 5.
If you are using an Ethernet crossover cable rst set up your IP address as follows:
Set your spectrum analyzer to the static IP address 172.16.1.148/255.255.0.0; you will probably
have to restart your analyzer.
Set your PC with static IP address 172.16.1.99/255.255.0.0
Best is to set it up in Alternate Conguration in the Local Area Connection Properties /
Internet Protocol Version 4 (TCP/IPv4) / Properties path [in Windows 7 or equivalent path
for other Windows OS]
If you want to use another pair of IP addresses (PC + Spectrum Analyzer) you need to discontinue
the heartbeat function that is today only able to ping 172.16.1.148. Please make the following
change to ‘EMxpert.ini’ in the directory where EMxpert.exe is: C:\Program Files (x86)\EMSCAN
Corporation\EMxpert 5.
Open this le by using notepad; there is the following section at the end:

5. Install the EMxpert USB driver
Go to Control Panel / Hardware and Sound / Devices and Printers / Device Manager [in
Windows 7 or equivalent path for other Windows OS]
Expand “USB Custom Driver” and look for EMxpert USB Driver (C) 2014
If it says 2010 or if there is a yellow triangle, right click and select Update driver and then
browse to the “EMSCAN EMxpert USB Driver” folder in the install folder on the CD, hard disk or
key.
Click on the “EMSCAN EMxpert USB Driver” folder and press OK. Proceed with the installation
steps.
Note that you may have to repeat this procedure if you connect the USB cable between the
adapter and the PC to another USB port at another occasion.
Note as well that not all USB ports are equal; some are less than others and may not work with
the EMxpert adapter. Try various ports until you nd one working properly.
The EMxpert driver is a third-party Microsoft approved driver. If the installation fails you must
disable the third-party driver enforcement of Windows 8 and 8.1 as follows:
Windows 8.0
On the side START bar, click on “Settings”
Click on “Change PC settings”
In PC Settings, click on “General”
Scroll down to “Advanced startup”
Click on “Restart now”
In “Choose an option”, click on “Troubleshoot”
In “Troubleshoot”, click on “Advanced options”
In “Advanced options”, click on “Startup Settings”

6. Open Keysight IO
Look at the bottom right of the Keysight IO window and see if it says PRIMARY VISA
If it does not, go to Control Panel / Programs / Select Keysight IO / Change / Modify / Select
PRIMARY [in Windows 7 or equivalent path for other Windows OS]
When using a FSH 4 or FHS 8 connected via USB to the PC, go to the install folder on the CD, hard
disk or key, open the folder USBDriverFSH8 and run the FSH4_V2_11.exe in order for the Keysight
IO library to recognize the FSH.
Keysight IO is good at auto-discovering and conguring. If it is connected properly you will see in
the bottom section Messages the following two lines:
Instruments are already discovered and congured
User interface session started
If there is a connection issue, mostly with LAN, select Manual Conguration and then LAN
Instrument
In Set LAN Address / Hostname or IP Address
Enter the IP address 172.16.1.148
In Verify Connection
Click on Test this VISA Address
Then click on Accept
If there is still no connection, disable your PC rewall or set it up to allow trafc to/from
172.16.1.148 and repeat the steps above.
If you are using a Keysight X series spectrum analyzer, please refer to Technical Bulletin #9
for additional help in connecting the analyzer.
7. Close Keysight IO
If you are using an Keysight X series spectrum analyzer, please
refer to Technical Bulletin #9 for specic settings before closing
Keysight IO.
Once connected, set the analyzer as a favorite. Click on the grey star and it will turn yellow.
8. Double click on the EMxpert5 icon
Look at the bottom left of the EMxpert application and wait until it shows “Connected to the
Scanner and Spectrum Analyzer”.
Get ready to scan!
If you have any issue, verify that you are using a compatible spectrum analyzer with the right hardware,
