1. General Informaon about the T3SP-D4MX
Please read this operaon manual carefully before commissioning the T3SP-
D4MX , to avoid incorrect operaon of the instrument.
The T3SP-D4MX mulplexer unit can be used in applicaons requiring a high
frequency (RF) bandwidth in combinaon with pair-wise phase-matched sig-
nal paths. The mulplexer was developed for test & measurement envi-
ronments as well as for industrial applicaons, by using RF micro-electro-
mechanical-systems switches (MEMS).
A high level of protecon against electromagnec discharge (ESD) is given
by internal protecon diodes.
A main advantage of using MEMS technology is a very long lifeme, which
goes hand in hand with a high number of cycle mes (up to 1 billion). The
device typically is used in mul signal path tesng applicaons (e.g. cable
tesng). It can be programmed either by a stand-alone applicaons or inte-
grated into automated test environments.
Teledyne Test Tools oers TDR systems for measuring impedance proles
and S-parameters. The Teledyne T3SP-10D/15D series is operated by us-
ing the universal instrumentaon soware Seunis that provides control of
the T3SP-D4MX as well as calibraon (open, short, load, thru) and/or de-
embedding of the mulplexer unit.

3. Programming
To have a quick access to the T3SP-D4MX and to be able to perform tests, the
Windows applicaon WinD4MX.exe can be downloaded from the Teledyne
LeCroy website. The program does not need to be installed and does not
require any addional driver components.
Figure 4: Control applicaon WinD4MX.exe
To integrate the device into your own soware environment for remote con-
trol, please read the following secons.
3.1 USB Interface Description
The T3SP-D4MX is controlled via a USB 2.0 interface based on a communica-
on chip from Future Technology Devices Internaonal Limited (FTDI). Win-
dows operang systems usually have the required D2XX-driver for this chip
family pre-installed. If this is exceponally not the case, the corresponding
driver can be downloaded from the FDTI driver download page.
The device is not controlled via a virtual comport protocol, therefore it is
necessary to control it via the cDMXU.dll 32-bit shared library shipped
with the device. In order to simplify the device connecon, some program-
ming examples are listed in the following secon. In case a 64-bit shared
library is required, please contact our Teledyne LeCroy support.
Please use only the supplied USB cable to avoid transmission errors.

3.2 Programming Examples
3.2.1 C/C++-Code
The T3SP-D4MX control library cDMXU.dll is wrien in C++. All funcon
declaraons / signatures can be found in the corresponding header le:
All funcons return a posive value on success and -1 on error. For more
detailed informaon on the individual funcons, please refer to the C source
code below:
int cDMXU_Init(char* id);
int cDMXU_IsInitialized(void);
int cDMXU_SetChannel(int channel);
int cDMXU_GetChannel(void);
int cDMXU_GetSerialNumber(void);
int cDMXU_GetNumberOfChannels(void);
int cDMXU_Release(void);
The following is a simple main program that calls all funcons as an example:
// make sure cDMXU.lib is added to linker dependencies
#include <stdio.h> // include header file
#include "cDMXU.h" // include T3SP-D4MX header
// macro for checking on errors
#define CHK_ERROR(e,m) {if (e<0) {printf(m); return e; } }
int main(void)
{
int no_of_channels = -1; // number of channels of multiplexer
int channel = -1; // channel variable
int serno = -1; // serial number (50001 --> 05.0001)
// initialize library (id string not required yet)
if (cDMXU_Init(NULL) != 0)
CHK_ERROR(-1, "Initialization failed");
