1. General Informaon about Sequid TDRs

The STDR-65 is used to perform single-ended me-domain reectometry

(TDR) measurements. If the STDT-65 opon is available also me-domain

transmissometry (TDT) measurements can be performed. Dierenal TDR-

Measurements can be performed with the DTDR-65 and DTDR-800.

Step signals with an ultra-wide bandwidth are emied by the instrument.

The signals are applicable to external components via the SMA-connector(s).

The STDT-65 can receive TDT signals via the second oponal SMA-connector;

the DTDR-65 and DTDR-800 generate a second complementary TDR-signal.

Please read this document carefully before commissioning the STDR/T-65

or the DTDR-65/DTDR-800, to avoid incorrect operaon of the instrument.

Keep this manual carefully the enre life-me of the instrument. All devices

listed so far will be referred to as ”device” in the following.

1.1 Intended Application

The device is exclusively intended for usage in conjuncon with the deliv-

ered soware. Upon request soware libraries are available to integrate

the device control into other soware environments. Beware of using the

device for purposes other than intended

1.2 Disclaimer

Warranty or liability claims for personal or property injury are excluded if

they are caused by one or more of the following reasons:

•Usage of the device for other purposes as described in this manual

•Disregarding the instrucons for correct operaon of the device

•Disregarding the safety instrucons listed in this operaon manual

•Opening of the instrument by the customer or user

can be found in chapter 14.

General improvements:

•TTC measurements are checked for plausibility, a user message is raised on

suspicious measurements

•if available, both monitors are used for window auto-arrangement

•shortcut CTRL-ALT-SHIFT-W can be used to arrange windows on a single screen,

even if two monitors are connected

•removed buons from log window, stop logging not needed anymore be-

cause the window is only updated on new logging events

•an overall project comment can be entered and stored now, printed to PDF

reports if non-empty

•de-embedding introduced, can be acvated via tool in main window

•prefered new new project le format is “mas”

•Microso Windows le type associaons are set by installer for sqc and mas

les

•disabled saving to sqz format (zipped), reloading sll supported

•axis sengs, cursors/markers are saved to & loaded from mas les

•calibraon kit data is stored & reloaded from mas les

•renaming mulple samples in list implemented, using wildcards (*) allowed

•new macro can be created based on sengs of exisng sample by right-

clicking the sample

•“change sample sengs” dialog has new entry for selecng tolerance mask

from le, raises le-open dialog

•introduced “Test Standard” info eld, can be set via “Change Sample Set-

ngs” in sample list, will be shown in the PDF-diagrams if set to non-empty

ments to increase performance and improve usability.

3. Commissioning

Before the rst start of operaon you have to install the provided Seunis

soware. Please follow the installaon instrucons given by the soware.

Before starng the soware connect the device and turn it on. The soware

automacally detects the connected instrument.

Remark: In rare cases, the device is not found, which is usually caused by problems

with the USB connecon. In this case please check the USB connecon and drivers.

Latest D2XX-Drivers can be found on the shipped CD, at www.dichip.com or be

requested from [email protected].

3.1 General Remarks

The Seunis measurement soware was designed to make series measure-

ments and therefore the central element of the main window is a spread-

sheet-like table. For a beer understanding, some regularly used terms are

dened below:

Sample Describes the individual objects/devices under

test (DUT)

Sample List Collecon of samples in the spreadsheet table

(D)TTC =

(Dierenal)

Three-Term

Correcon

Error correcon method, removes systemac

device & external cable/connector errors

12TC = Twelve

Term Correcon

Error correcon method for full 2-port

S-parameter measurements. Only used if full

2-port measurement mode is available

Measurement

Modes

The soware is capable of measuring various

parameters (impedance, S11, etc.). These

funconalies are called measurement modes
