■ mit wenigen Handgriffen zu installieren ist.■ can be installed in just a few steps .
■ den vollen Videosignalablauf präzise und preiswert erfaßt und auswertet.■ the complete video signal sequence is recorded and evaluated precisely and inexpensively.
■ aus Plug & Play Monitoren die EDID Informationen wie Herstelleridentifikation, Display Parameter usw. durch den DDC Kanal ausliest und entschlüsselt.■ reads and decodes the EDID information such as manufacturer identification, display parameters, etc. from Plug & Play monitors via the DDC channel.
■ TTL Signale auf \hi periodisches Verhalten wie Frequenz, Stabilität, Polarität usw. untersucht.■ TTL signals are examined for periodic behavior such as frequency, stability, polarity, etc.
■ von der Grafikkarte geforderte Power Saving Phasen anzeigt (laut DPMS-Vorschrift: off, on, standby und suspend).■ displays the power saving phases required by the graphics card (according to DPMS regulations: off, on, standby and suspend).
■ neben der Periodizität zweier TTL Signale auch ihr Koinzidenzverhalten prüft.■ checks not only the periodicity of two TTL signals but also their coincidence behavior .
■ anhand der Synchronisationssignale (gravierendstes Störsignal beim Monitor) das Spektrum der zu erwartenden Störaussendung durch FFT-Analyse errechnet.■ Based on the synchronization signals (most serious interference signal in the monitor), the spectrum of the expected interference emission is calculated using FFT analysis.
■ die Ergebnisse in unterschiedlichen Formen darstellt, speichert und protokolliert. ■ presents, stores and records the results in different forms.
- Bildwiederholrate - Bandbreite (Pixelfrequenz)- Refresh rate - Bandwidth (pixel frequency)
- Zeilenfrequenz . Bildlage (Front- und Back-Porch)- Line frequency . Image position (front and back porch)
- Polarität, Dauer und Breite der Signale - Bildgröße (ActiveVideo- u. Blanking-Time)- Polarity, duration and width of the signals - Image size (ActiveVideo and Blanking Time)
- Zeilensprung-Techik (interlaced/non int.) - Power Saving Phase (on, standby, suspend...)- Interlaced technology (interlaced/non int.) - Power saving phase (on, standby, suspend...)
- Zeilenmodus - EDID Informationen eines P&P Monitors- Line mode - EDID information of a P&P monitor
- Übereinstimmung mit einem Standard - Merkmale zwei TTL periodischen Signale- Compliance with a standard - Features two TTL periodic signals
- Bildauflösung in Punkten (Zeilen/Spalten) - Die zu erwartende Störaussendung (FFT)- Image resolution in points (rows/columns) - The expected interference emission (FFT)
Die zeitlichen Abläufe werden den Konventionen entsprechend in unterschiedlichen Formen (Grafik, Tabelle) und Maßeinheiten präsentiert (z.B. als Periodendauer in Sekunden, &EEgr;-Sync bzw. Pels, Frequenz oder ihr Verhältnis zu duty cycle)The temporal sequences are presented in accordance with the conventions in different forms (graphics, table) and units of measurement (e.g. as period duration in seconds, �EEgr;-Sync or Pels, frequency or its relationship to duty cycle)
■ Die Anwender können endlich das Bestmögliche aus ihrem Monitor-Grafikkarte- Tandem heraus holen. ■ Users can finally get the best out of their monitor-graphics card tandem.
Bandbreite, Synchronisationsfrequenz-Bereich, Anzahl der Farben setzen die Grenzen. Welcher Monitortyp, bei welcher Punkt- und Farbauflösung, liefert die meiste Information und ein ruhiges Bild? Grafikkarten allein geben nicht die richtige Antwort. "Der Monitor macht noch mit": das reicht nicht. Die Zerstörung des Gerätes ist nicht ausgeschlossen.Bandwidth, synchronization frequency range, number of colors set the limits. Which monitor type, with which pixel and color resolution, delivers the most information and a smooth image? Graphics cards alone do not provide the right answer. "The monitor still works": that is not enough. The destruction of the device cannot be ruled out.
■ Die Techniker sparen teuere Instrumente und kostbare Zeit ein.■ Technicians save expensive instruments and valuable time.
Frequenzzähler, Speicheroszillograph, Signalanalysator, PC Schnittstelle. Kein langwieriger Meßaufbau, keine Eichung, Bereicheinstellung. Abgeleitete Größen (Interlaced, Bandbreite, Spektrum der Störaussendungen...) werden aus den Meßwerten direkt errechnet.Frequency counter, storage oscillograph, signal analyzer, PC interface. No lengthy measurement setup, no calibration, no range setting. Derived quantities (interlaced, bandwidth, spectrum of interference emissions...) are calculated directly from the measured values.
■ Produktmanager können (im Handumdrehen) Qualitätskontrollen durchführen und bei P&P Monitoren an die Herstelleridentifikationen herankommen.■ Product managers can perform quality control checks (in a snap) and access manufacturer identification for P&P monitors.
