Agilent 54753A Single Ended TDR/TDT for the Agilent 54750A High-Bandwidth Digitizing Oscilloscope
The Agilent 54753A oscilloscope is a graph-displaying device – it draws a graph of an electrical signal. In most applications, the graph shows how signals change over time: the vertical (Y) axis represents voltage and the horizontal (X) axis represents time. The intensity or brightness of the display is sometimes called the Z axis.
The Agilent 54753A oscilloscope's simple graph can tell you many things about a signal, such as: the time and voltage values of a signal, the frequency of an oscillating signal, the “moving parts” of a circuit represented by the signal, the frequency with which a particular portion of the signal is occurring relative to, other portions, whether or not a malfunctioning component is distorting the signal, how much of a signal is direct current (DC) or alternating current (AC) and how much of the signal is noise and whether the noise is changing with time.
The HP 54753A is a two-channel vertical plug-in with a TDR step generator built into channel one. The bandwidth of the TDR/vertical channel is 18 GHZ. The bandwidth of channel two is 20 GHz. The step generator provides a 200 mV TDR step with a system rise time of <45 ps. The system has the ability to normalize the
TDR by applying a digital filter. Normalization removes errors caused by loss or imperfect launchers or cables.
The rise time of the normalization filter may be varied to allow you to simulate the edge speeds found in your system. You may also push the rise time up to 10 ps. Unlike the HP 54120 series, the normalization filter when activated processes every acquisi-tion so you see changes as the DUT is adjusted.
The HP 54753A provides support for external step generators, such as the PicoSecond Pulse Labs 4015C.
