Product Description:
Agilent Technologies, Inc. 54754A Differential TDR module
The Agilent Technologies, Inc. 54754A 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 Technologies, Inc. 54754A 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.

Description
The Agilent 54754A provides two 18-GHz channels that have built-in TDR step generators. The two channels may work in tandem to provide differential or common mode TDR stimulus/response, or may be used independently. Either channel works as a normal oscilloscope vertical system when the TDR/TDT step generators are not operating.
To protect your investment, you may want to consider using an ESD Protective device such as the one available from Picosecond ATE.
Probing And Calibration
Accurate probing of high-speed differential circuits can be a challenge. It is important to use a differential TDR probe with the correct bandwidth, pitch, signal configuration, etc. to match your design.

System configuration:
All 86100A/B/Cs and the 86100D in the ETR configuration have a internal trigger connections between modules and the mainframe. 86100Ds with option STR do not and therefore require an external cable (such as P/N 5062-6690) from the TDR modules trigger output to the mainframes trigger input. Use a power splitter (such as P/N 11667B) or divider (such as P/N 11636B) when using two TDR modules in an 86100D mainframe with option STR.
