Differential TDR module

Manufacturer's part number :

54754A

Manufacturer Agilent Technologies

Keysight Technologies

Description :

The Keysight 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.

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.

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 module’s trigger output to the mainframe’s 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 main frame with option STR.
