Types of Probes

	Optical to Electrical Converter Keysight optical-to-electrical converter is designed for direct optical-to-electrical conversion of optical telecom or data com signals into the Infiniium realtime oscilloscope. When used with the Infiniium V or Z Series 33 GHz oscilloscope, the N7004A allows users to view optical streams at speeds up to 28 Gbps, making this the ideal solution for characterizing or troubleshooting high speed optical signals in the system level testing.
	Active Differential Probes A differential probe is an active probe that has two inputs, one positive and one negative, as well as a separate ground lead; it drives a single-terminated 50Ω cable to transmit its output to one oscilloscope channel. The output signal is proportional to the difference between the voltages appearing at the two inputs. A differential probe is used to look at signals that are referenced to each other instead of earth ground and to look at small signals in the presence of large DC offsets or other common mode signals such as power line noise. Various models in InfiniiMax probing system provide versatile probing solutions for differential probing. InfiniiMax probes consist of probe amplifiers and a large assortment of probing heads that attach to the probe amplifiers. All InfiniiMax probes connect to the oscilloscope using an AutoProbe interface.
	Active Differential Probes (InfiniiMode) InfiniiMode compatible probes allow convenient measurements of differential, single ended, and common mode signals with a single probe tip without reconnecting the probe to change the connection. These are compatible with the Infiniium oscilloscope's AutoProbe interface, which completely configures the Infiniium series of oscilloscopes for the probes.
	Single Ended Probes Single-ended active probes contain a small, active amplifier built into the probe body near the probe tip. This arrangement makes it possible to keep the probe input capacitance very low, usually less than 2 pF. This low capacitance results in high input impedance on high frequencies. It has the best overall combination of resistive and capacitive loading. With such low loading, active probes can be used on high-impedance circuits that would be seriously loaded by passive probes. Active probes are the least intrusive of all the probes. The InfiniiMax probing system provides a versatile probing solution for single-ended active probing. InfiniiMax probes consist of probe amplifiers and a large assortment of probing heads that attach to the probe amplifiers. All InfiniiMax probes connect to the oscilloscope using an AutoProbe interface. The 1131/2/4B InfiniiMax probes and the 1168B/69B InfiniiMax II probes require the N5442A adapter to be compatible with the 90000 X-Series oscilloscope.
	Current Probes Current probes sense the current flowing through a conductor and convert it to a voltage that can be viewed and measured on an oscilloscope. Keysight current probes use a hybrid technology that includes a Hall-effect sensor, which senses the DC current, and a current transformer, which senses the AC current. Using split core construction, the current probe easily clips on and off of a conductor, making it unnecessary to make an electrical connection to the circuit. Measurement bandwidths from DC to 100 MHz are available.
	Passive Probes The most widely used type of oscilloscope probe is the passive probe. Passive probes are also the most rugged and economical. There are no active components such as transistors or amplifiers in the probe, and therefore passive probes do not need to be powered. The Probe ID indicates auto readout for probe attenuation ratio.
	High Voltage Differential Probes Both passive and active high-voltage probes are available. To ensure safe operation, read the user's guide before using the probe. High voltage differential probes allow for safe and accurate floating signal measurements between two voltage points where neither point is referenced to ground. Enabled by high CMRR, a high voltage differential probe simplifies the measurement challenges found in noisy, high common-mode power electronics environments.
	TDR Probes TDR probes are specifically designed for use with an 86100C/D sampling oscilloscope placed in TDR/TDT mode. TDR/TDT mode requires a 54753A single-ended TDR/TDT module or a 54754A differential TDR/TDT module be installed in the oscilloscope.
	Extreme Temperature Probing Many engineers have a need to monitor their products in an environmental chamber with an oscilloscope probe to verify performance over a wide range of operating temperatures or to determine the cause of failures at high or low temperatures.
