Differential amplifiers are intended to act as signal conditioning preamplifiers for oscilloscopes and network and spectrum analyzers, providing differential measurement capability to instruments having only a single-ended input. The -PR2 version of each amplifier is a dual channel unit. The DXC series differential input cables are matched to the characteristics of the amplifier.

Wide oscilloscope compatibility
Transmission line probes are a special type of passive probe designed for use at very high frequencies. They replace the high impedance probe cable found in a traditional passive probe with a precision transmission line, with a characteristic impedance that matches the oscilloscope input (50 Ohm). This greatly reduces the input capacitance to a fraction of a picofarad, minimizing the loading of high frequency signals. A matching network at the tip increases the DC input resistance. While they have lower DC input resistance than a traditional passive probe (usually 500 Ohm) to 5 kOhm), the input impedance of these probes remains nearly constant over their entire frequency range. A traditional /10 passive probe will have a 10 MOhm) input impedance at DC, however this impedance drops rapidly with frequency, passing below the input impedance of a transmission line probe at less than 100 MHz.

Teledyne LeCroy
Teledyne LeCroy is a leading provider of oscilloscopes, protocol analyzers and related test and measurement solutions that enable companies across a wide range of industries to design and test electronic devices of all types. Since our founding in 1964, we have focused on creating products that improve productivity by helping engineers resolve design issues faster and more effectively.
Oscilloscopes are tools used by designers and engineers to measure and analyze complex electronic signals in order to develop high-performance systems and to validate electronic designs in order to improve time to market. Protocol analyzers are tools used by designers and engineers to generate and monitor traffic over high speed serial data interfaces, including DDR, PCI Express, Fibre Channel, Serial ATA, SAS, USB and others. Both products are critical in the development of a wide variety of demanding design applications.
We utilize both of these important product areas in combination to tackle the most demanding serial data test applications, offering tailored solutions to help our customers perfect their chips, interfaces, subsystems and products which utilize these important communications standards. With the explosion in the use of serial data communications technologies in semiconductors, between devices on circuit boards and between computers and peripherals, we are aimed at a growing and important market.
Our oscilloscopes offer a powerful combination of large and informative displays combined with advanced waveshape analysis capabilities typically tailored to enhance the productivity of engineers in specific applications areas such as serial data test, disk drive test and automotive bus analysis.
Headquartered in Chestnut Ridge, New York, LeCroy has sales, service and development subsidiaries in the US and throughout Europe and Asia. LeCroy products are employed across a wide variety of industries, including semiconductor, computer, consumer electronics, military/aerospace, automotive/industrial, and telecommunications.
