60 V Common Mode Differential Probes
The 60 V Common Mode Differential Probes are the ideal probes for lower voltage GaN power conversion measurement with the highest accuracy, best CMRR, and lowest noise.
Active Voltage Probes
Engineers must commonly probe high-frequency signals with high signal fidelity. Typical passive probes with high input R and C provide good response at lower frequencies, but inappropriately load the circuit, and distort signals, at higher frequencies. Active voltage probes feature both high input R and low input C to reduce circuit loading across the entire probe/oscilloscope bandwidth. With low circuit loading, and a form factor that allows probing in confined areas, the active voltage probe becomes the everyday probe for all different types of signals and connection points.
Active Voltage Rail Probe
The RP4030 is designed specifically to probe a 50Ω DC power/voltage rail. The probe has large built-in offset, low attenuation (noise), and high DC input impedance. Built-in offset and low attenuation permit the power/voltage rail to be offset in the oscilloscope by its mean DC voltage with high oscilloscope gain (sensitivity) to achieve a noise-free view of small signal variations. The high DC input impedance eliminates loading of the DC rail.
T3RC Rogowski Coil Current Probes
Teledyne Test Tools Rogowski Current probes offer a broad range of products covering a wide frequency span and current measurement ranges for maximum application coverage whilst being easy to use in difficult to reach parts of the circuit.
Current Probes
Teledyne LeCroy current probes do not require the breaking of a circuit or the insertion of a shunt to make accurate and reliable current measurements. Based on a combination of Hall effect and transformer technology, Teledyne LeCroy current probes are ideal for making accurate AC, DC, and impulse current measurements.
Differential Probes (<= 1.5 GHz)
Differential active probes are like two probes in one. Instead of measuring a test point in relation to a ground point (like single-ended active probes), differential probes measure the difference in voltage of a test point in relation to another test point
Differential Probes (4-6 GHz)
Differential active probes are like two probes in one. Instead of measuring a test point in relation to a ground point (like single-ended active probes), differential probes measure the difference in voltage of a test point in relation to another test point.  Dx10/Dx20/Dx00A-AT 4-6 GHz differential probes are a general purpose probing solution with high input dynamic range and offset.
Differential Probes (8-30 GHz)
The DH series of 8 to 30 GHz active differential probes provides high input dynamic range, large offset capability, low loading and excellent signal fidelity with a range of connection options.
High Voltage Differential Probes
High voltage differential probes provide high CMRR over a broad frequency range (up to 400 MHz) to simplify the measurement challenges found in noisy, high common-mode power electronics environments. The probe’s design is easy-to-use and enables safe, precise high voltage floating measurements.
High Voltage Fiber Optically-isolated Probes
The new HVFO108, with 150 MHz of bandwidth, is suitable for both Silicon and Silicon Carbide designs. It is designed to measure small signals floating on an HV bus and delivers excellent performance, has high CMRR, and provides optical isolation to reduce DUT loading.
High Voltage Passive Probes
High voltage single-ended passive probes are suitable for a wide range of applications where ground-referenced high-voltage measurements must be made safely and accurately. There are several fixed-attenuation probes covering a range from 1 kV to 6 kV and varying transient overvoltage ratings. All of these high voltage probes feature a spring loaded probe tip and a variety of standard accessories to make probing high voltages safe and easy. Additionally, all of the high voltage probe have a probe sense pin to automatically configure the oscilloscope for use with the probe.
Optical to Electrical Converters
Teledyne LeCroy's wide-band multi-mode optical-to-electrical converters are designed for measuring optical communications signals. Their broad wavelength range and multi-mode input optics make these devices ideal for applications including Ethernet, Fibre Channel, and ITU telecom standards.  Available to support optical data rates up to 11.3 Gb/s with reference receivers, or slightly higher without reference receivers.
Passive Probes
Passive probes are the standard probe provided with most oscilloscopes. Typical passive probes provide a /10 attenuation and feature a high input resistance of 10 MOhm. This high input resistance means that passive probes are the ideal tool for low frequency signals since circuit loading at these frequencies is minimized. Passive probes are designed to handle voltages of at least 400 V, some as high as 600 V. Teledyne LeCroy passive probes feature an attenuation sense pin which tells the oscilloscope to scale the waveforms automatically requiring no user input.
Probe Adapters
Probe adapters provide simple and easy interface of third-party probes as well as change between the different Teledyne LeCroy Oscilloscope input and cable types (ProBus, ProLink, K/2.92 mm, BNC and SMA). Depending on the adapters, changing between the Teledyne LeCroy Oscilloscope's input type may have an effect on the overall performance of the channel.
Probe Parts and Kits
There are a variety of replacement and additional probe parts, tips and accessories
Transmission Line Probes
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.
