Industry’s most comprehensive extreme-temperature chamber testing solutions for oscilloscopes
N2797A Extreme Temperature Active Probe
Many engineers have a need to monitor their product 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.
Until now, testing in extreme temperature ranges required engineers to use probes outside their specified operating temperatures, which can damage probes. Most active or passive probes in the market have a specified operating temperature range anywhere from 0 to 50 °C. However, Keysight’s N2797A extreme temperature active probe can be operated over a much wider –40 to +85 °C range. This allows you to operate the probe head and the supplied probing accessories inside a temperature chamber with the probe pod and oscilloscope located outside the temperature chamber.
N5450A InfiniiMax Extreme Temperature Extension Cable
For extended temperature testing with more extreme temperature range measurements, Keysight offers the N5450B InfiniiMax extreme-temperature extension cable with the InfiniiMax Series differential probing system, which gives engineers the ability to probe signals at even wider temperature ranges. When used with the Keysight N5381A differential solder-in probe head, this solution provides engineers with the widest temperature range coverage of –55 to 150 °C, which is the maximum temperature range specified for automotive electronics testing.
N2820A/21A High-Sensitivity Current Probes
When accurate and repeatable current measurements inside the chamber are critical over wide temperature ranges, the N2820A/21A high-sensitivity current probes are the best choice, especially for precision current measurement applications. When the user-defined head is used with the N2820A/21A current probe, it provides the industry’s highest sensitivity current measurement solution among oscilloscope current probes, going all the way down to 50 uA with a maximum current range of 5 A operating over the temperature range of –55 to 150 °C.
This probing solution provides an ideal solution for engineers who need to validate and characterize their designs while operating within extreme temperature ranges, especially those working in the semiconductor, consumer, wireless mobile devices, automotive electronics, and computer industries.
N7007A Extreme Temperature Passive Probe
The N7007A 400 MHz passive probe is a low-cost, high impedance passive probe with rugged probe tips for environmental chamber testing from -40 to +85 °C. Its large input impedance (10 MΩ @ DC) and wide input voltage range (1,000 Vdc + peak AC CATII) makes the probe ideal for a broad range of general purpose extreme temperature applications.
N7013A Extreme Temperature Extension Kit for Differential Probes
The N7013A is a 70 cm long extreme temperature extension kit compatible with four of Keysight’s medium- & high-voltage differential active probes including the N2790A, N2791A, N2792A and N2818A. These probes are typically used in power supply testing applications, as well as testing automotive differential buses including CAN, CAN FD, and FlexRay. With the N7013A extension kit, the extension cables and connection adapters can be extended into the environmental chamber under extreme-temperature conditions ranging from -40 to +85 °C.
This extreme temperature probing solution provides an ideal solution for engineers working with the semiconductor, consumer, wireless mobile devices, automotive electronics, and computer industries who need to validate and characterize their designs while operating within extreme temperature ranges. Keysight now offers the broadest selection of extreme-temperature oscilloscope probing solutions in the market.
