Operable in temperatures from -40°C to +85°C
Announcement of Temperature Probing and Extreme Temperature Expansion Kit

Keysight Korea (CEO Deok-Kwon Yoon) introduced two new extreme temperature probing solutions: the N7007A extreme temperature passive probe and the N7013A extreme temperature expansion kit for medium-to-high voltage differential active probes.

These probes operate up to a band of 400 MHz and are ideal for probing electrical signals in temperature chambers. The two newly introduced products are compatible with Keysight's InfinilVision and Infiniium series, expanding the range of options for extreme temperature oscilloscope probing solutions.

Today, most electronic products must be tested under various environmental conditions, including extreme temperatures. Most test devices and passive or active probes were only capable of operating at temperatures between 0 and 55 degrees. In contrast, extreme temperature testing is generally conducted from -40 to 85 degrees. Therefore, environmental test engineers could not place the probe and equipment together in the test chamber if the temperature limits specified in the probe specifications were exceeded.


Dave Cipriani, Head of the Oscilloscope and Protocol Division at Keysight, stated, "When conducting environmental tests on electronic products, engineers must ensure that the equipment they use can withstand extreme temperature conditions." He added, "Keysight's extreme temperature probing systems are ideal for engineers seeking to verify that their designed products can operate at various temperatures. With Keysight test solutions, engineers can obtain more accurate measurement results in extreme environments, enabling them to accurately predict the long-term performance and functionality of their products."

Today, because many engineers use standard temperature probes in extreme environments, products are susceptible to physical damage. Another constraint for environmental engineers is connecting long wires to the ends of probes, which causes critical defects in product performance, resulting in reduced bandwidth or excessive inductance. Keysight has solved this problem with an external kit combining the N7007A single-ended passive probe and the N7013A differential active probe.

The N7007A is 2m long and uses a microcurrent of 10 microohms and a bandwidth of 400MHz. This equipment can be operated at temperatures ranging from -40 degrees to +85 degrees. This probe is ideal for various operations at extreme temperatures, and its length is ideal for probing hard-to-reach test points in automotive applications.

The N7013A is a 70cm extreme temperature extension kit compatible with four Keysight medium-to-high voltage differential active probes, including the N2790A (±1500 V), N2791A (±700 V), N2792A (±20 V), and N2818A (±20 V). These probes are used for automotive differential bus testing, including CAN, CAN FD, and FlexRay, as well as primarily for power supply test applications. The N7013A external kit allows engineers to install it on the main body of the temperature-sensing differential active probe located outside the environment chamber and connect the probe to an environment chamber adjustable from -40°C to +85°C using the external kit (a pair of 70cm cables) and a connection adapter.
