With input impedance of 10 MΩ and 400 MHz bandwidth, N7007A is 2 m long, single-end, 10:1 passive probe used for probing electrical signals inside temperature chamber. As extension kit, 70 cm-long N7013A includes 4 medium- and high-voltage differential active probes: N2790A (±1,500 V), N2791A (±700 V), N2792A (±20 V), and N2818A (±20 V). Engineers can place main body of probe outside environmental chamber and use extension kit and connection adapters to extend probes into environmental chamber.
