The Keysight N7001A InfiniiMax III+ Series Probe Amplifier delivers 13 GHz bandwidth for high-speed differential bus probing. InfiniiMode technology enables simultaneous measurement of differential, single-ended (A or B), and common-mode signal components through a single probe connection, eliminating the need for multiple connections. Each amplifier is loaded with measured S-parameters that combine with probe head S-parameters to flatten magnitude and phase response, delivering superior AC correction and measurement fidelity.
Technical Specifications
• Bandwidth: 13 GHz
• Probe Interface: AutoProbe 2
• Differential Input Impedance: 100 kΩ / 0.32 pF
• Input Impedance Profile: RCRC (optimized for low source impedance)
• Attenuation Range: 5:1 / 10:1
• S-Parameters: Loaded with measured values for enhanced AC correction
– Key Features
• InfiniiMode Technology provides four measurement modes from one probe connection:
– Differential mode: A − B
– Single-ended A: A − ground
– Single-ended B: B − ground
– Common mode: (A+B)/2 − ground
• Measured S-parameters enable accurate probe correction across the measurement chain
• RCRC input impedance profile minimizes loading effects on low-impedance sources
– Typical Applications
The N7001A addresses high-speed differential signal characterization in digital buses, memory interfaces, and serial communication standards where probe loading and signal fidelity are critical.
