The Keysight (Agilent) N7003A InfiniiMax III+ Series Probe Amplifier delivers 20 GHz bandwidth for high-speed differential bus probing and signal integrity measurements. This probe amplifier combines high fidelity with extremely low loading to capture accurate waveforms in demanding test environments.
– Technical Specifications
• Bandwidth: 20 GHz maximum frequency
• Differential Input Impedance: 100 kΩ / 0.32 pF
• Impedance Profile: RCRC (optimized for low source impedance signals)
• Attenuation Options: 5:1 / 10:1
– Key Features
InfiniiMode Technology enables differential, single-ended (A or B to ground), and common-mode ((A+B)/2 to ground) measurements through a single probe connection. Mode switching occurs via the oscilloscope’s probe configuration dialog box without requiring physical probe reconfiguration.
Measured S-Parameter Correction loads the probe amplifier with measured S-parameter data. Combined with probe head S-parameters, this delivers more accurate AC correction and flatter magnitude and phase response across the measurement bandwidth, resulting in precise characterization of high-speed signals.
The combination of 20 GHz bandwidth and extremely low loading ensures high-fidelity signal acquisition with minimal impact on circuit operation.
– Typical Applications
• General-purpose high-speed differential bus probing
• Signal integrity measurements on demanding electrical test benches
• Multi-mode measurement scenarios requiring flexible probe configuration
