The Keysight 1130B is a 1.5 GHz probe amplifier engineered for high-speed differential and single-ended probing of low-impedance circuits. Part of the InfiniiMax series, it delivers ultra-low DUT loading through patented resistor probe tip technology, minimal input capacitance, and flat frequency response. The 1130B is the RoHS-compliant successor to the 1130A, offering 100% form, fit, and function equivalence while supporting modern Keysight oscilloscope platforms.
– Technical Specifications
• Probe Bandwidth: 1.5 GHz
• System Bandwidth: 1 GHz (with 1 GHz oscilloscopes)
• Attenuation Ratio: 10:1 / 5:1 selectable
• Dynamic Range: ±2.5 V
• DC Offset Range: ±12 V (with probe offset)
• Maximum Input Voltage: ±30 V peak (mains isolated circuits)
• Input Impedance (Differential): 50 kΩ resistance, 0.27–0.34 pF capacitance
• Input Impedance (Single-Ended): 25 kΩ resistance, 0.44–0.67 pF capacitance
– Key Features
• Patented resistor probe tip technology minimizes loading
• Low input capacitance reduces DUT interaction
• Flat frequency response ensures signal integrity across the measurement band
• AutoProbe interface enables automatic probe configuration and power delivery
• Dual attenuation modes (10:1 and 5:1) for flexible dynamic range
– Compatibility & Integration
The 1130B integrates with Infiniium oscilloscopes (600 MHz to 1 GHz and higher with A.03.10+ software) and InfiniiVision oscilloscopes (500 MHz to 1 GHz). A complete probing system requires one or more probe heads or connectivity kits such as the E2669B differential/single-ended kit or E2675B differential browser kit. AutoProbe interface support ensures plug-and-play operation with compatible instruments.
