Keysight 33511B Waveform Generator – 20 MHz 1-Ch 33511B with Arb

Description

Product Overview

• Keysight 1146B is an AC/DC current probe for 100 A and 100 kHz.
• It uses Hall-effect sensor technology to measure AC and DC signals.
• You can measure without breaking the circuit.
• This probe replaces the discontinued 1146A with same fit and function.

Key Features

• Frequency range: DC to 100 kHz (-3dB with current de-rating)
• Maximum peak current: 100 A DC or peak AC (at 10 mV/A setting)
• Two sensitivity ranges: 100 mV/A (10A range) and 10 mV/A (100A range)
• Working voltage: 600 V maximum
• Battery: 9 V alkaline (user replaceable)
• Compatible with any Keysight oscilloscope (0.2 to 0.5 V/div, 1 MΩ BNC input)

Technical Specifications

• Model: Keysight 1146B
• Type: AC/DC Current Probe
• Frequency Response: DC to 100 kHz (-3dB)
• Max Current (10 mV/A setting): 100 A DC or peak AC
• Max Current (100 mV/A setting): 10 A DC or peak AC
• Accuracy (100 mV/A, 50mA to 10A peak): ±3% of reading (≥50mA)
• Accuracy (10 mV/A, 500mA to 40A peak): ±4% of reading (≥50mA)
• Accuracy (10 mV/A, 40A to 100A peak): 15% max at 100A
• Working Voltage: 600 V maximum
• Power Source: 9 V alkaline battery
• Output Connection: BNC (1 MΩ input required)

Compatibility & Installation

• Works with all Keysight oscilloscopes having 1 MΩ BNC input.
• Sensitivity requirement: 0.2 to 0.5 V/div on the oscilloscope.
• No calibration needed before use – just connect and set range.
• Battery life indicator helps avoid unexpected shutdowns.

5 Professional FAQs

• Can I measure both AC and DC current at the same time?
• Yes. The probe outputs the total waveform including DC offset and AC ripple.
• Why does accuracy drop above 40A on the 100mV/A range?
• The 100mV/A range is designed only for currents up to 10A. Use 10mV/A range for high currents.
• How do I know when to replace the battery?
• Low battery affects accuracy. Replace the 9V alkaline when the green LED dims or flickers.
• Can I use this probe with non-Keysight oscilloscopes?
• Yes. Any oscilloscope with 1 MΩ BNC input and 0.2 V/div sensitivity works.
• What shipping methods do you offer for this probe?
• We ship via FedEx, UPS, or DHL worldwide. Tracking provided.

Buying Guide & Warranty

• Warranty: 12 months from shipment date against defects.
• Genuine Keysight 1146B – fully tested, not a clone.
• Best for motor controllers, switching power supplies, inverters, and inductive loads.
• Includes 9V battery – ready to use out of the box.
• BNC cable length: approx 1.5 meters (standard).
