Agilent/Keysight U1620A

The Agilent/Keysight U1620A is a handheld digital oscilloscope that combines a dual-channel oscilloscope, digital multimeter, and data logger into a single field-portable instrument. Built for field service, electronic troubleshooting, and educational use, it delivers 200 MHz bandwidth with real-time sampling to 2 GSa/s and captures up to 2 Mpts of waveform memory. The 5.7-inch VGA TFT LCD color display adapts to indoor, outdoor, and low-light conditions, while channel-to-channel isolation enables floating measurements at CAT III 600 V safety ratings.
