U1604B - 

Keysight U1600 Series Handheld Digital Oscilloscopes
The U1600 Series handheld digital oscilloscope has a 4.5-inch LCD color display, which helps to clearly distinguish waveforms between two channels. This U1600 Series provides a high performance troubleshooting and quality assurance tool for technical professionals in the installation, maintenance, service, and automotive industries. The U1600 Series consists of four models: U1602A/U1602B — 20 MHz oscilloscope and U1604A/U1604B — 40 MHz oscilloscope. Each model has a real-time sampling rate of up to 200 MSa/s. Users can use the Dual Waveform Math (DWM) and Fast Fourier Transform (FFT) functions (in the U1604A/U1604B model) to perform quick waveform analyses in both time and frequency domains.
The built-in 6000 resolution count true RMS digital multimeter (DMM) comes with an auto-range feature that gives users the flexibility to perform quick and accurate meter measurements including voltage, resistance, and auxiliary measurements. In addition, the standard versions of the U1600 Series models also contain a data logger function. The series? latest oscilloscopes, the U1602B and U1604B come in vivid orange cases, offering capabilities and functions equivalent to the U1600A Series.
