Introduction
This quick start guide provides the basic information, front panel functions 
and general specifications of Agilent U1600B Series handheld digital 
oscilloscopes. The U1600B Series can also function as a digital multimeter 
(DMM) and data logger. With its 4.5- inch LCD color display, it is capable of 
clearly distinguishing waveforms from two channels. The U1600B Series 
handheld digital oscilloscopes are high performance troubleshooting tools in 
multi- industrial automation, process control, facility maintenance and 
automotive- service industries. The U1600B Series comprises two models: 
U1602B and U1604B, with 20 MHz and 40 MHz bandwidths, respectively. Both 
models are dual- channel scopes with 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 U1604B) to perform a quick waveform analysis 
in both time and frequency domain. The U1600B Series with built- in 6000-
count resolution and true RMS comes with an auto range function that allows 
users to perform quick and accurate DMM measurements. Additionally, with 
data logger function, users can perform automatic data logging for all DMM 
measurements.
