Prevention of fire or injury:
• Use only the designated AC adapter and test leads
supplied with the instrument.
• Observe all ratings and markings of the instrument
before connecting to the instrument.
• When performing measurement, ensure that the
right safety and performance ratings of instrument
and accessories are used.
• Connect the scope probe or test leads to
instrument before connecting to any active circuit
for testing. Before disconnecting the active circuit
from instrument, remove scope probe or test leads
from active circuit.
• Do not connect the ground wire to voltages higher
than 42 Vpeak (30 Vrms) from earth ground.
WARNING
Maximum Input Voltages
Maximum Floating Voltage
• From any terminal to ground — 300 Vrms CAT III
(up to 400 Hz)
• Input CH1 and CH2 direct (1:1 Probe) — 300 V CAT III
• Input CH1 and CH2 via 1:10 Probe — 600 V CAT III
• Input CH1 and CH2 via 1:100 Probe — 600 V CAT III
• Meter Input — 300 V CAT III, 600 V CAT II
• Scope Input — 300 V CAT III
• Voltage ratings are Vrms (50 Hz - 60 Hz) for AC sine
wave and VDC for DC applications.
• Do not expose the circuit or operate the instrument
without its cover or while power is being supplied.
• Do not use exposed metal BNC or banana plug
connectors, use only the insulated voltage probes,
test leads and adapters that come with the
instrument.
• Do not supply any voltage when measuring
resistance or capacitance in meter mode.
• Do not operate the instrument if it does not operate
properly, have the instrument inspected by qualified
service personnel.
• Do not operate the instrument in wet or damp
environments.
• Do not operate the instrument in any environment
in a risk of explosion.
• Maintain a clean and dry condition to the
instrument’s surface.
Prevention of electro-static discharge
• Electro-static discharge (ESD) can result in damage
to the components in the instrument and
accessories.
• Select a static-free working location when installing
and removing sensitive components.
• Handle sensitive components to the minimum
extent possible. Do not allow contacts between
components and exposed connector pins.
• Transport and store in ESD preventive bag or
container that protects sensitive components from
static electricity.

A new rechargeable battery comes in a discharged condition and must be charged
before use (refer to the U1602A and U1604A User's and Service Guide for charging
instructions). Upon initial use (or after a prolonged storage period) the
rechargeable battery may require three to four charge/discharge cycles before
achieving maximum capacity. To discharge, simply run the oscilloscope using the

Introduction
This quick start guide provides the basic information, front panel functions
and general specifications of Agilent U1600A Series handheld digital
oscilloscopes. The U1600A 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 U1600A Series
handheld digital oscilloscopes are high performance troubleshooting tools in
multi- industrial automation, process control, facility maintenance and
automotive- service industries. The U1600A Series comprises two models:
U1602A and U1604A, 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 U1604A) to perform a quick waveform analysis
in both time and frequency domain. The U1600A 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.

To Charge a Battery
Upon delivery of the unit, the rechargeable
battery is required to be fully charged for
approximately 25 hours with the
designated Agilent AC adapter. Ensure that
you have the correct line power cord. The
AC adapter converts input line voltages
ranging from 100 VAC to 240 VAC to
output voltage 12 VDC.
Input: 100 V – 240 VAC
Output: 12 VDC, 2 A,
50/60 Hz
To Power On the Handheld Scope
To turn on or off the scope, press and hold the
power switch button for three seconds. A
basic self-test shall be executed
automatically upon power up. The scope will
be loaded with the last configuration setup of
the scope.
