General Safety Information
WARNING
WARNING
WARNING
The following general safety precautions must be observed during all phases of
operation of this instrument. Failure to comply with these precautions or with
specific warnings elsewhere in this manual violates safety standards of design,
manufacture, and intended use of the instrument. Keysight Technologies assumes
no liability for the customer’s failure to comply with these requirements.
– Remove all unused scope (oscilloscope) probes, DMM (digital
multimeter) test leads, or USB cable.
– Do not connect the DMM test leads and scope probes at the same time.
– Disconnect the scope probe from the instrument before using the DMM
functions.
– Disconnect the DMM test leads from the instrument before using the
scope functions.
To avoid electrical shock or fire during battery replacement:
– Disconnect test leads, probes, power supply, and USB cable before
opening case or battery cover.
– Do not operate the instrument with the battery cover open.
– Use only specified insulated probes and test leads.
– Use only the 10.8 V Li-Ion battery pack supplied with the instrument.
To prevent fire or injury:
– Use only the designated AC/DC adapter and test leads supplied with the
instrument.
– Observe all ratings and markings on the instrument before connecting to
the instrument.
– When performing measurements, ensure that the right safety and
performance ratings of instrument and accessories are used.

WARNING
– Plug the probe or test leads to the instrument before connecting to any
WARNING
active circuit for testing. Before disconnecting from the instrument,
remove the probe or test leads from the active circuit.
– Do not connect the USB cable when not in use. Keep the USB cable away
from any probe, test lead, or exposed circuitry.
– 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 supplied with the
instrument.
– Do not supply any voltage when measuring resistance or capacitance in
multimeter 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 at risk of explosion. Do
not operate the instrument in the presence of flammable gases or flames.

CAUTION
– If the instrument is used in a manner not specified by the manufacturer,
CAUTION
the instrument protection may be impaired.
– Always use a dry cloth to clean the instrument. Do not use ethyl alcohol
or any other volatile liquid.
– It is recommended to use the instrument under ventilated conditions and
in the upright position to ensure adequate airflow at the rear.
– Always cover the DC power inlet and the USB port by closing the lid when
not in used.
Electrostatic discharge (ESD) can result in damage to the components in the
instrument and accessories. To prevent electrostatic discharge (ESD):
– Select a static-free work location when installing and removing sensitive
equipment.
– Handle sensitive components to the minimum extent possible. Do not
allow contacts between components and exposed connector pins.
– Transport and store in ESD preventive bags or containers that protect
sensitive components from static electricity.
– The battery (optional) must be properly recycled or disposed.

Introduction
The U1610/20A Handheld Digital Oscilloscope is a mobile high-performance
troubleshooting tool for multi-industrial automation, process control, facility
maintenance, and automotive-service industries.
The U1610A and U1620A models have 100 MHz and 200 MHz bandwidths with
maximum real-time sample rates of 1 GSa/s and 2 GSa/s respectively.
With its 5.7-inch LCD color display, the U1610/20A oscilloscope is capable of
clearly distinguishing waveforms from two channels. The U1610/20A allows you
to perform up to 30 types of automatic measurements. Waveform math and Fast
Fourier Transform (FFT) functions are available for performing quick waveform
analyses in both time and frequency domains.
The U1610/20A can also function as a digital multimeter (DMM) and a data
logger. The autorange function provided allows you to perform quick and
accurate DMM measurements. Using the data logger function, you can perform
automatic data logging for DMM and scope measurements.

Charge the Battery
NOTE
Unplug the power adapter when measuring signals to improve the common
mode rejection.
Before using the handheld scope for the first time or after a prolonged storage
period, fully charge the battery for at least 3 hours, with the handheld scope
turned off, using the AC/DC adapter provided. If the battery is fully discharged
after subsequent use, charge the battery with the handheld scope turned on.
The power key will turn constant yellow when the battery is fully charged.

Perform Self-Calibration
WARNING
When performing self-calibration, no signal is injected into the handheld scope.
During the self-calibration process, the firmware will perform zero, offset, and
TDC calibration.
– For zero calibration, the firmware will acquire samples for a fixed period of time
corresponding to the zero input condition. The acquired data contains channel
noise and DC offset. The firmware determines this channel DC offset and upon
completion of self-calibration, uses the determined DC offset to subtract from
ADC samples, producing offset-compensated samples. This feature is useful
for removing channel DC offset due to temperature changes and component
aging, thus providing better accuracy.
–Offset calibration (performed after completion of the zero calibration)
calibrates the system offset DAC for gain accuracy. During calibration, the
firmware determines the offset DAC code settings required to offset the zero
input signal trace to +4 divisions and –4 divisions (vertical). The codeword
range for the offset DAC to move the zero input trace across ±4 division range
will represent the offset DAC gain. This gain changes due to temperature
variation and component aging. Offset calibration corrects for this drift in the
offset DAC gain.
– TDC calibration calibrates and corrects for errors (due to temperature
variation) in the time interval measurement performed by the TDC circuit.
Allow the handheld scope to warm up for at least 30 minutes before performing
self-calibration. It is recommended that you perform self-calibration in the
following situations:
Getting Started 1
Keysight U1610/20A User’s Guide 25
– Every 12 months or after 2000 hours of operation.
– If the ambient temperature is >10 °C from the calibration temperature.
– To maximize the measurement accuracy.
– After experiencing abnormal operation.
– To verify proper operation after repairing.
Disconnect all probe and meter connections to the input terminals of the
handheld scope before performing self-calibration.

BNC adapter
Compensate the Scope Probe
Perform scope probe compensation whenever you attach a passive scope probe
to any input channel for the first time. This is important to match the probe
characteristic to the handheld scope. A poorly compensated probe can introduce
significant measurement errors.
To adjust the probe compensation for a channel:
1 Connect the passive probe to the channel terminal and the probe contact to
the external trigger terminal using a BNC adapter as shown below.
2 Press , then toggle to turn on the compensation signal for
a channel.
3 Press repeatedly to set the probe attenuation factor.
4 The input signal is 5 Vpp, 1 kHz from the external trigger.
Use a nonmetallic tool to adjust the trimmer capacitor on the probe for the flattest
pulse possible.
