Safety Notices

CAUTION

A CAUTION notice denotes a hazard. It

calls attention to an operating proce-

dure, practice, or the like that, if not

correctly performed or adhered to,

could result in damage to the product

or loss of important data. Do not pro-

ceed beyond a CAUTION notice until

the indicated conditions are fully

understood and met.

WARNING

A WARNING notice denotes a hazard.

It calls attention to an operating pro-

cedure, practice, or the like that, if

not correctly performed or adhered

to, could result in personal injury or

Additional Safety Notices

This apparatus has been designed and tested in accordance with IEC Publication 1010, Safety

Requirements for Measuring Apparatus, and has been supplied in a safe condition. This is a Safety

Class I instrument (provided with terminal for protective earthing). Before applying power, verify that

the correct safety precautions are taken (see the following warnings). In addition, note the external

markings on the instrument that are described under “Safety Symbols.”

Warnings

• Before turning on the instrument, you must connect the protective earth terminal of the

instrument to the protective conductor of the (mains) power cord. The mains plug shall only be

inserted in a socket outlet provided with a protective earth contact. You must not negate the

protective action by using an extension cord (power cable) without a protective conductor

(grounding). Grounding one conductor of a two-conductor outlet is not sufficient protection.

• Only fuses with the required rated current, voltage, and specified type (normal blow, time delay,

etc.) should be used. Do not use repaired fuses or short-circuited fuseholders. To do so could

cause a shock or fire hazard.

• If you energize this instrument by an auto transformer (for voltage reduction or mains isolation),

the common terminal must be connected to the earth terminal of the power source.

• Whenever it is likely that the ground protection is impaired, you must make the instrument

inoperative and secure it against any unintended operation.

• Service instructions are for trained service personnel. To avoid dangerous electric shock, do not

perform any service unless qualified to do so. Do not attempt internal service or adjustment

unless another person, capable of rendering first aid and resuscitation, is present.

• Do not install substitute parts or perform any unauthorized modification to the instrument.

• Capacitors inside the instrument may retain a charge even if the instrument is disconnected from

its source of supply.

• Do not operate the instrument in the presence of flammable gasses or fumes. Operation of any

electrical instrument in such an environment constitutes a definite safety hazard.

• Do not use the instrument in a manner not specified by the manufacturer.

Safety Symbols

Keysight 16860 Series Logic Analyzer - At a Glance

The Keysight Technologies 16860 series logic analyzers are portable logic analyzers that range from

34 to 136 logic acquisition channels, depending on the model.

The 16860-series models provide features such as:

•deeper memory

•¼ channel 10GHz Timing mode

•deskew of timing traces by individual channels

•single as well as multiple clocks support

•advanced clocking capabilities

•clock hysteresis

•various clock modes such as Master, Dual Sample, Master/Slave, and Demultiplex.

This series of logic analyzers can be used:

•at a higher speed (700MHz to 12.5 MSps) for debug, validation and analysis of DDR and LPDDR

memory systems.

•at a lower speed (350MHz to 0 MSps) as a medium to high performance general purpose logic

analyzer.

Model Comparison

Features, Logic Acquisition

•2 M to 128 M samples of memory depth per channel (depending on memory option), software

upgradeable.

•350 MHz or 700 MHz maximum state clock rate (depending on state speed option), software

upgradeable.

•Full Channel Timing Mode at 2.5 GHz sampling with 12.5 GHz Timing Zoom.

•Half Channel Timing Mode at 5.0 GHz sampling with 12.5 GHz Timing Zoom
