The HP 1660-SeriesBenchtop Logic Analyzers

Product Specificationsand Characteristics

Technical Data

Finding the cause of difficult problems fast.There is little room for error in the schedules for design projectstoday. You need test equipment thatcan locate the cause of a problemquickly and with certainty.

The HP 1660-series logic analyzershelp you rapidly troubleshoot elusive hardware failures, verifyproper bus operation, and debugsoftware during real-time execution.

Choose a model with 34, 68, 102 or136 logic analyzer channels. Theyall have enough timing and stateanalysis speed to handle even high-performance applications.Then consider adding a built-in, 2-channel oscilloscope to showsignal parametrics – especiallywhen the logic analyzer locates a failure.

We think you will agree that theselogic analyzers have the right combination of performance, flexibility, and ease of use to helpyou solve difficult problems fast.

HP 1660-SeriesGeneral Product Information

___________________________________________

Human Interface___________________________________________

Front Panel A knob and keypads makeup the front-panel humaninterface. Keys includecontrol, menu, display nav-igation, and alpha-numericentry functions.

___________________________________________

Mouse An HIL, 3-button mouse(HP p/n A2838A) is shippedas standard equipment. Itprovides full instrumentcontrol. Knob functionalityis replicated by holdingdown the center buttonand moving the mouse leftor right.

___________________________________________

Keyboard The logic analyzer can alsobe operated using an HILkeyboard. Order the HPLogic Analyzer KeyboardKit, model number E2427A.

___________________________________________

Input/Output, Control, and Printing___________________________________________

I/O Ports The HP 1664A ships with aparallel (Centronics) print-er port as standard equip-ment; RS-232 and HP-IBports are optional. All othermodels ship with RS-232and HP-IB as standardequipment but do not havea parallel port.

___________________________________________

Program- Each instrument is fullymability programmable from a com-

puter via HP-IB and RS-232connections. This featureis standard on all modelsexcept the HP 1664A.Order option 020 for HP 1664A programmability.

___________________________________________

___________________________________________

HP Printers which use the Printer HP Printer Control Support Language (PCL) and have

an HP-IB, RS-232 or paral-lel* interface are support-ed: HP DeskJet, LaserJet,QuietJet, PaintJet, andThinkJet models.* HP 1664A only

___________________________________________

Alternate The Epson FX80, LX80 and Printer MX80 printers with anSupported RS-232 interface are

supported in the Epson 8-bit graphics mode.

___________________________________________

Hard Copy Screen images can be Output printed in black and white

from all menus using thePrint field. State or timinglistings can be also beprinted in full or part (start-ing from center screen)using the Print All selection.

___________________________________________

Mass Storage Files and Software___________________________________________

Updating the For models other than the Operating HP 1664A, the operating System system resides in Flash

ROM and can be updatedfrom the flexible disk drive.The HP 1664A boots fromdisk and requires only adisk change to update theoperating system.

___________________________________________

Mass Storage A high density (1.44-Mbyte), 3.5" flexible diskdrive supports LIF and DOSformats.

___________________________________________

Screen Image An image file of any display Files screen can be stored to

disk via the display's Printfield. Black & white TIFF,PCX, PostScript, and gray-scale TIFF file for-mats are available.

___________________________________________

___________________________________________

ASCII Data State or timing listingsFiles can be stored as ASCII files

on a flexible disk via the dis-play's Print field. These filesare equivalent in characterwidth and line length to hard-copy listings printed via thePrint All selection.

___________________________________________

Configuration Logic analyzer and oscillo-and Data scope files that includeFiles configuration and data infor-

mation (if present) are encod-ed in a binary format. Theycan be stored to or loadedfrom a flexible disk.

___________________________________________

Recording of Binary format Acquisition and configuration/data files areStorage Times stored with the time of

acquisition and the time ofstorage for all models exceptthe HP 1664A, which does nothave a real-time clock.

___________________________________________

Acquisition Arming___________________________________________

Initiation Arming is started by Run,Group Run, or the Port InBNC.

___________________________________________

Cross Arming Analyzer machines and the oscilloscope can cross-arm each other.

___________________________________________

Output An output signal is provid-ed at the Port Out BNC.

___________________________________________

Port In/Out___________________________________________

PORT IN Port In is a standard BNC Signal and connection. The input Connection operates at TTL logic

signal levels. Rising edgesare valid input signals.

___________________________________________

PORT OUT Port Out is a standard BNCSignal and connection with TTL logic Connection signal levels. A rising edge

is asserted as a valid output.___________________________________________

Skew Adjustmentand Arming Times___________________________________________

Skew Correction factors for Adjustment nominal skew between

displayed timing and oscil-loscope signals are builtinto the operating system.Additional correction forunit-by-unit variation canbe made using the Skewfield. An entered skewvalue affects the next (notthe present) acquisitiondisplay.
