In your system or onthe bench, the 3458A saves you timeand money with unprecedented testsystem throughput and accuracy,seven function measurementflexibility, and low cost of ownership.Select a reading rate of 100,000readings/second for maximal testthroughput. Or achieve highest levelsof precision with up to 8.5 digits ofmeasurement resolution and 0.1 partper million transfer accuracy. Add tothis, programming compatibilitythrough the Agilent MultimeterLanguage (ML) and the 3458Assimplicity of operation and you havethe ideal multimeter for your mostdemanding applications.ContentsTest System Throughput / 6Calibration Lab Precision / 7High Resolution Digitizing /8Technical Specifications / 9Section 1: DC Voltage / 10Section 2: Resistance / 11Section 3: DC Current / 13Section 4: AC Voltage / 14Section 5: AC Current / 19Section 6: Frequency/Period / 20Section 7: Digitizing / 21Section 8: System Specifications / 23Section 9: Ratio / 24Section 10: Math Functions / 24Section 11: General Specifications / 25Section 12: Ordering Information / 26 5. 5The 3458A Multimeter for:High test system throughputCalibration lab precisionHigh resolution digitizingFaster testing Up to 100,000 readings/sec Internal test setups > 340/sec Programmable integration times from500 ns to 1 secGreater test yield More accuracy for tighter test margins Up to 8.5 digits resolutionLonger up-time Two-source (10 V,10 k) calibration,including ac Self-adjusting, self-verifying auto-calibrationfor all functions and ranges,including acSuperb transfer measurements 8.5 digits resolution 0.1 ppm dc volts linearity 0.1 ppm dc volts transfer capability 0.01 ppm rms internal noiseExtraordinary accuracy 0.6 ppm for 24 hours in dc volts 2.2 ppm for 24 hours in ohms 100 ppm mid-band ac volts 8 ppm (4 ppm optional) per year voltagereference stabilityGreater waveform resolution and accuracy 16 to 24 bits resolution 100,000 to 0.2 samples/sec 12 MHz bandwidth Timing resolution to 10 ns Less than 100 ps time jitter Over 75,000 reading internal memory 6. The Agilent 3458A System Multimeterheightens test performance in threephases of your production test:faster test system start-up, faster testthroughput, and lower cost of owner-ship6through longer system uptime,designed-in reliability, and fast andeasy calibration.Faster system start-upThe value of a fast system multimeterin production test is clear. But it isalso important that the dmm programseasily to reduce the learning time fornew system applications. The AgilentMultimeter Language (ML) offers astandard set of commands for themultimeter user that consists of easilyunderstood, readable commands.Easier programming and clearerdocumentation reduce systemdevelopment time.Faster measurements and setupsNow you can have a system dmmwith both fast and accurate measure-ments.The 3458A optimizes yourmeasurements for the right combi-nationof accuracy, resolution, andspeed. The 3458A Multimeter fitsyour needs from 4.5 digit dc voltsmeasurements at 100,000/second,to 8.5 digit dc volts measurements at6/second, or anywhere in between in100 ns steps.Even the traditionally slower measure-mentfunctions, such as ac volts, arequicker with the 3458A. For example,you can measure true rms acV at upto 50 readings/second with fullaccuracy for input frequencies greaterthan 10 kHz.Besides high reading rates, the3458As design was tuned for themany function and level changesrequired in testing your device. The3458A can change function andrange, take a measurement, andoutput the result at 340/second.This is at least 5 times faster thanother dmms. In addition, the 3458Atransfers high speed measurementdata over GPIB or into and out of its75,000 reading memory at 100,000readings/second.You can reduce your data transferoverhead by using the unique non-volatileprogram memory of the 3458Ato store complete measurementsequences. These test sequences canbe programmed and initiated from thefront panel for stand-alone operationwithout a controller.Finally, the 3458A Multimeter makesfast and accurate measurements.Consider the 3458As 0.6 ppm 24 hourdc volts accuracy, 100 ppm ac voltsaccuracy and its standard functionsof dcV, acV, dcI, acI, ohms, frequencyand period. Greater measurementaccuracy from your dmm means higherconfidence and higher test yields.More functions mean greater versatilityand lower-cost test systems.Longer system up-timeThe 3458A Multimeter performs acomplete self-calibration of all func-tions,including ac, using high stabil-ityinternal standards. This self- orauto-calibration eliminates measure-menterrors due to time drift andtemperature changes in your rack oron your bench for superior accuracy.When its time for periodic calibrationto external standards, simply con-necta precision 10 Vdc source anda precision 10 k resistor. All rangesand functions, including ac, are auto-maticallycalibrated using precisioninternal ratio transfer measurementsrelative to the external standards.The 3458As reliability is a productof Agilents 10X program of defectreduction. Through extensive envi-ronmental,abuse, and stress testingduring the design stages of productdevelopment, has reduced the num-berof defects and early failures in itsinstruments by a factor of ten overthe past ten years. Our confidencein the 3458As reliability is reflectedin the low cost of the option foradditional years of return-to-repair.For High Test System Throughput Faster system start-upMultimeter Language (ML) compatible Faster measurements and setups100,000 readings/sec in 4.5 digits50,000 readings/sec in 5.5 digits340 function or range changes/sec Longer system up-timeMultimeter Language (ML) compatible 7. 7In the calibration lab, youll find the3458As 8.5 digits to have extraordi-narylinearity, low internal noise, andexcellent short term stability. Thelinearity of the 3458As Multislope Ato D converter has been characterizedwith state-of-the-art precision. UsingJosephsen Junction Array intrinsicstandards, linearity has been mea-suredwithin 0.05 ppm of 10 volts.The 3458As transfer accuracy for10 volts dc is 0.1 ppm over 1 hour 0.5 C. Internal noise has beenreduced to less than 0.01 ppm rmsyielding 8.5 digits of usable resolution.So, the right choice for your calibrationstandard dmm is the 3458A.dcV stabilityThe long term accuracy of the 3458Ais a remarkable 8 ppm per yearmore accurate than many systemdmms are after only a day. Option 002gives you a higher stability voltagereference specified to 4 ppm/year forthe ultimate performance.Reduced-error resistanceThe 3458A doesnt stop with accuratedcV. Similar measurement accuracyis achieved for resistance, acV, andcurrent. You can measure resistancefrom 10 to 1 G with midrangeaccuracy of 2.2 ppm.Finally, the 3458A, like its dmm pre-decessors,offers offset-compensatedohms on the 10 to 100 k rangesto eliminate the errors introduced bysmall series voltage offsets. Usablefor both two- and four-wire ohms, the3458A supplies a current through theunknown resistance, measures thevoltage drop, sets the current to zero,and
