2400B Series PortableAnalog Oscilloscopes

Now your top choice in portable analogscopes is more automatic than ever .The Tek 2400B Series combines new con-venience and leading-edge performance,now up to 400 MHz. Six scopes bring un-precedented efficiency to your design lab,production line or field service site .Measure signals on screen In less time-automatically.You can measure rise time, fall time, fre-quency, width, voltage and time intervalA to B on A sweep at the push of a but-ton. In addition, setup and measurementfunctions can be initiated by pressing anII) button on the head of Tek's new P6137passive voltage probe.The 2400B Series features Auto Setup-a tremendous time-saver. Just attach upto four probes to signal points, pressAUTO SETUP, and within seconds youhave a stable, automatically triggereddisplay of your probed waveforms. Itcouldn't be simpler.Auto Setup includes Tek's proprietaryPulse Mode for viewing narrow pulses indetail . Your scope calculates the duty fac-tor and properly displays either the low-duty-cycle pulse or several cycles of sym-metrical waveforms. The scope willdisplay, position and scale up to fourwaveforms.

Instant access to complex setups meanseven faster measurements.For closer examination of your signals andfor specialized setups-such as delayedsweep displays or displays using the ex-tended measurement options-front-panel control manipulations are stillnecessary. But now you need to createcomplex setups only once.Non-volatile memory for 30 setups storesall front-panel information, includingtrace and readout intensity, cursor loca-tions and control settings for themeasurement options. Each setup can belabeled with a descriptive name fornatural association and ease of recall .This is a fast, easy alternative to the pro-cess of re-creating a front-panel setupevery time you want to change measure-ments. Your attention can be focused on

Four waveforms were triggered, scaled andpositioned by simply pressing AUTO No otheradjustments were necessary

problem-solving, not control adjustments .For example, by simply recalling previous-ly saved setups, design engineers candisplay and make measurements on wide-ly varying waveforms for purposes suchas verifying products, demonstrating pro-totype behavior, generating documenta-tion and characterizing devices, allwithout having to repeat time-consum-ing, manual front-panel setups.Field service personnel can preset fre-quently used test setups and operatemore effectively in much less time.Automate measurement sequenceswithout an external controller .You can also set up, store and sequenceyour systematic verification proceduresfor engineering prototypes, final produc-tion test or field service without acomputer-and without writing a single

Visual writing speed combined with thehigh display update rate of the 2467B pro-vides the quick response and high visibili-ty necessary to see faults in today's com-plex, high speed systems.Observe faults you couldn't see before.The 2467B with microchannel-plate(MCP) CRT instantly reveals events otherscopes fail to show . At 4 cm/ns, its visualwriting speed is approximately 100 timesfaster than that of any other portable in-strument. This makes it possible to see andidentify circuit faults caused by erratic orinfrequent events that may occur only oncein a million normal cycles. Plus, these faultscan be seen in normal room light, withouta viewing hood .Tek's exclusive microchannel-plate CAT.Tek's unique MCP display amplifies theintensity of infrequent signals, yet limitsthe intensity of signals with high-repetition rates. This results in visualwriting speed sufficient to display every-thing that happens in your circuit,whether it occurs once or repetitively .The 2467B displays glitches that remainhidden on scopes with conventional CRTs,and that digital storage scopes fail to cap-ture because of low trigger probability .Being able to see unexpected transients,even within highly repetitive events,makes the critical difference in manytroubleshooting situations.

4 ns/div Visual Writing Speed

4 ns/div visual writing speed-the advan-tage is visible!Writing speed has traditionally been ameasure of CRT performance. However,the performance of conventional CRTs isusually specified as photographic writingspeed and represents the point at whichphosphor luminance is adequate torecord a waveform using a camera andhigh-speed film-but still invisible to theeye.On the other hand, specifying visual

iwriting speed identifies a scope as beingable to emit enough light to be visible tothe eye in normal room light without aviewing hood .The Tek 2467B specifies CRT visualwriting speed at 4 cm/ns Most important,its single-shot and system bandwidths arethe same, 400 MHz . For the first time witha portable instrument you can use all ofits bandwidth in single-shot applications .

The visual writing speed of conventionalanalog scopes is inadequate to permitfull-bandwidth, single-shot use .

The 8467Eand Tek DCS01 Digitizing Camera System combine to give you 400 MHz single-shotcapability along with up to 10 ps/point digitizing.

Digital design and test engineers, for ex-ample, now have an effective and afford-able tool for identifying system faultscaused by troublesome design bugs suchas asynchronous noise, crosstalk, bus con-tention, marginal timing, metastability ora one-in-a-million anomaly. This helpsshorten product design cycles-anddeliver more reliable products .Digitize, store and analyze waveforms onyour IBM PC.The Tektronix DCS01 (Digitizing CameraSystem) bridges the gap between youranalog scope and PC. It easily and cost-effectively adds digitizing and signal pro-cessing capability to the 2467B . Thescope's microchannel-plate CRT allowsthe capture of transient and repetitivesignals at the full 400 MHz bandwidthwith 8-bit resolution (12 bits on repetitivesignals) .Add Tek Signal Processing and Display(SPD) software for 186 waveform analysisfunctions. Both DCS and SPD softwareare modular for solutions satisfying yourunique requirements.For additional information on DCS soft-ware see the Digitizer section . For SPDrefer to the Test and Measurement Soft-ware section .Find circuit problems in digital systems .When troubleshooting a digital system,you want to see a fault immediately .When using a logic analyzer for digitaltroubleshooting, the perfect companionis the Tek 2467B. With the 2467B's highvisual writing rate, digital glitches suchas runt pulses and metastability are readi-ly viewed-as they happen .Due to short trigger holdoff and sweepreset times, the display update rate ofanalog scopes such as the 2467B is muchhigher than digital storage oscilloscopes.This plus Tek's exclusive MCP-enhancedCRT makes it possible for the 2467B todisplay intermittent variations as theyhappen, even if masked by thousands ofnormal traces.

The metastability in this high-repetition rateflip-flop output occurs only once in a millionnormal cycles, yet it is clearly visible thanksto the 2467B's high visual writing speed

Other instruments may not display theseinfrequent faults at all or may takeseveral minutes to build up a display thatshows an occasional fault .With 30 ns pretrigger display, you can ex-amine the inputs to a logic device priorto the output transition . Seeing the inputswhen a fault occurs can point to the realproblem .To see marginal amplitude signals thatmight otherwise go undetected, set thetrigger level just above the low logic levelor just below the high logic level . Trigger-level readout lets you set the trigger pointwhere you want it, without trial anderror.Determine actual noise margins.With its ability to clearly display transientevents in the presence of numerous nor-mal signals, the 2467B shows designersactual noise margins essential for reliablesystem operation . With the 2467B, nomatter how infrequently noise pulses oc-cur, they are clearly displayed . You cansee the worst case even if it is asyn-chronous to the monitored signal .

Cursors are set to indicate input thresholdlimits. The high visual writing speed of the2467B easily shows this infrequent glitch nar-rowly missing the upper threshold limit .

Measure worst-case setup and holdtimes .Digital systems rely on valid setup andhold times. Noise, timing changes invarious system states, and power-supplycoupling-all can cause infrequent timingviolations.The 2467B lets you see timing changesimmediately, because the short dead timebetween sweeps gives a high probabilityof displaying occasional changes in high-repetition rate signals. Other instrumentsmay require long periods to construct adisplay, if they can show the variationsat all .

In this display the data (upper trace) occa-sionally moves into coincidence with the ris-ing edge of the clock (lower trace), violatingthe timing margin. Also note the occasionalchange in clock pulse width .
