TEKTRONIX 468, 100 MHz, DUAL TRACE ANALOG/DIGITAL STORAGE OSCILLOSCOPE CALIBRATED -- WARRANTEED Tektronix 468, 100 MHz, dual channel portable oscilloscope with digital storage capability. The 468 is truly the Cadillac of the famous Tektronix 4XX series of oscilloscopes. It features all the flexibility and features of the famous 465B as well as the capability to digitize and display a complex waveform with a 10 MHz digitizing bandpass. The 468 is unique in the famous 4XX series of oscilloscopes in that is has all the flexibility of an analog instrument along with the very useful dual channel digital storage feature. The 468 can be switched between analog and digital modes with the press of a button. The 468 is a portable digital storage oscilloscope with a four trace, DC to 100 MHz vertical deflection system. The 468 combines an easy-to-use storage function with cursor management of time and voltage. Measurement values are indicated on a four-digit, seven segment digital display. The 468 will operate from 99 to 132 or 198 to 250 VAC, 48 to 440 Hz and at elevations up to 15,000 feet.

If we happen to have a VHS device and it goes bad we immediately think of purchasing a new one rather than repairing the old one. I think this is because the industry advances so rapidly that it does not pay to repair an old VHS device since the cost of a new one, with new features and technology, approximates the repair costs of the old one.Such is certainly not the case with the older Tektronix Oscilloscopes. The 4XX series of Tektronix Oscilloscopes has easily repairable circuits and technology that is as vibrant today as it was the day it was designed almost 20 years ago. The oscilloscopes of the older Tektronix 4XX series are a joy to use . The analog response is around 1 to 3 nS, a figure that deserves respect even by today's rigid standards of performance. The crisp FET and tunnel diode triggering and bright display of these older Oscilloscopes will stand up to the best that are on the market today. Sure, the band pass of some of the newer Tektronix Oscilloscopes exceeds that of the older 4XX Oscilloscopes but, just how often do you encounter a signal over 300 MHz on your test bench that you must view. The older Tektronix Oscilloscopes did not use Large Scale Integrated (LSI) circuits. Almost all the circuits use transistors that are easy to obtain and are in sockets. Most of the transistors used in the Tektronix 4XX Oscilloscopes are available for about a dime each today. Trouble shooting the older Tektronix Oscilloscopes is fairly easy as Tektronix published outstanding manuals that makes trouble shooting a dream. All the circuits are DC coupled so trouble shooting is merely a matter of taking DC readings at critical points and comparing the measurements to the values published in the service manual. The next generation of Tektronix Oscilloscopes after the 4XX series was the 2XXX series. The 2XXX series uses a lot of LSI circuits, notably in the horizontal and vertical outputs. These LSI devices are subject to high power dissipation and do not hold up well. Replacement of these LSI devices is practically out of the question as Tektronix no longer supports the 2XXX series of Oscilloscopes and the supply of Tektronix made replacement parts has pretty well dried up. After the 4XX series was discontinued in the 1990s, Tektronix began building oscilloscopes with many custom VLSICs (Very Large Scale Integrated Circuits), shoddy mechanicals, and overall lower quality. The 4XX series of Tektronix oscilloscopes are the last oscilloscopes that can be fixed by the average electronic technician using readily available, off the shelf components. These oscilloscopes were once fairly common, but are now becoming rare. It will soon be hard to find an American made metal chassis analog oscilloscope of this quality in excellent condition. So if you are considering a quality Oscilloscope with a proven track record of performance I urge you to consider investing in a superior instrument that has many years ago passed the early infant mortality failure rate of modern electronic devices. In over 50 years of working with Tektronix Oscilloscopes I have found them to be the instruments on the market with the best design. All the resistors are power over-rated by at least 100%; voltage ratings on filter capacitors is at least double the voltage applied to them; diode breakdown voltage is usually double the applied voltage. In short, the 4XX series of Oscilloscopes was designed to give many years of faithful service and that service period has yet to expire. FEATURES OVERVIEW Calibrated to Tektronix specifications, power on aged for 100 hours and calibration rechecked Unlimited warranty for 30 days No questions asked return within 5 days of receipt if not delighted. Restrictions apply, please read section on Return Rights. Analog display or Digital Storage display modes available, digital sample rate 10 MHz Signal AVERAGING or ENVELOPE display available in Digital Storage mode Cursor controlled measurement of P-P Volts or Time in Storage Mode 100Mhz Bandwidth ( under 3.5 nS risetime) 20 nS/DIV to .5SEC/DIV calibrated sweep range (2 nS/DIV using 10x sweep multiplier) 5 mV/DIV to 5V/DIV calibrated Vertical Sensitivity Very fast, stable patented FET and tunnel Diode triggering functional to well beyond 100 MHz Very high timing accuracy: under +/-1% on center line even at 20 nS/DIV 1X/10X auto probe detection ALT switching of B trace and display of delayed trace over full 10 DIV LED front panel status indicators A/B Trace Separation Control with Separate B Intensity Control NON-STORE MODE In the NON STORE mode the 468 operates as a conventional 465B oscilloscope that can display CH 1, CH 2, ADD, and A TRIG VIEW (external trigger only) simultaneously. STORAGE MODE The 468 digital storage circuitry has a 10 MHz useful storage bandwidth for the acquisition of signals, and will display the acquired waveform with a bright, flicker-free trace. With the digital storage feature, low-frequency signal analysis and waveform measurements, previously difficult or impossible to make with conventional oscilloscopes, are easily performed. The STORAGE MODE features NORMAL, ENVELOPE, AVERAGE, SAVE and SAVE REFERENCE modes of operation. In the NORMAL MODE the input waveform is digitized using 512 samples for the full 10 horizontal DIVISIONS. In the ENVELOPE MODE the digitized waveform is displayed as an overlap where the previous waveform is not erased from the display. In the AVERAGE mode the incoming waveform is averaged over a preselected number of counts in powers of 2 from 2 to 512. In the SAVE MODE the digitized waveform is preserved in memory. In the SAVE REFERENCE MODE the saved waveform may be displayed in it's original form when the HORIZONTAL TIME/DIV knob is rotated. A STORAGE WINDOW pushbutton allows selection of PRE or POST trigerring from the input waveform. The DISPLAY RESPONSE pushbutton allows selection of the response characteristics of the digitizing circuitry, either SINE or PULSE. The duration (TIME) and amplitude (VOLTS) of the digitized waveform may be measured using two movable cursors for amplitude and two movable bright points for duration. The CURSOR/NUMBER OF SWEEPS control selects the position of the cursors, the bright dots for time and the number of AVERAGING or ENVELOPE sweep to display. VERTICAL The 468 features dual calibrated vertical amplifiers each with deflection factors from 5 mV/DIV to 5 V/DIV in 10 steps of 1-2-5 sequence. The bandpass of each channel is DC to well over 100 MHz. The two traces may be viewed independently using either ALT or CHOP (alternate or chopped) switching; or algebracially added together. A separate switch is used to change the polarity of CHANNEL 2 so the oscilloscope may be operated differentially in the ADD vertical mode. HORIZONTAL The horizontal deflection system consists of two sweep circuits. These are the MAIN and the DELAYED sweeps. Both sweeps feature calibrated sweep speeds from 20 nS/DIV to .5 S/DIV in 23 calibrated steps also of 1-2-5 sequence. The B or DELAYED sweep may be used alone, used to intensify portions of the A or MAIN trace or be used to sweep at the B rate after an amount of time set on the DELAY TIME POSITION control. TRIGGERING The 468 features the famous rock steady FET and tunnel diode triggering used on all the higher priced Tektronix oscilloscopes. This oscilloscope will trigger faithfully from DC to well over 100 MHz on vertical deflections as small as 0.4 DIV. Each sweep, A and B, have independent trigger controls variable over the complete span of the vertical display waveform. DELAYED SWEEP The DELAYED or B sweep uses the ALT feature where the first few divisions, determined by the setting of the DELAY TIME POSITION control, are swept at the A rate and the intensified portion of the A trace is swept out over the full 10 DIV on a separate trace which may be positioned by the operator to be above or below the original A trace. DISPLAY The display shows two waveforms. Each is the 5 second marker from a Tektronix type 184 Time Mark Generator. As you will observe, the upper trace looks pretty normal. The upper trace is the 5 Second marker swept at 20 mS/DIV and .5 V/DIV. This waveform has been digitized and stored. The vertical position was then moved down to where the lower trace is and single trace triggered at 2 uS/DIV, and still at .5V/DIV. Note the spike preceeding the now gradual risetime, this is a defective marker. The 10% to 10% pulse width on the spike is highlighted using the TIME measuring feature built into the 468 and the seven segment display shows 1.38 uS as the width of the spike. This measurement would be impossible to make using any other type of oscilloscope. Please consider this: you are measuring a pulse of about 1.2V amplitude with a width of 1.38 uS that occurs once every 5 seconds and appears about 6uS before the 4V marker, a measurement that is very difficult at best. Also please note, there are no input cables to the oscilloscope, both digitized waveforms are stored in the internal memory. CALIBRATION AND AGING This oscilloscope has been thoroughly and meticulously cleaned inside and out, a new air filter is installed then the oscilloscope undergoes a complete performance check as specified in the Tektronix service manual then finally calibrated to within Tektronix specifications using NIST traceable Tektronix calibration equipment. This oscilloscope is then powered on for a minimum of 100 hours (5 days straight) at the end of which time the calibration is rechecked again to Tektronix specifications. This aging process is performed to insure the buyer that this oscilloscope will be stable and reliable. WARRANTY This fine oscilloscope carries an unlimited 30 day warranty after receipt by the buyer providing the calibration sticker has not been tampered with. RETURN RIGHTS This oscilloscope carries a no-questions asked 5 day after receipt return policy providing the buyer agrees to pay all expenses and that the calibration sticker is intact. Since the oscilloscope will be out of my hands for an extended period of time I would not feel comfortable reselling this instrument without re-calibrating it. Therefore, before accepting any returned oscilloscope back for a refund I would have to charge the original buyer the $225 recalibration fee. A refund check, minus shipping, handling and recalibrating fees, will be issued within five days to the original purchaser only. PACKING AND SHIPPING Buyer agreees to pay a professional packing fee of $17 and actual shipping cost to destination. USPS Priority is the preferred shipping media for shipments in the CONUS but, I would be happy to ship DHL for overseas, UPS or FedEx, buyers choice. I will also ship on your account or, you can snail mail me a preapid shipping label. E-Mailing a prepaid shipping label does not work as the shipper cannot always read the scan code.
