Tektronix THS720A, 2-channel 100MHz Digital Oscilloscope (Scope/DMM)

Description: Listing is for Tektronix THS720A oscilloscope complete with AC power supply, a rechargeable battery pack for stand alone operation, The physical condition is fair, with the exception of an area to the right of the display where a label had been bonded to the case with epoxy. All start up and self tests are passed for both the scope and DMM feature. Specifications for this oscilloscope are given below. The scope comes with a Tektronix rechargable battery pack that does hold a charge and operates the scope. This listing is for the THS720A and an AC power supply that operates the scope from 120 V Mains, and serves as a charger for the battery pack. It does not include Scope Probes, or Meter Leads.

Physical CharacteristicsWidth: 177 mmHeight: 217 mmDepth: 51 mmWeight: Net 1.45 kgDescription of Photos: All Photo's taken after a 20 minute warmup period. Photo - 1 - Shows display of sine wave from external generator on both channels. Photo - 2 - Triangular waveform displayed on both channels. Photo - 3 - Shows Start Up test are passed. Scope restarted after a 20 minute warmup. Photo - 4 - Shows a Square Wave displayed on both channels. Photo - 5 - Measurement of the Rise time of the leading edge of the Square Wave displayed in photo 4. Note the display of the RT of the waveform on channel 1 at the right edge of the screen C1 Rise = 15.5 nsec. Horizontal setting is 50 nsec/ div. Photo - 6 - Photo showing the measurement of a low level (20 mVolt) sinewave. Note the pk-pk measurement at the right edge of the screen (22mVolt). Note the very low level of noise on the displayed waveform. Photo - 7 - Display showing the noise level of both channels with no inputs connected. Note noise level for channel 1 is 3.6 mVolts, and for channel 2 is 4.8 mVolts. Vertical setting is 5 mVolts/div for both channels. Photo - 8 - Measurement of a 16.7 KOhm 2% resistor using the Meter Mode of the instrument. Photo - 9 - Measurement of a AAA cell using the Meter Mode. Photo - 10 - Photo showing that all Calibration procedures have passed, including Signal Path Compensation (SPC). Photo - 11 - Photo showing the operation of the Scope with battery power (Note the plug has been disconnected at the top of the screen). The battery pack in this scope is a Tektronix manufactured pack. It does not appear to be the original pack, but I do not know when it was added as there is no manufacturing date on the pack. It charges and holds a charge, but I do not know how long it operate the scope when fully charged. Photo - 12 - Front view of the scope with no power applied. Note the buttons and keys are all operational with clear lettering. Also note the area at the right side of the display where the serial number label was attached using epoxy. The label has been removed, but the epoxy is a 'permanent feature'! Photo - 13 - Photo showing the Right Side of the ScopeMeter. Note the inputs for the DMM feature. Photo - 14 - Left side view of scope. The cloth carrying handle is operational and in good shape. Photo - 15 - Top view, scope input ports. Note battery access door at the Right. Photo - 16 - Showing the back of the scope with the Stand in the open position, showing the label. Photo - 17 - Back of scope with the Stand in the Stowed position. *This listing is for the THS720A with battery pack and AC power supply/charger only. No test leads are provided as part of this listing. Any standard scope probe and meter test leads will work.
