Because the TDSB oscilloscope can stop acquisition, sound a beep, make a hard copy or save the waveform when it detects an anomaly, you can run tests over long time periods - even unattended - to find those challenging, very infrequent failures.
This seamless integration extends the power and value of these brilliantly engineered, affordable oscilloscopes. View Cart My Account Please Call. Add to cart. Make Offer. Very Nice. DPOs are far less likely to have blind periods due to excessively one-sided resource allocation or inability to multi-task. BTW, analog scopes also have "blind" periods briefly during sweep retrace, and variably during "holdoff", if you choose it.

Do not operate this product with covers or panels removed. Avoid Exposed Circuitry. Do not touch exposed connections and components when power is present.
If you suspect there is damage to this product, have it inspected by qualified service personnel. Provide Proper Ventilation. Safety Terms and Symbols Terms in this Manual. These terms may appear in this manual:. Warning statements identify conditions or practices that could result in injury or loss of life.
Caution statements identify conditions or practices that could result in damage to this product or other property. Electrostatic discharge ESD can damage components in the oscilloscope and its accessories.
To prevent ESD, observe these precautions when directed to do so. Use a Ground Strap. Wear a grounded antistatic wrist strap to discharge the static voltage from your body while installing or removing sensitive components. Use a Safe Work Area.
Do not use any devices capable of generating or holding a static charge in the work area where you install or remove sensitive components. Avoid handling sensitive components in areas that have a floor or benchtop surface capable of generating a static charge. Handle Components Carefully. Do not slide sensitive components over any surface. Do not touch exposed connector pins.
Handle sensitive components as little as possible. Transport and Store Carefully. Transport and store sensitive components in a static-protected bag or container. Product End-of-Life Observe the following guidelines when recycling an instrument or component:. Mercury Notification. This oscilloscope uses an LCD backlight lamp that contains mercury. Disposal may be regulated due to environmental considerations. Please contact your local authorities or the Electronics Industries Alliance www.
Battery Recycling. This product may contain a Nickel Cadmium NiCd or lithium ion Li-ion rechargeable battery, which must be recycled or disposed of properly. Please properly dispose or recycle the battery according to local government regulations. Consult your air carrier for applicability and determination of any special lithium ion battery transportation requirements.
Only qualified personnel should perform service procedures. Do Not Service Alone. Do not perform internal service or adjustments of this product unless another person capable of rendering first aid and resuscitation is present. Disconnect Power. To avoid electric shock, switch off the instrument power, then disconnect the power cord from the mains power. Dangerous voltages or currents may exist in this product. Disconnect power, remove battery if applicable , and disconnect test leads before removing protective panels, soldering, or replacing components.
This Service manual provides information to troubleshoot, disassemble, and repair the following TDSB Series Digital Phosphor Oscilloscopes instrument to the module level:. After office hours, please leave a voice mail message. Outside North America, contact a Tektronix sales office or distributor; see the Tektronix web site for a list of offices. Specifications that are marked with the n symbol are checked in Performance Verification.
H The oscilloscope must have been operating continuously for twenty minutes within the operating temperature range specified. H You must perform the Compensate Signal Path operation described on page prior to evaluating specifications. Operating: 0. Nonoperating: 2. High quality shielded cables typically are braid and foil types that have low impedance connections to shielded connectors at both ends. Ambient conducted fields may induce triggering when the trigger threshold is offset less than 4 major divisions from ground reference.
Ambient conducted fields may induce triggering when the trigger threshold is offset less than 1 major division from ground reference. H Connecting power and using the battery pack. H Installing an application module.
H Installing a communication module. H Front-panel menus and controls. H Frontand rear-panel connectors. H Transporting the oscilloscope. For information about unpacking and inspecting the instrument, see Unpacking and Repacking Instructions on page of this manual. Open the strain relief clip and slip it onto the power cord. Snap the strain relief into its hole in the rear panel of the oscilloscope.
Connect the power cord to the power input connector. The oscilloscope is grounded through the power cord. The line fuse is internal and is not user replaceable. A triangle icon in the display shows when the battery is in use, a power-plug icon shows when line power is connected, and a gauge icon shows the relative charge level in the battery.
The oscilloscope turns off automatically when the battery runs low. Refer to the General Safety Summary for information about proper rechargeable battery disposal. To avoid electric shock, always connect the rear-panel ground terminal to earth ground when operating the instrument from battery power.
For safe operation, the oscilloscope chassis must remain at earth ground potential even when operating from battery power. To protect against this condition, attach the Tektronix-supplied grounding wire from the terminal on the rear panel to earth ground. If you use a different grounding wire, it must be larger than 18 gauge 1 mm 2. When you start to use the battery pack, an on-screen message reminds you to connect the grounding wire between the ground terminal on the rear panel and earth ground.
Installing and Removing To install the optional battery pack, do these steps: the Battery. Open the battery compartment door on the rear panel and remove the accessory tray.
