Page 18: Replacing The Battery Pack
Getting Started Replacing the Battery Pack For portable operation, use the rechargeable battery pack. You can replace the battery pack without losing any saved informa- tion. The current setup, saved setups, saved waveforms, and saved data are all stored in nonvolatile memory that does not depend on battery power.
Page 19 Getting Started Battery Life From a full charge, you can operate the TekScope instrument continuously for approximately two hours. You can extend the battery life by using automatic Power Off Time-out or Backlight Time-out. Refer to page 3–56 for a description of these features. The TekScope instrument turns off automatically when the battery runs low.
Page 20: Using External Power
Getting Started Using External Power Using external power from the AC adapter or cigarette lighter adapter has the following advantages: Saves internal battery power for portable operation later Charges internal battery pack Allows extended operation; the Standby Time-out and Backlight Time-out features are automatically disabled when external power is used Maintains floating measurement capability of the oscilloscope...
Page 21: Using The Tilt Stand
Getting Started Using the Tilt Stand A built-in tilt stand folds out and snaps back into place when not in use. For benchtop use, lock the tilt stand in place with the hinged flap. To hang the TekScope instrument over a nail, rotate the tilt stand 180 .
Page 22: Functional Check
Getting Started Functional Check After you install batteries or connect external power, you can perform this quick functional check to verify that your TekScope instrument is operating correctly. 1. Press the ON/OFF button to turn on the TekScope instrument. 2. After a few seconds, you should see a window with the message Power-On self check PASSED.

Page 35: Taking Floating Measurements
Functional Overview Taking Floating Measurements This section covers important issues to consider when taking floating measurements. Architecture is Important For taking floating measurements, the TekScope instrument has an architectural difference from most other oscilloscopes. The channel 1, channel 2, and DMM inputs are isolated from the main chassis and from each other.
Page 36 Functional Overview Many handheld oscilloscope/DMM products have the architecture shown below, which shares a common reference for the oscilloscope channels and DMM. With this architecture, all input signals must have the same voltage reference when you take any multi-channel measurements. Oscilloscope channels and DMM must float together.
Page 37 Functional Overview Attach the Reference Leads Correctly If you are using both of the oscilloscope channels, you must attach the probe reference lead for each channel directly to your circuit. These attachments are required because the oscilloscope channels are electrically isolated; they do not share a common chassis connection. Use the shortest possible reference lead with each probe to maintain good signal fidelity.
Page 38: Application Examples
Application Examples This section presents a series of application examples. These simplified examples highlight the features of the TekScope instrument and give you ideas about using it to solve your own test problems. The first two examples demonstrate basic scope and meter operation. The remaining examples provide an overview of applications that cover the following areas: Digital circuit testing...

Page 51: Testing A Switching Transistor Drive Circuit
Application Examples Testing a Switching Transistor Drive Circuit You need to evaluate the gate-drive circuit for a power FET (field-effect transistor) in a switching power supply. The gate-drive timing circuit is referenced to chassis ground. But the gate-drive signal is transformer-coupled to the FET, which is connected to a –300 VDC bus.
Page 52 Application Examples Setup to Test the Transistor Drive Circuit SCOPE CH 1 — — — CH 2 AUTO RANGE You do not have to do anything special to take this difficult measurement. Because of the isolated channels, you can reference the channel 1 probe to chassis ground and the channel 2 probe directly to the –300 VDC bus.

Page 184: Glossary
Glossary /– Rocker The general-purpose rocker button on the front panel that you can use to set parameters. The specific parameter assigned to the /– rocker depends on other selections. AC Coupling A mode that blocks the DC component of a signal but passes the dynamic (AC) component of the signal.
Page 185 Glossary Attenuation The degree the amplitude of a signal is reduced when it passes through an attenuating device such as a probe or attenuator (the ratio of the input measure to the output measure). For example, a 10X probe attenuates, or reduces, the input voltage of a signal by a factor of 10.
Page 186 Glossary Common Lead The meter lead attached to the reference voltage in a measure- ment application. Because of the isolated channels, the meter common lead and the scope reference leads do not have to be connected to the same reference voltage. Continuity A test to verify electrical conductivity from one point to another.
Page 187 Glossary Diode Test A test to verify polarity and measure the forward voltage drop of a semiconductor junction. Display The word used to refer to the screen or the LCD (liquid crystal display). Edge Trigger Triggering that occurs when the oscilloscope detects the source passing through a specified voltage level in a specified direction (the trigger slope).
Page 188 Glossary Holdoff A specified amount of time that must elapse after a trigger signal before the trigger circuit will accept another trigger signal. Holdoff helps ensure a stable display. Horizontal Bar Cursors The two horizontal bars that you position to measure the voltage parameters of a waveform.
Page 189 Glossary Pop-Up Menu A submenu of a menu. Pop-up menus temporarily occupy part of the waveform display area and present choices associated with the menu item selected. You can cycle through the options in a pop-up menu by repeatedly pressing the menu button underneath the pop-up.
Page 190 Glossary Roll Mode An acquisition mode useful at slow horizontal scale settings. Roll mode allows you to view the waveform as it is acquired point-by-point. The waveform appears to roll across the display. RS-232 The serial communication port used to connect to a hard-copy device, computer, controller, or terminal.
Page 191 Glossary Standby (STBY) The off-like state when the instrument in not in use. Some circuits are active even while the instrument is in the standby state. Tek Secure A feature that erases all waveform and setup memory locations (setup memories are replaced with the factory setup). Then it checks each location to verify erasure.
