Tektronix TLS 216 Logic Scope

Section 2 Operating Basics covers basic principles of the operation of the logic scope. The topics covered help you understand why your logic scope operates the way it does.

Section 3 Reference teaches you how to perform specific tasks. See page 3-1 for a complete lists of tasks covered in that section.

The Appendices provide an options listing, and accessories listing, and other useful information.

Programmer Manual

This programmer manual covers the TLS 216 Logic Scope. It provides information on operating your logic scope using General Purpose Interface Bus (GPIB) interface.

Section 1 Getting Started describes how to connect the logic scope to a controller.

Section 2 Syntax and Commands describes the structure and content of the messages your program sends to the logic scope. Section 2 also describes what each command does and provides examples of how you might use them. The subsection Command Groups lists commands by functional area. Command Descriptions describes the commands in alphabetical order.

Section 3 Status and Events describes how to use service requests (SRQ's) and various event messages in your programs. This section also lists the status and error messages the logic scope provides.

Section 4 Programming Examples describes some example logic scope programs and how to compile them. The 3.5" and 5.25" disks that come with this manual contain an executable Microsoft QuickC 2.5 source code version of each program.

Display

Mixed-mode Data Display: Logic Scope offers Analog, Timing, and BusFormTM display formats that simplify recognition of digital timing faults and signal anomalies. BusFormTM display compresses many input signals into the least amount of display area. The acquired data can be displayed in any of the three display modes without re-acquiring.

Waveform collision areas highlighted with different color. Statistical waveform distribution shown with color grading through variable persistence.
Color Grading: With variable persistence selected, historical timing information is represented by temperature or spectral color scheme providing "z-axis" information about rapidly changing waveforms.

AUX Trigger Input: TTL compatible; Max input voltage is -1 V to +6 V.

Measurement System

The Logic Scope provides a comprehensive suite of automatic measurements specifically designed to improve efficiency when troubleshooting digital hardware. Twenty-eight on-board measurements, including setup time, hold time, and skew, speed identification of common digital problems. Whereas traditional DSOs confine waveform measurements to establishing the relationship of a single channel to a clock, the Logic Scope simultaneously samples on all channels, so you can see the relationships between multiple channels.
Automatic Waveform Measurements: Period, Frequency, High, Low, + Width, - Width, Maximum, Minimum, Rise, Fall, Peak to Peak, Amplitude, + Duty Cycle, - Duty Cycle, + Overshoot, - Overshoot, Propagation Delay, Burst Width, Mean, Cycle Mean, RMS, Cycle RMS, Area, Cycle Area, Phase, Setup Time, Hold Time, Skew.

Trigger Types (Main And Delayed)

Edge: Trigger when either a rising or falling edge (positive or negative slope) is detected.
Pulse: The pulse may be positive or negative and defined by a duration.
Width (<Time, >Time): Trigger when the duration of either a positive or negative pulse is less than or greater than the user-defined input.
Range (In Range, Out of Range): Trigger when the duration of either a positive or negative pulse is either between the upper and lower limits or outside the limits.
Time-out: Trigger at the end of a user-defined time period if the trailing edge of either a positive or negative pulse is not detected.
Pattern: Each input may be defined as a low (logic 0), high (logic 1), or don't care (X). Inputs can be ANDed or ORed. The pattern may be positive true or positive false.
Width (<Time, >Time): Trigger when the duration of a user-defined logical pattern is less than or greater than the user-defined input.
Range (In Range, Out of Range): Trigger when the duration of a user-defined logical pattern is either between the upper and lower limits or outside the limits.
Time-out: Trigger at the end of a user-defined time period if the user-defined logical pattern of a specified duration does not occur.
Sequence: The sequence is defined by a set of start and end events. The start or end event can be either a pattern or an edge (positive or negative slope).
Width (<Time, >Time): Trigger when the duration between the user-defined start and end events is less than or greater than the user-defined input.
Range (In Range, Out of Range): Trigger when the duration between the user-defined start and end events is either between the upper and lower limits or outside the limits.
Time-out: Trigger at the end of a user-defined time period if the user-defined end event does not occur within the specified time after the start event.
