FFT Application Module TDS3FFT (Included)

When this module is installed, the TDS3000B becomes an excellent troubleshooting aid for:

• Testing impulse response of filters and systems
• Measuring harmonic content and distortions in systems
• Identifying and locating noise and interference sources
• Analyzing vibration Analyzing harmonics in 50 and 60 Hz power lines

The TDS3FFT application module provides the following features:

• FFT Windows; Four FFT windows (Rectangular, Hamming, Hanning and Blackman-Harris) let you match the optimum window to the signal you are analyzing
• Analyze repetive, single-shot and stored waveforms: An FFT waveform on any actively-acquired signal, last acquired signal or signal stored in the reference memory can be displayed The FFT vertical graticule can be set to either dB or linear rms
• Time signals and FFT waveforms can be shown on the display at the same time. This helps in the quick analysis of circuit or system problems

Typical Application for the FFT Module
In the design or analysis of power supplies, it is important to check the harmonics in the power supply's load current. The following figure shows the harmonic analysis of a 250 watt class D power supply. Using the scope's cursors, you can measure the frequency and magnitude of the individual frequency components.

Advanced Trigger Module TDS3TRG (Included)

When this module is installed, an advanced trigger menu is added to the TDS3000B with the appropriate logic and pulse triggering capability.

Logic Trigger Features - Logic triggering is extremely useful in the troubleshooting of digital circuits. The oscilloscope is triggered when two signals meet a Boolean trigger condition. This module provides pattern and state logic trigger modes.

Pattern Trigger - Pattern triggering triggers the oscilloscope when two signals become logically true or false. The pattern-triggering feature triggers the oscilloscope from the output of a two-input AND, OR, NAND or NOR logic gate. You can specify time constraints and signal threshold levels as part of the triggering condition. The trigger is useful for digital logic troubleshooting.

State Trigger - State triggering triggers the oscilloscope when a state signal is true or false at the time a clock signal transition is true. This trigger is useful for troubleshooting digital logic synchronous state machines.

Pulse Trigger Features - Provides three pulse trigger modes: Pulse-width (glitch) triggering triggers the oscilloscope when a signalpulse width is les than, greater than, equal to or not equal to a specified pulse width. this trigger is useful for digital logic troubleshooting. Runt-pulse triggering triggers the oscilloscope when a signal pulse is less than a specified threshold level. You can also specify runt pulse-width parameters. This trigger is useful for troubleshotting bus-contention problems. Slew-rate triggering triggers the oscilloscope when a signal's slew rate (rise or fall time) is less than, greater than, equal to or not equal to a specified slew rate. This trigger is useful for troubleshooting digital bus transcievers, transmission lines and op-amp circuits.

The TDS3AAM module adds advanced analysis capability to your TDS3000B. With it you can define waveforms as arbitrary math expressions - including a variety of mathematical functions plus constants and measurements. The TDS3AAM also adds Area and Cycle Area measurements, differentiation and integration functions, measurement averaging, and measurement statistics. Enhanced XY cursor capabilities and the FFT capabilities of the TDS3FFT module are also included.

The TDS3LIM module offers fast, simple verification that your circuit is operating within its intended parameters. You can easily create waveform reference templates to compare to your live waveforms. Compare any number of input channels with any combination of four references. And you can set actions for the TDS3000B to take if a waveform strays outside the reference limits: stop acquisition, sound a beep, print a hardcopy, or save the waveform to disk. The TDS3LIM is excellent for manufacturing test and other repetitive testing applications where quick go/no-go decisions are required.

When this module is installed, the TDS3000B becomes a Pass/Fail test instrument for telecommunications standard compliance testing.

• ITU-T G.703 (DS0, DS1, E1, Clk Interface, DS2, E2, E3, and DS3 rates) standards supported
• ANSI T1.102 (DS1, DS1A, DS1C, DS2, DS3, and STS-1 rates) standards supported
• Custom mask editing also available using WaveStar software
• Properly terminate your device under test with Communication Signal Adaptors
• Use TDS3GV Communication Module to program the TDS3000B for automated testing

Typical Application of TMT Module
When testing network line cards in manfacturing, one of the most important considerations is throughput. The combination of DPO waveform throughput and hardware assisted mask testing results in breakthrough test speeds for mask testing on single and multiple channel devices.

Extended Video Module TDS3VID

All TDS3000B Series oscilloscopes come standard with NTSC, PAL and SECAM (All Fields or All Lines) triggering capability. The TDS3VID application module extends this basic video triggering by adding the following features:

New in TDS3VID: Video Picture, Vectorscope, HDTV Triggering
These three great capabilities, originally available only in the TDS3SDI module, have been added to the TDS3VID module.
Video Picture Mode - The Video Picture feature enabled by the TDS3SDI or TDS3VID module lets you quickly check out a monochrome image of the originating camera or other source. Then use the on-screen line select to move quickly to any line in the picture.
Built-in Vectorscope Capabilities - Enabled by the TDS3SDI or TDS3VID module, a TDS3000B Series oscilloscope can function as a vectorscope with built in graticules for 100% and 75% color bars. It’s easy to measure chroma levels. The TDS3000B’s digital phosphor display makes it easy to see your white balance problem so you can adjust the camera to solve it.
Analog HDTV Triggering - The TDS3SDI and TDS3VID also let you work with emerging analog HDTV standards. Trigger on a range of HDTV formats – 1080i, 1080p, 720p, and 480p. Use the vectorscope on analog HDTV with graticules for both 100% and 75% color bars.

Other features include:
Video QuickMenu - Allows you to display a bottom and side menu that contains video functions useful for displaying and measuring broadcast standard waveforms, including trigger source, when to trigger, video graticule and video autoset.
Video Autoset - Automatically adjusts the vertical, horizontal and video trigger settings to display a video waveform triggered on all lines and fields. You can then manually adjust controls to optimize the display. This function is available in the Video QuickMenu and in the Acquire menu.
Custom Video - Allows you to specify custom horizontal scan rates in order to trigger on non-broadcast video waveforms, such as those used by computer monitors and medical equipment displays.
Line Count Trigger - Allows you to trigger on any particular line by scrolling through the line numbers and selecting the one you want.
Field Holdoff - Provides the capability to specify a number of fields to wait before re-enabling triggering. This allows you to trigger on a single filed (e.g. field 1 or field 3 of NTSC) instead of both field 1 and field 3.
Video Graticules - Provides the capability for the user to change the standard oscilloscope graticule to either IRE or mV depending on the signal format. Video graticules make it easier to measure and analyze video waveforms.

Serial Digital Video Module TDS3SDI

• Converts 601 digital video to standard analog video
• Composite and component video outputs
• Auto detects 525/60 or 625/50 formats
• Video picture mode to identify incoming signals
• Vectorscope mode to check adjustments
• Triggering for analog HDTV

The TDS3SDI module converts digital video to analog video so broadcast engineers and technicians can see and diagnose problems clearly. The module features a video picture identification, where the operator can choose to view the signal in monochrome, as it would appear on a television monitor-ideal for quick signal identification. The module also features vectorscope mode, with graticules for 100 percent and 75 percent color bars and HDTV. Video picture identification and vectorscope mode allow broadcast engineers and technicians to view digital streams just as they are accustomed to viewing analog video signals, thereby speeding analysis times. The TDS3SDI module plugs quickly into the rear of the TDS3054B and supplies 4 BNC connections for the component and composite video signals.
