Sony Tektronix 308 Data Analyzer with Probes and Instruction Manual

Description

• The 308 is a 20MHz portable analyzer containing a unique combination of features. It provides timing, state, serial, and signature analysis in an extremely easy to use package.
• This unit is complete with word recognizer probes and manual.Included:
• Model 308 Analyzer
• 2x Data Pods
• 1x BNC Data Probe
• 15x mini grabbers
• Power cord
• Pod Holder
• Original ManualModes of operation
• The Tektronix 308 Data Analyzer has four modes of operation:
• Timing analysis of parallel signals >li>State analysis of parallel signals
• State analysis of serial transmissions
• Signature analysis
• The Data Analyzer is similar to a logic analyzer functionally. However, its ability to analyze parallel signals makes it far superior than the rivalry logic analyzer. (back to TOP)
• Timing analysis of parallel signals
• The 308 provide an 8-channel input, a 20 MHz clock speed, and 52-bits/channel memory size when used as a Parallel Timing analyzer.
• The eight channel (expandable to 24 channel) parallel word recognizer triggers upon recognition of a preset digital word. If no preset data is presence, the 308 immediately and automatically generates an internal trigger at the start of an acquisition. Data sampling rate ranging from 50ns to 200ms (20 MHz to 5 Hz). An external clock or trigger signal can also be introduce to the 308 (via the Qualifier Input) as a synchronous sampling reference. The latch input allows the 308 to capture glitches narrow than the sample interval. Stored data is displayed on the CRT on digitized timing format representing the HI and LO levels of the stored data, but not the actual waveform. (back to TOP)
• State analysis of parallel signals
• The parallel state analyzer function is identical to the parallel timing Analyzer function except for the display. Data is displayed in binary, octal and hexadecimal formats. (back to TOP)Serial / Signature analysis:
• For Serial / Signature analysis, please visit my classmate’s web page on Logic Analyzer. (back to TOP)Controls and Indicators
• 1. DATA= — Programs instrument to receive data trigger.
• 2. EXT= — Programs instrument to receive external trigger word.
• 3. DELAY= — Programs instrument to receive clock delay setting.
• 4. & 5. SAMPLE INTERVAL FASTER/SLOWER — These controls select the sample interval of internal clock and clock edge of external clock. Sample interval is sequenced through 23 positions in parallel mode and 17 positions in serial state mode.
• 6. STORE DATA—>REF — Causes data memory contents to be duplicated in the reference memory.
• 7. START — Starts acquisitions process.
• 8. STOP — Stops acquisition process with manual stop trigger.
• 9. RE-START IF DATA=REF — Starts and restarts acquisition process of valid portion of new data memory contents are equal to the valid portion of the reference memory content.
• 10. & 11. POSITION — Moves window or cursor to earlier or later position. If key is pressed and held, position steps automatically.
• 12. CURSOR — Chooses cursor display in parallel timing, parallel state, and serial state modes.
• 13. WINDOW — Chooses window display in parallel timing mode.
• 14. SEARCH= — Chooses compare display in parallel and serial state modes.
• 15. COMPARE — Chooses compare display in parallel and serial state modes. Highlights the data which differs form data in the reference memory in inverse video.
• PARALLEL TIMING — Selects 8 channel parallel input signal to be stored and displayed in timing format.
• PARALLEL STATE — Selects 8-channel parallel input signal to be stored and displayed in hexadecimal, binary and octal formats. (back to TOP)Power Up:
• At power up, the 308 automatically perform a self-diagnostic procedure. If no errors are detected, the Parallel Timing Menu will be displayed. Otherwise, service is required. (back to TOP)Inputs:
• P6451 INPUT ONLY — The data acquisition probe can only be connected to this connector. The eight parallel bits of data acquired by the data acquisition probe are processed differently than the serial data; however, the data is stored in the data memory and display in the same manner.
• P6406 INPUT ONLY — The Word Recognizer probe can only be connected to this connector. It can be used to expand the 308 trigger capabilities. Keep in mind only the eight data bits acquired by the Data Acquisition probe will be stored and displayed.
• EXTERNAL TRIGGER QUALIFIER INPUT and T/C — This input can be used in several manners depending on the position of the T/C (Trigger/Clock) switch. Word recognition capabilities are extended when set to T. (back to TOP)Triggering :
• Any one of the eight inputs can be used as the trigger. Using the DATA= menu can specify trigger condition to set to either HI, LO or X (don’t care). An external trigger may also be used. (back to TOP)Data Acquisition:
• When the 308 is in the Sample mode, an internal or external clock can be used as the sample rate generator. Sample is taken at the pre-defined sample time; therefore the 308 may miss little glitches. On the contrary, glitches may be found and displayed by using the Latch mode. (back to TOP)Displaying Data:
• The PRE and POST key can be used to scroll the screen content horizontally. A single cursor can also be used to interpret the timing diagram into hexadecimal, octal, decimal or binary format. (back to TOP)Comparing Data:
• Data Memory copied into the Reference Memory can be compare to any later Data Memory contents by using the COMPARE key. Any difference found is highlighted in inverse video. (back to TOP)Included:
