Tektronix 4000 series oscilloscope

Introduction to Tektronix 4000 Series (Basic Function Demonstration)

1. Demo I: Collecting Signals

Step: ① Connect the oscilloscope (front/rear panel USB port) to the device port on the demonstration board using a USB cable; ② Confirm that the "USB POWER" LED on the demonstration board is on; ③ P6139A probe (channel 1) is connected to the demonstration board "GND" and "CNT CLK" (synchronous counter clock); ④ Press' Default Setup 'to reset; ⑤ Press' Auto Settings' to display multiple cycle clock signals.

2. Demo II: Using Vertical Controls

Operation: ① Rotate the vertical "scale" knob of channel 1 (observe the change in volts/grid, set to 1 V/grid); ② Rotate the vertical "position" knob (waveform centered); ③ Press the channel 2 button (switch channel 2).

3. Demo III: Using Horizontal Controls

Operation: ① Rotate the horizontal "scale" knob (observe time/grid changes, set to 20 ns/grid); ② Rotate the horizontal "position" knob (adjust the trigger position icon to the center of the screen); ③ Identify the display identifier (yellow bar=all collected, gray square brackets=current display section).

4. Demo IV: Using the Run/Stop Control

Operation: ① Press "Run/Stop" (stop collecting and display the last waveform); ② Press' Single '(stop after collecting a single waveform); ③ Press' Run/Stop 'again (restart collection).

5. Demo V: Using Trigger Controls

Operation: ① Rotate the trigger "position" knob (move it outside the waveform, and the waveform will randomly scroll); ② Press' Force trigger '(display single waveform acquisition); ③ Press' Set to 50% '(trigger level set to signal midpoint, stable trigger).

6. Demo VI: Using the cursor

Step: ① Press the "cursor" button (display vertical cursor, reading includes time/amplitude/increment); ② Use the multifunctional A/B knob to move the cursor (switch fine adjustment mode with the "Fine" button); ③ Measurement cycle (with the cursor placed at the midpoint of two falling edges, with a difference of approximately 100 ns); ④ Press the 'cursor' twice to close.

7. Demo VII: Measurement

Step: ① Press the "Measure" button; ② Click on the 'Select Measurement' button below; ③ Select "cycle" and "frequency"; ④ View readings (including value, average, minimum, maximum, standard deviation, such as frequency of approximately 10.0M); ⑤ Delete measurement ("Delete Measurement" → "Delete All Measurements"); ⑥ Press' Menu Off 'to close the menu.

8. Demo VIII: Saving Screen Images

Step: ① Insert USB/CompactFlash; ② Press' Save/Recall Menu '; ③ Select 'Save Screen Image'; ④ Multi function knob A selects the driver; ⑤ Press' Select '(expand/shrink directory); ⑥ Select file format (such as. png); ⑦ Press' OK to save screen image '; ⑧ Quick save (press the "Save" button, default image saved, can change saved content).

Tektronix 4000 Advanced Feature Demonstration

1. Overall packaging and performance

(1) Overall packaging advantages

10.4-inch XGA large display (high brightness, visually friendly);

Each channel has an independent vertical control knob (no need to select a channel first, efficient and intuitive);

Front and rear USB and CompactFlash ports (convenient for transferring data);

Thickness of 5.4 inches (saving workspace);

Weight 11 pounds (4.99 kilograms), with handle (portable);

Supports 11 languages (including Simplified/Traditional Chinese).

(2) Performance Parameters (Table)

Product Model Bandwidth Channels (DPO/MSO) Maximum Analog Sampling Rate (All Channels) Main Record Length (All Channels) MSO MagniVu Record Length (All Digital Channels)

DPO4104 & MSO4104 1 GHz 4 / 4+16 5 GS/s 10 M 10 K

DPO4054 & MSO4054 500 MHz 4 / 4+16 2.5 GS/s 10 M 10 K

DPO4034 & MSO4034 350 MHz 4 / 4+16 2.5 GS/s 10 M 10 K

DPO4032 & MSO4032 350 MHz 2 / 2+16 2.5 GS/s 10 M 10 K

Additional performance: All channels ≥ 5X oversampling (sin (x)/x interpolation, single full bandwidth); All channels have a record length of 10 meters; Support waveform labels.

2. Wave Inspector Demonstration

(1) Demo IX: Setting I2C Signal

Step: ① P6139A probe (channel 1 → SCLK, channel 2 → I2C SDA, all connected to GND); ② Confirm that the I2C LED is on (press "Serial SELECT" until it lights up); ③ Press' Default Setup '; ④ Trigger the "position" knob to set the trigger level to ≈ 2 V; ⑤ Open channel 2; ⑥ Channel 1/2 vertical "scale" is set at 2.0 V/grid, with positions at the top/middle of the scale respectively; ⑦ Press "Collect" → "Record Length" → "1M Points"; ⑧ Set the horizontal "scale" to 20.0 ms/grid; ⑨ Press' Single 'to display I2C clock (ch1 yellow) and data (ch2 blue).

(2) Demo X: Zoom and Pan Functions

Core control: Wave Inspector "pan/zoom" knob (outer ring=pan, inner ring=zoom);

Operation: ① Turn the zoom knob clockwise (enable zoom, display full capture/current display/zoom view); ② Amplify to a single clock pulse; ③ Translation knob (counterclockwise=left shift zoom box, clockwise=right shift, 10M recording length can be quickly moved); ④ Play/Pause "(automatically scrolling waveforms, adjusting speed/direction by moving the knob); ⑤ Set/Clear "(mark, solid white triangle=bookmark); ⑥ Arrow buttons (navigation markers).
