Tektronix MSO4000/DPO4000 series digital fluorescence oscilloscope

Document Overview

This manual is the official guidance document for the Tektronix MSO4000 (mixed signal) and DPO4000 (digital fluorescence) series oscilloscopes, covering 2-channel (such as MSO4032/DPO4032) and 4-channel (such as MSO4054/DPO4104) models, with a core focus on high-end electronic design and debugging (such as embedded systems, automotive electronics, communication equipment). The document structure includes 11 core chapters and 1 appendix, catering to the complex analysis needs of novice operators and professional engineers, highlighting the ability to synchronously collect and decode "analog+digital" mixed signals, as well as professional measurement functions extended through application modules.

2. Core Features

Mixed signal analysis (MSO series exclusive): 16 digital channels and analog channels are synchronously collected, supporting MagniVu mode (60.6ps timing resolution), which can capture narrow pulses and edge jitter of digital signals;

High speed signal processing: The highest sampling rate for all channels is 5GS/s, with a recording length of 10M points. It supports a refresh rate of 50000 waveforms per second and can quickly capture transient anomalies;

Flexible triggering and decoding: 8 types of triggering types cover edge, pulse width, logic mode, and bus (such as I2C/CAN/RS-232), supporting sequence triggering (A event+delayed B event);

Professional Expansion Module: Extend functionality through modules such as DPO4PWR (Power Quality/Switching Loss Measurement) and DPO4USB (USB 2.0 Decoding) to meet vertical domain requirements;

Convenient data management: Supports CompactFlash, USB storage, Ethernet remote control (e * Scope), USBTMC protocol for direct connection to PC.

Safety operation standards

1. Electrical safety

Input voltage limit:

1M Ω input: maximum 400Vpk (DF ≤ 39.2%), 250V RMS (below 130kHz), 20dB/decade attenuation above 130kHz;

50 Ω input: maximum 5V (peak to peak value ≤± 20V), automatically switches to 1M Ω protection when overvoltage occurs;

Probe safety:

P6139A passive probe: CAT II 300V RMS, CAT III 150V RMS, with 20dB/decade attenuation for frequencies above 2.5MHz;

Logic probe P6516: maximum input ± 15V, threshold accuracy ± (100mV+3% threshold);

Grounding requirements: A 3-pin power cord must be used, and the equipment chassis must be reliably grounded. Floating operation is prohibited; During measurement, the reference end of the probe should only be connected to the signal ground and should not be connected to the mains ground.

2. Operation taboos

Do not use in damp (>90% RH) or explosive environments, and avoid liquid contact with equipment;

Before connecting/disconnecting the probe, the signal source must be disconnected first, and live plugging and unplugging are prohibited;

Before disassembling the application module or CF card, it is necessary to shut down and avoid short circuiting the battery or probe contacts.

Basic operation process

1. Probe operation and calibration

Key requirements for operation type steps

Passive probe compensation (P6139A) 1. Probe connected to CH1, set to 10X; 2. Connected to PROBE COMP（ 2.5V@1kHz ）； 3. Autoset； 4. Adjust the compensation hole to a flat square wave without overshoot/depression, and re compensate every time the channel is changed

Signal Path Compensation (SPC): 1. Disconnect all probes and preheat for 20 minutes; 2. Press 【 Utility 】 → 【 Calibration 】 → 【 Signal Path 】; 3. Wait for 10 minutes and display "Pass". If the environmental temperature difference exceeds 10 ℃ or once a week, ensure low range (≤ 5mV/div) measurement accuracy

Firmware Upgrade 1. Download firmware. img from the official website to the USB root directory; 2. Turn off the oscilloscope and plug it into a USB port, and it will automatically upgrade when turned on; 3. After upgrading, verify the version (Utility ->Config ->About). During the upgrade, it is forbidden to power off or unplug the USB. It is recommended to use a blank USB to avoid file conflicts

2. Channel settings

Simulation channel:

Press the CH1-CH4 button to activate the channel, press 【 Coupling 】 to select DC/AC/GND (AC coupling blocks DC, GND displays reference ground);

Select 1M Ω/50 Ω (50 Ω only DC/GND coupling, maximum 1V/div) according to the 'Impedance' button;

Select Full/250MHz/20MHz (20MHz is used to filter out high-frequency noise) according to [Bandwidth];

Digital Channel (MSO Series):

Press 【 D15-D0 】 to activate the digital channel, and press 【 On/Off 】 to select D7-D0/D15-D8;
