Page 41: Signal Path Compensation
Installation Signal Path Compensation Signal Path Compensation (SPC) corrects for DC inaccuracies caused by temperature variations and/or long-term drift. Run the compensation whenever the ambient temperature has changed by more than 10 °C (18 °F) or once a week if you use vertical settings of 5 mV/division or less. Failure to do so may result in the instrument not meeting warranted performance levels at those volts/div settings.
Page 42: Upgrading Firmware
Service personnel use the factory calibration functions to calibrate the internal voltage references of the oscilloscope using external sources. Refer to your Tektronix ﬁeld ofﬁce or representative for assistance with factory calibration. NOTE. Signal Path Compensation does not include calibration to the probe tip. (See page 12, Compensating a Passive Voltage Probe.)

Page 66: Acquire The Signal
Acquire the Signal Acquire the Signal This section describes concepts of and procedures for setting up the oscilloscope to acquire the signal as you want it to. Setting Up Analog Channels Use front-panel buttons and knobs to set up your instrument to acquire signals using the analog channels. 1.
Page 67 Acquire the Signal 5. Push the desired channel button. Then adjust the vertical position and scale. 6. Adjust the horizontal position and scale. The horizontal position determines the number of pretrigger and posttrigger samples. The horizontal scale determines the size of the acquisition window relative to the waveform.
Page 68 Acquire the Signal 2. Push Label on the lower menu to create a Label label, such as for channel 1 or B1. 3. Push Select Preset Label to view a list of Select Preset labels. Label 4. Turn multipurpose knob b to scroll through the list to ﬁnd a suitable label.

Acquire the Signal 3. Release Menu Off, and then release Autoset. 4. Select the desired side menu setting. Autoset Enabled Autoset Disabled Quick Tips To position the waveform appropriately, Autoset may change the vertical position. Autoset always sets vertical offset to 0 V.
Page 72: How The Analog Acquisition Modes Work
Acquire the Signal Waveform Record The instrument builds the waveform record through use of the following parameters: Sample interval: The time between recorded sample points. Adjust this by turning the Horizontal Scale knob or changing the record length with the menu buttons.
Page 73: Changing The Acquisition Mode, Record Length, And Delay Time
Acquire the Signal Hi Res mode calculates the average of all the samples for each acquisition interval. This mode only works with real-time, noninterpolated sampling. Hi-Res provides a higher-resolution, lower bandwidth waveform. Envelope mode ﬁnds the highest and lowest record points over all acquisitions. Envelope uses Peak Detect for each individual acquisition.
Page 74 Acquire the Signal 3. Then choose the acquisition mode on the Acquisition Mode side menu. You can chose from: Sample, Peak Detect, Hi Res, Envelope, or Average. Sample NOTE. Peak Detect and Hi Res modes take advantage of sample points that the oscilloscope would have discarded at lower Peak sweep speeds.
Page 75: Using Roll Mode
Acquire the Signal 7. Push Delay on the lower menu to select On when you want to delay the acquisition relative to the trigger event. With Delay set to On, turn the Horizontal Position knob counterclockwise to increase the delay. The trigger point will move to the left and ultimately outside of the acquired waveform.
Page 76: Setting Up A Serial Or Parallel Bus
Acquire the Signal Setting Up a Serial or Parallel Bus Your oscilloscope can decode and trigger on signal events or conditions that occur on: Bus type With this setup Parallel MSO3000 oscilloscope C and SPI DPO3EMBD application module.

Page 89 Acquire the Signal 7. Turn multipurpose knob a to scroll through the list of digital channels. Turn multipurpose knob b to position the selected channel. As you position channels close to each other on the display, the oscilloscope groups the channels, and adds the group to the pop-up list.
Page 90: When And Why To Turn On Magnivu
When and Why to Turn On MagniVu For MSO3000 Series only, MagniVu allows you to have higher resolution to accurately determine edge placement. This helps you to make precise timing measurements on digital edges. You can see up to 16 times more detail than with normal digital channel sampling.
Page 91 Acquire the Signal 2. Push MagniVu and select On. D15 – D0 Thresholds Label MagniVu Height On/Off |Off | M L Quick Tips If you think you need more timing resolution, turn on MagniVu to increase the resolution. MagniVu is always acquired. If the oscilloscope is in a stopped state, you can turn on MagniVu and still get the resolution without taking another acquisition.
Page 92: Trigger Setup
Trigger Setup Trigger Setup This section contains concepts and procedures for setting up the oscilloscope to trigger on your signal. Triggering Concepts Trigger Event The trigger event establishes the time-reference point in the waveform record. All waveform record data is located in time with respect to that point.
Page 93 Trigger Setup Trigger Holdoff Adjust holdoff to obtain stable triggering when the instrument is triggering on undesired trigger events. Trigger holdoff can help stabilize triggering, since the oscilloscope does not recognize new triggers during the holdoff time. When the instrument recognizes a trigger event, it disables the trigger system until acquisition is complete.
Page 94 Trigger Setup 1. Adjust the position (delay) time by rotating the Horizontal Position knob. 2. Turn horizontal SCALE to acquire the detail that you need around the position (delay) expansion point. The part of the record that occurs before the trigger is the pretrigger portion. The part that occurs after the trigger is the posttrigger portion.

Analyze Waveform Data Using Math Waveforms Create math waveforms to support the analysis of your channel and reference waveforms. By combining and transforming source waveforms and other data into math waveforms, you can derive the data view that your application requires. NOTE.
Page 135: Using Fft
Analyze Waveform Data Using FFT An FFT breaks down signals into component frequencies, which the oscilloscope uses to display a graph of the frequency domain of a signal, as opposed to the oscilloscope's standard time domain graph. You can match these frequencies with known system frequencies, such as system clocks, oscillators, or power supplies.
Page 136 Analyze Waveform Data 7. The FFT will appear on the display. Quick Tips Use short record lengths for faster instrument response. Use long record lengths to lower the noise relative to the signal and increase the frequency resolution. If desired, use the zoom feature along with the horizontal Position and Scale controls to magnify and position the FFT waveform.
