GPU disclosure

This product utilizes a 3rd party device driver to enable the Graphics Processor Unit. The driver was obtained from NXP and requires the end user to accept an end-user licensing agreement.

This product uses Linux kernel version 3.0.35. If you wish to modify any of the GPL or LGPL components of the Linux kernel, and re-compile them, you will need to request a copy of the binary driver imx-gpu-viv-5.0.11.p4.5.bin from NXP. Instructions for compiling the kernel with the binary driver are below.

The GPU binary files rely on the gpu-viv driver package to be compiled into the kernel. This package can be found in the " drivers/mxc/gpu-viv" directory of this kernel distribution. To compile the package the user need only enable the following flags in the configuration file in the build configuration file named "Config-tek_lk-3.0.35":

CONFIG_IMX_HAVE_PLATFORM_VIV_GPU=y

CONFIG_DRM_VIVANTE=y

CONFIG_HAS_DMA=y

CONFIG_MXC_GPU_VIV=m

An end user who wishes to utilize this binary package will need to ensure that the binary files are placed into a suitable directory in their uImage linux boot file. The command line used for installing the galcore.ko module which starts up the GPU driver on an i.mx6 solo processor to perform 2D scaling is as follows:

" insmod /lib/modules/3.0.35/kernel/drivers/mxc/gpu-viv/galcore.ko" \

" registerMemBase=0x00000000 registerMemSize=0x00004000 irqLine=-1" \

" irqLine2D=42 registerMemBase3D=0x02200000 registerMemSize3D=0x00004000" \

" irqLineVG=43 registerMemBase2D=0x02204000 registerMemSize2D=0x00004000" \

" signal=48 baseAddress=0x80000000 fastClear=-1 " \

" contiguousSize=0x006f50000 contiguousBase=0x9E000000 "

Finally, in the board support configuration file, memory needs to be reserved for the GPU. An example of how to configure the board can be found in the following file: "/arch/arm/mach-mx6/ board-mx6q_sabresd.c". The salient lines are:

#include <mach/viv_gpu.h>

…

static struct viv_gpu_platform_data imx6q_gpu_pdata __initdata = {

.reserved_mem_size = SZ_128M,

};

….

imx_add_viv_gpu(&imx6_gpu_data, &imx6q_gpu_pdata);

…

#if defined(CONFIG_MXC_GPU_VIV) || defined(CONFIG_MXC_GPU_VIV_MODULE)

if (imx6q_gpu_pdata.reserved_mem_size) {

phys = memblock_alloc_base(imx6q_gpu_pdata.reserved_mem_size,

SZ_4K, SZ_1G);

memblock_remove(phys, imx6q_gpu_pdata.reserved_mem_size);

imx6q_gpu_pdata.reserved_mem_base = phys;

}

These probes build upon the functionality of the TekVPI interface. Each probe is matched with its corresponding oscilloscope channel, allowing the oscilloscope to optimize the signal input path. This provides AC compensation across the frequency band.

3. TPA-BNC Adapter

The TPA-BNC Adapter allows you to use TEKPROBE II probe capabilities, such as providing probe power and passing scaling and unit information to the oscilloscope.

4. BNC Interfaces

Some of these use TEKPROBE capabilities to pass the waveform signal and scaling to the oscilloscope. Some only pass the signal and there is no other communication.

5. Logic Probe Interface

The P6316 probe provides 16 channels of digital (logical one or zero) information.

6. The TPA-N-VPI Adapter allows you to use TekVPI probes with the RF input.

Connect TPP0250, TPP0500B, TPP1000, TekVPI+, TekVPI, or other supported Tektronix analog probes by pushing them into an input connector. The probe base latch locks with a 'click' when the probe is fully seated.

TekVPI probes automatically set the channel input parameters for that probe (bandwidth, attenuation, termination, and so on). If a probe has a Menu button, push that button to open an on-screen configuration menu. Follow instructions provided with active probes to set their parameters (auto zero, degauss, and so on).

Connect a BNC probe or cable by pushing it onto a channel BNC bayonet connector and turn the lock mechanism clockwise until it locks.

For more information on the many probes available for use with 3 Series MDO oscilloscopes, visit the Oscilloscope Probe and Accessory Selector Tool on the Tektronix website at www.tektronix.com.

Rackmount information

Note: Connecting a probe does not automatically enable that channel (make it active). Use the instrument controls or programmatic interface to turn on a channel and open its configuration menu to verify or change probe or cable settings (bandwidth, attenuation, termination and so on).

The optional RM3 Rackmount Kit lets you install the oscilloscope in standard equipment racks. The rack mount requires six rack units (6U) of space to install.

Contact Tektronix Customer Support to purchase the rackmount kit option RM3. Follow the instructions that come with the rackmount kit (RM3 Rackmount Kit Instructions, Tektronix part number 071-3609-xx).

1. Acquisition and Cursors controls:

MDO32, MDO34 Help 23

Getting acquainted with your instrument

■

Run/Stop starts and stops waveform acquisition. The button color indicates the acquisition status (green = running and acquiring; red = stopped). When stopped, the oscilloscope shows waveforms from the last completed acquisition. The Run/Stop button on the screen also shows the acquisition status.

■

Cursors button turns cursors on or off. Use the Multipurpose knobs to move the cursors. Double-tap the cursor readouts or on a cursor bar (line) to open the configuration menu to set cursor types and functionality. See

Display and configure cursors on page 82.

■

Fast Acq™ enables or disables the fast acquisition mode. FastAcq

provides high-speed waveform capture that reduces the dead time between waveform acquisitions, enabling the capture and display of transient events such as glitches and runt pulses. It is helpful in finding elusive signal anomalies. Fast acquisition mode can also display waveform phenomena at an intensity that reflects their rate of occurrence.

■

Single/Seq enables making a single waveform acquisition, or a specified number of acquisitions (as set in the Acquisition configuration menu). Pushing Single/Seq turns off Run/Stop mode and takes a single acquisition. The button color indicates the acquisition status (quick green flash = single acquisition acquired; solid green = waiting for trigger event). Pushing Single/Seq again takes another single acquisition.

■

High Res mode calculates the average of all the samples for each acquisition interval. High Res provides a higher-resolution, lowerbandwidth waveform.

■

Clear deletes the current acquisitions and measurement values from memory.

2. Multipurpose knobs:

3. Trigger controls:

■

Force forces a trigger event at a random point in the waveform and captures the acquisition.

■

Level sets the amplitude level that the signal must pass through to be considered a valid transition. The color of the Level knob indicates the trigger source except for dual-level triggers. The Level knob is disabled when the trigger type requires two level settings or other trigger qualifiers (set from the Trigger configuration menu). Push the knob to set the threshold level to 50% of the peak-to-peak amplitude range of the signal.

■

Slope sets the signal transition direction to detect for a trigger (low to high, high to low, or either direction). Push the button to cycle through the selections. The Slope button is disabled when the trigger type requires other slope qualifiers (set from the Trigger configuration menu).

■

Mode sets how the instrument behaves in the absence or presence of a trigger event:

■

Auto trigger mode enables the instrument to acquire and display a waveform whether or not a trigger event occurs. If a trigger event occurs, the instrument displays a stable waveform. If a trigger event does not occur, the instrument forces a trigger event and acquisition and displays an unstable waveform.

■

Normal trigger mode sets the instrument to acquire and display a waveform only when there is a valid trigger event. If no trigger occurs, the last waveform record acquired remains on the display. If no last waveform exists, no waveform is displayed.

Run Signal Path Compensation (SPC)

Run SPC at regular intervals for best measurement accuracy. You should run SPC whenever the ambient (room) temperature has changed by more than 5 °C (9 °F) or once a week if you use vertical scale settings of 5 mV/div or less.

Signal Path Compensation (SPC) corrects for DC level inaccuracies in the internal signal path caused by temperature variations and/or long-term signal path drift. Failure to run SPC on a regular basis may result in the oscilloscope not meeting warranted performance levels at low volts per division settings.

Prerequisite: Disconnect all probes and cables from the front-panel channel inputs and rear-panel signal connectors.

1. Power on and warm up the oscilloscope for at least 20 minutes.

2. Tap Utility > Calibration.

3. Tap Run SPC. The SPC Status readout shows Running while SPC is

running. SPC can take several minutes per channel to run, so wait until the SPC Status message changes to Pass before reconnecting probes and using the oscilloscope.

4. Close the Calibration configuration dialog when SPC has completed.

5. If SPC fails, write down any error message text. Make sure that all probes

and cables are disconnected and run SPC again. If SPC still fails, contact Tektronix Customer Support.

Compensate TPP0250, TPP0500B, or TPP1000 probes

Probe compensation adjusts the high frequency response of a probe for best waveform capture and measurement accuracy. The oscilloscope can automatically test and store compensation values for TPP0250, TPP0500B and TPP1000 probes.

The oscilloscope stores the compensation values for each probe/channel combination and automatically recalls the compensation values when you plug in the probe again. Probe compensation status is shown in the Probe Setup panel of the Channel configuration menu.

■

If the Probe Compensation Status field displays Pass, the probe is compensated and ready for use.

■

If the Probe Compensation Status field displays Default, the attached probe has not been compensated and needs to have this probe compensation procedure run.

■

If the Probe Compensation Status field displays Fail, the attached probe has failed the probe compensation procedure. Reconnect the probe and run probe compensation again.

■

If there is no probe compensation status field shown in the panel, the oscilloscope cannot store compensation values for that probe. See the oscilloscope Help for how to manually compensate passive probes not supported by the probe compensation function.

■

Each compensation generates values for a specific probe and channel combination. If you want to use the probe on another channel and desire to compensate the new probe-channel pair, you must run a new set of compensation steps.

■

Each channel can store compensation values for 10 individual probes. If you try to compensate an 11th probe on a channel, the oscilloscope will delete the values for the least recently used probe and add the values for the new probe.

Use this procedure to compensate a TPP0250, TPP0500B, TPP1000, or other supported TPP-family probe that shows a Default status when connected to the oscilloscope.

Note: A Default Setup does not delete probe compensation values. A factory calibration deletes all stored probe compensation values.

56 MDO32, MDO34 Help

Configure the instrument

Prerequisite: The oscilloscope must be powered on for at least 20 minutes before compensating a probe.

1. Connect a supported probe to an input channel.

2. Connect the probe tip and ground lead of the probe to the PROBE COMP

terminals on the lower right of the oscilloscope (see following image).

Figure 4: Probe Comp connections.

Connect the probe tip to the 1 kHz source and the ground clip to the ground. For best results, remove any probe tip accessories and hold the probe tip directly onto the 1 kHz connector.

Note: Connect only one probe at a time to the PROBE COMP terminals.

3. Turn off all channels.

4. Turn on the channel to which the probe is connected.

5. Push the front-panel Autoset button. The screen displays a square wave.

6. Double-tap the badge of the channel that you want to compensate.

7. Tap the Probe Setup panel.

If the Probe Compensation Status says Pass, the probe is already compensated for this channel. You can move the probe to another channel and start again from step 1 or connect a different probe to this channel and start from step 1.

If the Probe Compensation Status says Default, continue with this procedure.

8. Tap Compensate Probe to open the Probe Compensation dialog.

9. Tap Compensate Probe to run the probe compensation.

10. The probe compensation is finished when the Probe Compensation Status

displays Pass. Disconnect the probe tip and ground from the PROBE COMP terminals.

11. Repeat these steps for each supported passive probe that you want to compensate for this channel.

MDO32, MDO34 Help 57

Configure the instrument

12. Repeat these steps to compensate supported probes on other channels of the oscilloscope.

Note: For most accurate measurements, open the Probe Setup panel and verify the Probe Compensation Status is Pass whenever you attach a probe to a channel.

Note: A probe compensation failure is most likely due to intermittent connection of the probe tip or ground connection during the probe compensation operation. If a failure occurs, the oscilloscope will re-use the old probe compensation values if they existed prior to the failed probe compensation operation.

Compensate passive probes

Probe compensation adjusts the high frequency response of a probe for best waveform capture and measurement accuracy. Use this procedure to adjust probe compensation for probes with a manual adjustment.

A passive probe is only adjusted for one channel at a time. If you move a passive probe to another channel, you must compensate that probe to that channel.

1. Connect the probe to the channel where you want to use it to take measurements. Remove all other probes.

2. Turn on the channel to which the probe is connected. Turn off all other channels.

3. Attach the probe tip and reference lead to the probe compensation connectors.

4. Push the Autoset button to display a square wave.

5. Adjust the vertical Scale and Position knobs to display as large a waveform

as possible.

6. Use the adjustment tool provided with the probe to adjust the probe until the square wave has as flat a top as possible. See your probe manual for adjustment location and instructions.

ESD prevention guidelines

Electrostatic discharge (ESD) can damage oscilloscope and some probe inputs. This topic discusses how to avoid this type of damage.

ESD is a concern when handling any electronic equipment. The instrument is designed with robust ESD protection, however it is still possible that large discharges of static electricity directly into the signal input may damage the instrument. Use the following techniques to prevent electrostatic discharge from damaging the instrument.

other end to the HDMI connector on the oscilloscope.

Discharge the static voltage from your body by wearing a grounded antistatic wrist strap while connecting and disconnecting cables, probes, and adapters. The instrument provides a ground connection for attaching a wrist strap (above the Probe Comp ground connector).

■

A cable that is left unconnected on a bench can develop a large static charge. Discharge the static voltage from all cables before connecting them to the instrument or device under test by momentarily grounding the center conductor of the cable, or by connecting a 50 Ω termination to one end, before attaching the cable to the instrument.

MDO32, MDO34 Help 63

Configure the instrument

■

Before you apply power, connect the instrument to an electrically-neutral reference point, such as earth ground. To do this, plug the three-pronged power cord into an outlet grounded to earth ground. Grounding the oscilloscope is necessary to ensure safety and to take accurate measurements.

■

If you are working with static sensitive components, ground yourself. Static electricity that builds up on your body can damage static-sensitive components. Wear a wrist strap to safely send static charges on your body to earth ground.

■

The oscilloscope must share the same ground as any circuits that you plan to test.
