Procedure
1. Open up a W
eb browser on a PC and go to www.tek.com/product-support.
2. Enter the oscilloscope model number in the search field and click Go.
3. Scroll down the screen and click the Software tab.
4. If the listed available firmware version is newer than what is on your oscilloscope, select and download that file to your PC.
5. Copy the firmware install file to a USB drive.
6. Follow the instructions that are provided with the firmware to create the install files.
7. Insert the USB flash drive into any USB Host port on your instrument. The instrument automatically recognizes the firmware file and
starts the installation process.
8. Follow on-screen instructions. The instrument will take a few minutes to install the new firmware. Do not remove the USB flash drive
or power off the instrument during this time.
9. After the upgrade is complete, power off the instrument and remove the USB flash drive.
10. Power on the instrument.
11. To confirm the firmware update, locate the version number found in the About window under the Help.
12. Confirm that the instrument firmware version number matches the firmware version number that you just installed.
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.
About this task
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.
Before you begin
Disconnect all probes and cables from the front-panel channel inputs and rear-panel signal connectors.
Procedure
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.
About this task
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.
